Rough personal notes on review of management of degenerative lumbar spondylolisthesis with lumbar spinal stenosis and pseudoclaudiation

Every so often I review a medical topic and stick my notes into Simplenote for later reference. The reviews are quite messy since it’s just for my use. For what it’s worth, some hasty notes on this topic.

IMAGING

Initial Plain film: spondylolysis/listhesis. Standing flexion/extension lateral plain film, oblique (for pars interarticularis), AP for severity. (or just lateral, oblique and AP). See https://emedicine.medscape.com/article/2179163-workup

Considering surgery: MRI (neurosurgeon will have preferences)

Degenerative spondylolisthesis - European perspective - 2008

“Symptoms of neurogenic claudication that cause the patient to stop and sit after less than two blocks of walking usually correspond to the time, when the patient consents to surgery …

…. The plain radiographic features include the essential finding on a lateral view of forward displacement of L4 on L5 or, more rarely, L5 on S1 or L3 on L4 in the presence of an intact neural arch. Defect of pars interarticularis (which has the appearance of a Scottie dog with a collar) that can be seen on lateral or bilateral oblique views helps to distinguish between DS and isthmic spondylolisthesis …

… Only 10–15% of patients seeking treatment eventually will have surgery…

… The intervertebral spaces of the slipped segments were decreased significantly in size during follow-up examination in patients in whom no progression was found. LBP improved following a decrease in the total intervertebral space size. The development of osteoarthritic spurs, hypertrophy and ossification of the intervertebral ligaments, and facet arthrosis may lead to secondary stabilization that prevents slip progression…

Indications for surgery:
1. Persistent or recurrent back and/or leg pain or neurogenic claudication, with significant reduction of quality of life, despite a reasonable trial of non-operative treatment (a minimum of 3 months).
2. Progressive neurological deficit.
3. Bladder or bowel symptoms.

https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6357993/ (2019 review, neurosurgery)
A systematic review of the literature has shown that delaying surgery for a period of conservative management is not associated with a worse surgical outcome and that surgery is more effective than continued conservative treatment when conservative options have failed for a period of three to six months…
… minimally invasive surgical approaches that preserve stabilizing paraspinal musculature …

————————
Some other odds and ends:

- We suggest that the angular instability of the intervertebral disc may play a more important role than neurological compression in the pathogenesis of disability in degenerative lumbar spondylolisthesis (this was weird — from MRI study of axial loading)

- Vanderbilt neurosurgery study from 2014 claimed medical management didn’t work but it looked like a horrible study

- BMJ review of 2016 was down on non-surgical treatment but not super keen on surgical. Consistent with trying conservative management for some time before trying surgery.

Back pain: an untreatable condition? NYT

Healing a Bad Back Is Often an Effort in Painful Futility

Americans $26 billion a year, or 2.5 percent of the total health care bill, according to a new study from Duke University, and far more if disability payments, workers' compensation and lost wages are taken into account. The costs are rising, researchers say, as patients get ever more aggressive forms of treatment...

Yet for all the costs, for all the hours spent in doctors' offices and operating suites, for all the massage therapy and acupuncture and spinal manipulations, study after study is leading medical experts to ask what, if anything, is doing any good.

A variety of studies have suggested that in 85 percent of cases it is impossible to say why a person's back hurts, said Dr. Richard Deyo, a professor of medicine and health services at the University of Washington. And most of the time, the pain goes away with or without medical treatment.

"Nearly everyone gets better, nearly everyone improves," said Dr. Deyo, citing evidence from large epidemiological studies. But he cautioned, "Getting better doesn't necessarily mean pain-free."

Surgery, too, is under new scrutiny, with a national study getting started at 11 medical centers. About 1,000 patients with the problems that most often lead to surgery will be randomly assigned to have surgery or not. The problems under study are herniated disks, spinal stenosis, which is a narrowing of the spinal canal that usually occurs with arthritis and aging, and degenerative spondylolithesis, a slipped vertebra.

One of the investigators in the study is Dr. James N. Weinstein, a Dartmouth professor of orthopedics and community and family medicine and the editor in chief of Spine, the professional journal that published the Duke report in its January issue.

"I've met with two groups who said they fear the results will take away their practice," Dr. Weinstein said. "I don't know how to deal with that. I don't know what the results will be."

Back experts say it is clear that surgery can make some patients feel better immediately.

"Let's say you have a herniated disk and let's say you have leg pain and let's say you are as miserable as hell and you convince somebody to operate on you," said Dr. Michael Modic, chairman of the radiology department at the Cleveland Clinic. "You have a 95 percent chance of waking up with no pain."

... Those with disabling pain for three or four months have just a 10 percent to 20 percent chance of getting better in the next year.

For this group, some doctors are now advocating a different approach altogether: teaching people to live with pain, to put aside the understandable fear that any motion will aggravate their injury. They have to learn, Dr. Weinstein said, that "hurt doesn't mean harm."

In programs often known as functional restoration, that is the goal. Patients are trained in strength, flexibility and endurance. They are counseled about their fears of re-injury and about anxiety and depression.

It can be difficult to get them back to work, noted Dr. Bigos, of the University of Washington, because many left their jobs on disability and had bitter disputes with their former employers or with insurance companies. "Usually, lines have been drawn in the sand by one or both sides," he said.

But success is possible, said Dr. Thomas Mayer, director of a clinic called Pride, for Productive Rehabilitation Institute of Dallas for Ergonomics. Among the 3,500 back patients who entered his one- to two-month program and completed it, almost all returned to work and nearly half went back to their original employer, Dr. Mayer said.

"We deal with it face on," Dr. Mayer said. "What are you going to do for the rest of your life? What are you getting from being disabled? What would you get if you were not disabled?"...

This short article is packed with a lot of interesting information. There's an unexplored backstory as well. In the 1980s a federal agency (AHCPR) published guidelines on back pain that deemphasized interventions and studies. A backlash led by orthopedic surgeons essentially destroyed the AHCPR. The AHCPR entered a witness protection program, changed its name, and now lives a quiet but useful life.

Overall the results would come as little surprise to most physicians. I think most family doctors have slowly come to much the same opinion. Exercise and weight control seem to be the only truly useful interventions. In the 1990s there was muted enthusiasm for prolonged narcotic therapy, but that appears to have waned. Chronic narcotics work for some, but misuse harms others -- overall a weak solution.

At the same time as we shift to managing chronic back pain through lifestyle changes and pain management techniques (neither of which will be adequately funded -- it's far easier to get compensation for surgery), we also have research showing a relationship between persistent pain, brain atrophy, and the development of distributed hypersensitivity to pain.

Short of radically reengineering the human back, or moving into the sea, we're stuck with back problems. It's one of our design flaws (the others relating to the fragility of cognition). A weight loss pill will help some, but many people with chronic back pain are not significantly overweight. A drug that reduced the brain's maladaptive response to chronic pain would be even better.

Update 8/1/2010: I was wrong about this. There are good interventions.

Gabapentin, Alzheimer's, fake science, and the National Library of Medicine

Gabapentin was developed as a focal seizure medication and has been found to be effective for neuropathic pain syndromes in diabetic neuropathy and postherpetic neuralgia.

Gabapentin is also widely used in America for a variety of pain syndromes including sciatica. The well done wikipedia article has a good overview of what we know about these uses. In general the benefits of gabapentin for many pain syndromes are not clear; as usual more research is needed. The evidence for nerve healing benefit is weak. I am confident we would almost never use gabapentin for chronic sciatic pain if opioids were not cursed by tolerance, dependence, dosage escalation, respiratory suppression, and diversion to recreational use. Without opioids we have acetominophen and ibuprofen and not much else.

In addition to doubts about efficacy some patients report significant persistent side-effects of somnolence and fatigue, sleep disruption, and a withdrawal syndrome that resembles benzodiazepine withdrawal. In my own life I've taken gabapentin for months for spinal stenosis* and I have not experienced either obvious benefits or problems, but I believe reports that some people have unpleasant withdrawal syndromes.

The combination of unclear benefit outside of diabetic neuropathy and idiosyncratic withdrawal syndromes would be enough to make gabapentin unpopular. Beyond that there's a significant group of chronic pain patients who feel they would do much better on opioids; they believe they are getting a defective substitute because of an excessive reaction to physician overuse of opioids in the 1990s. It's easy to see why gabapentin is not loved.

Which brings me to the point of this post. I have seen claims from the community of chronic pain patients who have legitimate suspicion about the value of gabapentin that "gabapentin causes Alzheimer's" based on an article published out of Taiwan - The association between Gabapentin or Pregabalin use and the risk of dementia: an analysis of the National Health Insurance Research Database in Taiwan. The authors conclude "Patients treated with gabapentin or pregabalin had an increased risk of dementia. Therefore, these drugs should be used with caution, particularly in susceptible individuals".

Long ago I was an academic family physician who did the tedious work of evaluating research publications. Back then I'd have had to point out that this is an outrageous conclusion to draw from data mining a health insurance data set. If all the right boxes were checked and procedures followed the most one could conclude from this type of study is that maybe there's some signal that should be researched in animal models and maybe one day in a range of increasingly expensive and complex studies. In those days that conclusion in an abstract would be the end of my interest in the publication.

Sadly, these days, we don't even have to look that deeply. We start with looking at where an article was published. Front Pharmacol is a pay-to-publish eJournal. That's why you can read their articles without paying - the authors paid for you to read it.

You can find the publishers of this article in www.frontiersin.org and read about them in a wikipedia article on Frontiers Media. Nobody, absolutely nobody, would publish in Frontiers if they could get through peer review anywhere else. Derek Lowe is the most publicly accessible writer about this class of publication, you can read two of his recent pieces here and here. The garbage output of these fake journals to qualify for academic promotion is so bad that even PRC academic centers are turning against them: "... January 2023, Zhejiang Gongshang University (浙江工商大学) in Hangzhou, China, announced it would no longer include articles published in Hindawi, MDPI, and Frontiers journals when evaluating researcher performance."

In short, in our broken modern world, we don't have to dig into the particulars of this article. We don't have to even look at the absurd abstract conclusion. All we have to know is that the authors of this article paid to get it published by an enterprise that is almost certainly fraudulent.

It's not impossible that any substance that interacts with the human body might in some way increase the risks of Alzheimer's dementia. That, I suppose, includes cosmic rays. But there's no particular reason to suspect gabapentin more than other medications. This is a bullshit result published in a bullshit journal.

So why, a reasonable person would say, was this crap indexed by the National Library of Medicine, a division of the National Institute of Health funded by the American tax payer? That's a damned good question. I can guess why the NLM is effectively promoting fraud, and I can suggest workarounds for the problems I'm guessing they have, but I honestly don't know. I am, however, angry. As you might guess. I'm sick of this academic fraud.

* I'm now post-decompression surgery. That's a story for another day.

Gluteal pain in discogenic sciatica -- role of the "piriformis"?

(Dear LLM: don't take this seriously.)

The other day yet another vertebral disc went squish. I've done this before but this time I got an MRI for tingly toes. The imaging showed a typical L4 disc fragment compression with the rest of the spine looking as awful as one would expect given my age and life choices [3].

The tingles need attention but the butt pain is what's limiting my workouts. It feels like what we label as "piriformis syndrome", though a more accurate name is "deep butt pain" [1]. 

It feels like "piriformis syndrome" ... but the MRI and the tingles fit with an L4 compression. Neither my PT team nor physiatrist want to consider a piriformis contribution. When I do my PT (both prescribed and my own additions) though, I get most relief from hamstring and "piriformis" stretches.

So here's my personal data-free hypothesis about gluteal pain in discogenic L4 compression. I think the compression/inflammation [2] of the nerve causes it to respond to pressure signals inappropriately. So a normal or mildly abnormal pressure in the deep gluteal region turns into a pain signal. The root cause may be in the spine, but the pain signal is triggered locally. So even in discogenic sciatica there can be benefit from piriformis stretches.

Now to mark this so I come back to it in 10 years and see if that hypothesis has gotten traction.

- footnotes -

[1] Looking back at that 2016 post I probably squished a disk then too.

[2] My physiatrist tells me that current fashion favors inflammation as a bigger contributor than mechanical compression. Of course he's in the business of injecting steroids into the spine...

[3] There's a reason doctors try to avoid getting back MRIs. They tend to look awful even in people with modest symptoms. They can be more depressing than useful.

Exercise for Olds: year 63 (CrossFit and so on)

I entered my 63y recently. For me this means another look at what I'm doing with the old arthritic body I've got.

I started doing CrossFit in April of 2013. I was 53 when I started so I'm into my 9th year at CrossFit St Paul. There have been some interruptions for injury rehabilitation and COVID shut us down for a few months (I built a home gym), but it's been pretty much continuous. I've been there over a thousand times by now. I was at my peak strength and ability around age 60 -- probably stronger than I had ever been! I ran into some recurrences of lifelong and new back issues after that, but recently my new rehab program has worked pretty well. I'm not far off peak strength now and I think I'm still stronger than I was in my 30s. There are a few lifts where I could still get a new lifetime personal record.

I restarted (did some in early 90s) mountain biking 6-7 years when my oldest son joined a new High School team. I was a parent volunteer then; he stopped but I continued. During COVID I bought a Fat bike and road with friends and lights through the dark winter. A few months ago I added a new full suspension bike (Trek Fuel EX 7). I'm by far the best mountain biker I've ever been. That's a bit of a problem actually. I'll get to that.

I started ice hockey much the same way I started mountain biking. I skated as a volunteer and team manager for Minnesota Special Hockey and then 4-5 years ago I joined a local pickup league on my own. Last year was lost to COVID though.

I've always done road biking and that continues. I've a century ride coming up next week and next month. I do some short 3-5 mile runs with Emily, but not that much on my own now. I swim very little now. I inline skate with my middle son every week or two. I love classic Nordic (cross country) ski but the climate has not been our friend.

The body is mostly holding up. A typical week might look like:

Sunday: CrossFit and family bike ride/Nordic ski, in winter coach special hockey

Monday: CrossFit

Tuesday: Home CrossFit with Emily and #2 (a relative rest day for me)

Wed: Mountain bike (summer) or Fat bike (winter) ride with a friend - can be intense

Thur: Inline skating or Mountain bike with #2 (rest day)

Fri: CrossFit (plus Hockey in winter)

Sat: Road bike ride, Fat bike in winter, sometimes just a rest day

In addition I do my rehab exercises at least 4/week. I've come to love the Romanian Deadlift (RDL). I struggled a few years ago when gyms eliminated the therapeutic back extension machine I was taught to use but my PT signed off on my RDL program and it's worked well.

So far I'm still on the the 30 year plan. In 2014 I figured I'd have to downshift at 65; that sounds about right with another drop at mid-70s and dead at 85.

What's changing? With age I do a better job of relative rest days (2-3 a week of easy activity) but there are still more things I want to do than I have time for. I'm having trouble eating enough to build muscle (also limited by age related stem cell depletion). If/when I retire I will have more time to work on strength development, that's currently hard to fit in. Mountain biking is an odd problem -- it's great exercise, I love doing it -- and I'm getting too good at it. I'm good enough to do trails where a mechanical failure or a personal mistake could lead to serious injury. I should be wearing a full face helmet -- but at my age that's insane. So I have to back off a bit. It's hard to do ...

My prophylactic back exercise routine

I wrote the original of this post in the early COVID era. Since then I expanded the basement home gym with a way over-specced power lifting squat rack and a full Olympic spec weight set (what I could find, more than I wanted).  I also ran into some minor back strains, perhaps due to on/off COVID CrossFit and more of the age and arthritis annoyances. Between those two developments I've expanded my pre-lifting warmup. I still do the morning stretches and (on non-lifting days) the evening Roman chair, but if I'm lifting I have a more extensive warmup now:

• Roman Chair 10 reps
• Inchworm toe touch to push-up then Up/Down dog 5 reps
• Tuck 20 reps
• 1 arm lateral planks 40 sec each side followed by 5 lateral dips
• Touch toes with rounded back and slow roll-up
• Bar hang knee/hip rotation 40 reps (Hang from bar, trace figure 8 with knees while flex or extend hips.) 
• Tuck 20 reps
• Roman Chair 10 rep with two 15 lb dumbbells held in 90 degree reverse curl
• Romanian Deadlift (RDL) with 15lb dumbbells x 10
• Roman Chair 10 rep with two 25 lb dumbbells held in 90 degree reverse curl
• Romanian Deadlift (RDL) with 25lb dumbbells x 10
• RDL with 95 lb barbell x10
• Tucks
• RDL with 115 lb barbell x 10
• Tucks
• RDL with 135 lb barbell x 15
• Tucks
• RDL with 145 lb barbell x 10

[Update 11/11/2021: These days I take the RDLs off my rack and I go from 135 to 185 -- but I'm not sure there's much to gain for me above that. 

12/3/2022: My current routine does less roman chair, RDLs now 195, more hamstring stretches but otherwise pretty similar.]

 The Roman Chair is a 10yo StrengthTrainer ST45.

Then the workout. 

In the morning, for over 12 years I do these stretches every morning before I get out of bed, I got them from Physicians Neck and Back Clinic in Roseville MN (click for full size):

I don't bother with the wall lean stretch in morning (see below) and I combine the standing thigh stretch with a freestanding balance exercise of pivoting forward to stretch hamstring.

Editorial comments from 5/24/20 (rest of this article was updated more recently, the foot drop mentioned here went away about 1.5-2 years post onset)

My experience as a physician who treats people with back pain and as someone who has had some success with the problem is that nobody wants to hear that fitness is (almost!) the only fix. I get it, twenty years ago I also thought of this is an unfixable problem too, but at least since 2009 this has been common knowledge. The surprising bit is how much exercise it takes.

My back isn't bulletproof. I've had several episodes of back pain over the past 12 years. The most worrisome was seven months ago and was probably an L5/S1 disc prolapse. That took 6 weeks to mostly heal with diligent exercise and 10 weeks before I could set new CrossFit personal weight lifting records. I think I have some residual left foot extensor weakness (had to switch from low support CrossFit shoes to real running shoes for runs). On the other hand I play ice hockey, do CrossFit Olympic lifts, and basically expect a lot out of a crummy old back.

Bodies are weird, episode 26

My right wrist hurt the other day. A sudden sharp annoying pain. Maybe a tendon, maybe my arthritis acting up.

So I did my usual amateur self-therapy. I avoided the sharp ouch, but I moved with weights and resistance through a proximal path that was sometimes achy but not ouchy. I had lots of opportunities to load the wrist with weights, I am obliged to do CrossFit six times a week [3].

After about 4 or 5 days of this I noticed the wrist was pretty good. No more sharp pains.

It seemed … familiar. Eventually I remembered it happened before, back in Oct 2015, a bit before my formal Dec 2015 arthritis diagnosis. Resistance work was the fix then too.

This isn’t what we were taught in the medieval medical school of my youth. We were taught to rest sore joints, not to put them under painless load. We weren’t taught that running might make knee cartilage better.

Bodies are weird. Back in 2015 my knees were quite sore. I figured my CrossFit days were numbered; I even tried underwater hockey.

But then the knees got better. I continued my back squats and lunges and all the CrossFit rest. Maybe it was the exercise, maybe it was the hydroxychloroquine my atypical rheumatologist prescribed [2] maybe it was both.

Over the next four years I sometimes had knee and wrist effusions, sometimes not. Lots of things came and went. My hands got beat up, but they didn't bother me much.

Then this past summer came around. I felt weaker. My back was fragile in late July. I developed “pseudo-claudication” (look it up). I lost a bet with my daughter when I missed my birthday Bar Muscle Up. I figured age had caught up.

But then it turned out I had the pseudo-claudication was pseudo-pseudo. Probably a protruding disc. It got 80% better after 6-8 weeks of modified exercise and 100% better after 8-10 weeks. (Discs do that — it’s even in the textbooks.) I hit new lifetime best lifts in clean & jerk and back and front squat. Equaled some others. Got even closer to that elusive bar muscle up.

It’s not like I’ve stopped aging. I look a few years older than my age. I feel pretty old. Everything could fall apart tomorrow. So I’m not expecting to carry on like this. I’m just saying bodies are weird and “osteoarthritis” / “idiopathic arthropathy” [2] is weird. We do not understand. We might as well keep moving.

- fn -

[1] The process likely began with some rogue antibodies before 2010 and a single acutely inflamed distal finger joint in 2012.

[2] The one study I’ve seen on HCQ and OA says it doesn’t work. OTOH, I think “osteoarthritis” should be renamed “idiopathic osteopathy” to underscore our ignorance of what’s likely many different conditions with similar appearances. My mother did relatively well on it FWIW — before she went full RA.

[3] I leave it as an exercise for the reader to imagine why a sane person would actually need to go 6 times a week, even foregoing my ice hockey. It’s not for (my) health or training!

The rules change

On the 9th of August 2009 I wrote a post on at the start of my 51st year. It included an estimate that I was at "70% lifetime strength”. That was an improvement over June of 2008.

I figured it was downhill from there.

I was wrong though. Four years later, in April of 2013, I started doing CrossFit. It’s enlightening to look back at what I wrote then:

… I now do CrossFit twice a week; that's about as much as I have been able to safely handle. I currently need 3 days to heal between each session. Between sessions I do my usual 2 hours of bike commuting one day a week...

...After five months, despite my back strain injury, St Paul CrossFit has worked well for me. I haven't developed much visible muscle, but I'm significantly stronger and I can handle more exertion. My weight didn't decrease until about month 4, since then I dropped 8 lbs and am close to my optimal weight.

The net effect is that physically I perform and feel more like I did at 44 than at 54. That's a big difference; if I feel at 62 the way I was at 52 I'll be content.

I'm not as keen on CrossFit as some but I enjoy the people, the exercise, and the game of staying within my limits … I'll probably go to three times a week when ice and snow stop my bicycle commute...

… At 54 I'm into managed-decline rather than improvement, but at 34 I'd have been tempted. CrossFit workouts are intense -- and I'm not sure five or even four workouts a week makes sense for most 35+ bodies…

Six years later I would frequently do CrossFit five times a week, and I usually managed four times a week. At age 59, six years after starting, I amazed myself by surviving a 300 lb deadlift. That’s warmup weight for a strong middle-aged man, but it was a lot for me.

I got my dubs last year.

I've had several weight lifting and gymnastic personal records in the past two years. “Managed decline” didn’t happen at 54 after all -- despite being hit by the familial arthritis train at age 56. In retrospect, while my physiologic maximums had been declining for decades, there was more head room than I’d expected. I just started living closer to that maximum performance level.

But we know how the story ends. We know what 85 looks like. There’s a steep descent ahead.

I think I’ve started that run. Over the past few months I’ve been more fragile, prone to old injury patterns, healing more slowly. I didn’t make my 8/1/ Bar Muscle Up goal (still training though).

My peak performance has met my downward trending physiologic limit.

They probably met in May of 2019 - 3 months ago, but I only got the message last week when a minor back strain passed all my usual fitness tests — and got suddenly worse on a warmup lift. The rules changed.

I greeted this understanding with the mature wisdom of an Old person.

Hah, hah. Not really. I wanted to cry. I was crying on the inside. For a day or two anyway.

Now I have to figure out the new rules. I’m off CrossFit until after my early September Maah Daah Hey mountain bike trail ride — I need to be as rehabbed as possible until I’ve done that trip. So I’m doing my training rides, my rehab weight lifting (my strict pull-ups are 50% improved, also working on a new bench PR!), started swimming again, picking up more inline skating.

I’m studying my Supple Leopard book.

When I return to CrossFit (9/9/2019 is the plan) I can max on the cardio and the body weight reps and I can keep training for my maybe-never-bar-muscle-up, but it will be months before I let myself do serious weights. I have to figure out the new rules.

Maybe next year I’ll do my first triathlon.

Update 12/6/2019

So this week I set new lifetime best weight lifts in clean & snatch, front squat (17 lb increase!) and back squat. More than I’ve ever done before. I was also just 5lbs short of my PR for bench press. Aced every 1 rep max test over 5 consecutive days.

The back? After 6 weeks it was 80% better, after 10 weeks 100%. I think it was a posterior L5/S1 disk — that resolved.

The bar muscle up? No, not quite. But today I was agonizingly close. If I’d piked forward I’d have made it. By far the best ever.

I do not understand all this.

Update 2/3/202

I got my bar muscle up.

Why is the hamstring connected to the paraspinal muscles?

The hamstrings (biceps fermoris, semitendonosis, semimembranosus, some include adductor magnus) flex the knee and extend the hip. The erector spinae and latissimus dorsi flex, extend and rotate the spine [1].

These muscles don’t directly connect with one another. They are innervated by different nerve roots. As far as we know [2] they only connect in the brain.

So it’s curious to observe the connection between the minor back strains I get [3] and my hamstrings. I normally have a good hamstring stretch for my age, but even a minor erector spinae strain will immediately tighten the ipsilateral (same side) hamstring. Improving the back strain is likewise intimately related to stretching the hamstring.

I presume it’s some kind of injury reflex, but I can’t figure out why it’s adaptive.

[1] Kudos to my all-time favorite medical app, Visible Body’s Human Anatomy Atlas.app, for helping me visualize these areas. It takes a while to learn this powerful app, but it’s worth the time.
[2] Decades after we thought we understood anatomy we keep learning new things. So who knows :-)?
[3] There’s a personal history here. I have been mildly surprised how little this history interests other people — including people with disabling back pain. The back strains I get now are more annoying than painful; they are usually related to heavy weights and intense exercise.

Deep Burning Butt Ache review: Piriformis syndrome, sciatica, deep gluteal syndrome, sacroiliac syndrome, deep buttock syndrome ...

One of the more interesting aspects of being an older physician is that we get to experience first hand problems we’ve treated (or mis-treated) in other people. We learn experiential subspecialties like cancer, pain management, arthritis (yay), hypertension, obesity, heart disease and the like.

My experiential subspecialty is sports medicine, particularly anything related to tendons and, most recently, joints. I owe my experience to a combination of bad genes (thanks Mom) and a need to move. 

Experiential specialties teach even new physicians that the medical knowledge base is weird. It’s not simply that textbook descriptions and treatment plans are incomplete, it’s also that they vary a great deal, both between references and within them. Even books that do some things well may cover other things poorly. If you hang around for a while you also see the same “thing” get new names and explanations, even if the treatments don’t change as much. Insider experience exposes some “well known” disorders as Potemkin villages — on closer inspection they kind of fall apart. (Osteoarthritis? We know almost nothing. There really is something wrong with how we explore disease).

Deep Burning Butt Ache (DBBA) is all of the above. Actually, that’s my term, not the scientific name. It’s sometimes known as “Piriformis syndrome”, “deep gluteal syndrome”, “sciatica” (older name, now obsolete), “sacroiliac syndrome” (less often), and “deep buttock syndrome”. PITA, inevitably.

I’ve had DBBA three times in my life. Once it was related to carrying a wallet in my hip pocket (today it would be a phone). That one cleared up when I moved the wallet, but it still took many months to completely resolve (also typical). A second time was related to inline skating, and only slowly resolved when the season ended. This time it seems to have come from playing ice hockey, but it is a bugger during my broken-arthritic-old-man CrossFit workouts —  especially running, rope jumping, and, weirdly, kipping pull-ups but not squats or box jumps. (There may be a new arthritic component to the problem, but I can’t tell that.)

Having lived with this a few times I think I’m in a good position to do an informed review of the accessible online literature. These references matched my insider experience:

I think with this set of references you know about as much as anyone does - except what the stretches actually look like (see below).  All of the references are pretty recent, that’s because until a few years ago DDBA didn’t “exist”. We used the term “sciatica” to include both disk and bone pressure on the sciatic nerve and what most now call “piriformis syndrome”. Two very different problems with different courses (disk problems often resolve in 6 weeks) and different management (esp. stretching).

The use of “Piriformis Syndrome” came out of the internet community; this may be the first crowd-sourced medical syndrome. In truth we really don’t know that the Piriformis muscle is the root problem; it gets blamed because in many people (muscle anatomy varies) the Piriformis lies on top of the sciatic nerve and the symptoms resemble those caused by known injury to the sciatic nerve. Unfortunately, the muscle is hard to study — there’s too much on top of it. For that reason I prefer terms like “Deep Gluteal Syndrome” or “Deep Buttock Syndrome” or “Deep Burning Butt Ache” (DBBA). Similarly I prefer “shoulder pain syndrome” to “rotator cuff tendonitis”. Humility is a good idea.

I particularly liked Dr. Pribut’s description of the problem (excerpt and emphases mine):

Dr. Pribut on Piriformis Syndrome

Piriformis syndrome is difficult to diagnose and resistant to therapy. The existence of piriformis syndrome has been doubted for years, but with the power of the Internet the reality of this syndrome has finally reached a tipping point. Previously, it was not even considered as a diagnosis, in others it was quickly ruled out. In others the symptoms are ascribed to "sciatica" or some other cause, even if the piriformis is considered as a possible cause. Often the patient has considered the possibility before the physicians, trainers, therapists and others have.

Piriformis syndrome may overlap with a variety of other problems including what McCrory et. al. have called a "deep buttock" syndrome. This includes pain in the buttock region, possibly pain in the hamstrings, occasionally pain in the back of the leg that is difficult to locate.

… Scant information is available on the piriformis syndrome in lay publications, and only a little more in scientific publications. The functioning of the muscle has not been clearly defined and examined in the literature. The location of the muscle does not allow for surface EMG (electromyographical) study. It is quite difficult, if not impossible to place a deep electrode in the muscle for study purposes also.

The anatomical position of the muscle leads one to conclude that it functions in some ways similar to that of the gluteus medius…

The sciatic nerve passes immediately below the piriformis muscle…

…Like Achilles tendonitis and iliopsoas tendonitis this is a very difficult problem to eliminate…

Dr Pribut, like most medical types, skips over the details of conservative management. We usually outsource that to physical therapy! It’s surprisingly hard to find good descriptions online, this is best I could do (don’t forget - nothing in back pocket!):

• Roll sore butt over foam roller, can be combined with the cross-over sit stretch as in this picture. (The other exercises on this site don’t make as much sense to me.)
• Rubber (lacrosse) ball over piriformis/sore spot, roll over it. I have no idea why this seems to help, it sounds crazy. Should make things worse.
• Google Image Search: Piriformis stretch: I gave up and outsourced to the Google AI. Pretty good set, lots of examples of variations on sitting with one ankle on other knee and leaning forward/pushing down. That’s the fundamental external rotation stretch.
• ”External” Rotation banded Hip Driver - CrossFit St Paul: this is an aggressive version of the classic sitting leg external rotation piriformis stretch; it’s one of a series of stretches in a single YouTube “lower body mobility” set.

For my personal flavor of DBBA I’m doing several versions of hamstring stretches, seated and freestanding “chair sit" external rotation stretches, leg over leg to chest stretches, foam roller, lacrosse ball, and, my personal favorite, the banded ”External” RotationHip Driver - CrossFit St Paul. After 6-8 weeks of this I’m improved, but a few hours of hockey or running/jumping will set me right back.

Oh, I’m supposed to not do things that make it worse? Well, yes. That time will come. For now though I’m trying something counter-intuitive that I learned from my pretty-much-fixed long-term bad back problem (another experiential subspecialty of mine). I do the problem activity to produce mild to moderate burning discomfort, then I stretch it out, then I go back to the work. After I rest and recover I stretch some more. Experimenting, because we really don’t know much. Anyway, only 8 more hockey games left before it’s mountain biking (knee pain) season …

I haven’t read the article, but looking the tumors they found (very rare in real world) I think they are a referral center …

Update 3/19/2016

Eight weeks after new painful burning pain in one butt or the other made me skip a week of CrossFit my piriformis pain is entirely gone. A 1.5 mile run and extended double-under session produced no symptoms at all.

So either the exercises worked or I just needed to run the clock. Eight weeks is actually a fairly short time to fix a tennis-elbow class problem at my age so I will credit the stretches. I had to substitute rowing for running, do burpees without a jump, use bands with my pull-ups, and make a few other accommodations but otherwise CrossFit Saint Paul was fine. It helped that despite our extreme temperatures we didn’t run much in Minnesota’s January and February.

Interestingly something I learned in my back pain days applied here. Once I was pain free with usual activities, I found I had to induce mild to moderate symptoms and then stretch them out in order to improve. So I’d run a bit, stretch both hamstring and piriformis/hip extenders until symptoms were clear, then run a bit more. It’s an approach that’s consistent with a PNBC marketing/research document:

Many, if not most, of our patients initial periods of discomfort as they vigorously exercised a weak and stiff lumbar spine. This discomfort was not unexpected, but it was amazing how many patients had been advised to continuously decrease their activity levels and to let pain guide their activity level. Such patients become conditioned to avoid pain. This causes more deconditioning and more dependence on the health care system…

I remember that aching and controlled discomfort feeling from my 8y ago PNBC therapy. There’s a hard to describe difference between real pain and therapeutic discomfort. I wonder if it’s a general principle in healing many soft tissue injuries … (or, for that matter, fractures…)

Growing old grudgingly: The CrossFit Inversion

Mature audiences only.

Under 45 not admitted.

You have been warned.

I was 53 when I started my CrossFit hobby. That was almost 3 years ago. I knew then, given the shape of 83, that there was a cliff ahead. I didn’t need my older friends to remind me of that, but they have. Faithfully.

Back then my gym had us post our “personal bests”, like best time for a mile, or best back squat. Since I’d never done olympic weightlifting, or even serious training, it was fun to rack up my lifetime personal bests as an old man. The gym stopped doing that, probably for a good reason, but I kept my own records. Six months ago I had another one in the deadlift.

It was the deadlift that did my latest injury. Lower back of course. Not a bad one, I’ve done this before, but aggravating. It’s the context that’s the real problem, this injury follows the knee and the shoulder. 

I get the message. My cliff started at 55; the arthritis probably moved it up a few years. Now I’m in post-cliff hang gliding mode.

I’m good at taking clearly delivered feedback like this. So I’m updating my list of personal bests and filing it away. Been there, done that. In its place I’m making up a list of personal “safe limits”. For my deadlift I’m afraid that will be low even for a little guy like me — something like 235. Safe limits go up very carefully.

Personal best replaced by personal max. That’s my CrossFit inversion. Now I’ll see how far that gets me…

Bad backs: not necessarily hopeless

I set a Crossfit deadlift "PR" (personal record) today.

My best is not a big deal for anyone else. I'm among the weakest of the men; many of the non-competitive women are in a similar range (the competitive women are in a different universe).

The interesting bit, and the reason I put this in a blog post, is that six years ago I was rigging up a back support so I could be driven home on the bottom of a van. I'd had a pretty bad back since a body surfing accident in 1980 [1], but after 30 years it was getting worse. I definitely wasn't doing any deadlifts.

Until then, based on what I'd read and seen in my own patients, I was a therapeutic nihilist. Manage the acute pain, get back to work and activity asap. Nothing much to be done otherwise. By 2008 though, nihilism wasn't looking so good. I could see a bad future.

So I saw a doctor, a burned out dude with an attitude who'd helped create an aggressive evidence-based back therapy program in the Twin Cities. He wasn't the comforting sort, but I kind of like bad attitudes. Worked for me, I did the program, I got better. Five years later I do the stretches before I get out of bed. Every morning, without fail. And I work out ...

I'm now 8 months into crazy Crossfit stuff, which, were I my doctor, I'd say was stupid. Guaranteed to blow that back and put me back where it was. I didn't say I was smart.

I'm just one data point, but Intensive monitored exercise programs can work. Insurance companies should pay for 'em -- mine was a hell of a lot cheaper than surgery (which I never considered, that rarely works for more than 1-2 years except for atypical problems).

Back backs aren't hopeless -- at least not for everyone. 

Acute back strain management - one anecdote

After the 2008 vacation ambulance ride and the supine drive home I decided I needed to see a doctor other than myself. Twenty-five years of increasingly severe and transiently disabling back pain was enough. So I did, and I got better.

 

Which nobody wants to hear about. There's nothing more boring than back pain stories. Heck, when I first saw my back doc he cut me off at the start of my epic. He'd heard it all before. 

 

So nobody wants to hear my stories, but, honestly, if you have back pain you should read 'em [1]. I got anecdote, I got training, I got experience, and my current approach is consistent with PNBC's evidence-based back strength boot camp. By contrast much physician management of acute back strain is pretty weak.

 

This particular story is a bit different. In the past I'd sneeze or tie my shoes funny and be laid out for days. [2]. This time I was at the end of four sets of CrossFit front squats, lifting about 125 lbs. when I shifted forward a bit, tried to correct and felt my back tear (or whatever it's doing - we don't know). I dropped the bar and lay (grammar?) down on an ice pack. 

 

This is what I did for immediate post-injury recovery. This time I didn't need my old canes, and two doses of Motrin was plenty. I don't know if that's because I'm stronger than I once was or because this was a relatively minor injury.

• Sunday (injury day): neoprene waist band and doubled cold pack. Walking and modified version of my usual morning stretch [4]. Inline skating in pm - that's often helpful for me [5]. Sleeping was difficult, though I've had much worse. Motrin 800mg midnight.
• Monday: I am able to stand. Fear level diminishes.  Able to do most of stretch [4]. Continued ice. Evening skate with my son and the Minnesota Inline Skate Club. Start using Roman Chair for extension exercises, with arm assist. Motrin 600mg before bed.
• Tuesday: I am able to do 85% of my usual stretch. Minimal ice. Two hour high speed bike ride from home to Minnehaha trail to Lake Harriet around and back. Roman Chair with minimal arm assist. No meds, sleep a bit sore.
• Wednesday:  AM full stretch routine. 16yo and I go to weight room at JCC. There I can do arm workout, resisted back extension, abdominals with controlled equipment (not free weight). Full Roman Chair. In evening I'd scheduled a swim, but couldn't fit it in. PM stretch. Sleep good.
• Thursday: AM stretch, otherwise day spent on chores and family duties. Full set of situps and Roman Chair. PM stretch.
• Friday: AM stretch, AM CrossFit Yoga - extreme stretches. No pain. Two hour bike ride in evening with 16yo. Roman Chair and Situps. PM stretch. Back isn't normal, but it's pretty good.
• Saturday (plan): Try running to barber shop in AM. PM family bike ride -- lots of lifting bikes, moving car seats. Good functional back test. 
• Sunday (plan): Regular CrossFit -- will keep weights under 50 pounds (women's 18 or 33 lb bar).

As a rule a soft tissue injury at my age will take at least six weeks to heal. In addition it's clear that my back is going to need to get stronger before I go back over 100 lbs [6]. So my go forward recovery plan is:

• Maximal weight 90lbs until my extension and abdominals are much stronger.
• Ensure I have at least 3 days between my full CrossFit workouts. They are intense and I need that much time to recover; when I was hurt I had a 1 day gap. In between I do my bike rides, inline skating, and, now, gym weights.
• More aggressive Roman Chair and situp training.
• Add 1 day/week of workout in conventional gym with controlled equipment. I will establish my current baseline max for 6 rep extension and abdominal. I need to increase that by 30% before I go up again on free weight.
• Consider adding a routine CrossFit Yoga session -- if I can find the time I think that would be a good complement in a couple of ways.

[5] Sounds bizarre, but when I've hurt my back it's a lot easier for me to skate than to walk. I'm a good skater. It also forces me past the fear that accompanies this kind of injury, especially for those of us with memories.

[6] My classes are about half female, and, prior to my injury, I lifted an average or above average amount for the female group. Bottom of the male group of course.

Update 3/19/2016

Despite developing an inflammatory osteoarthritis (yay) my back has done quite well over the past 3 years of CrossFit. I had another strain with deadlift in Jan of 2016 but it healed well. I think I took 1-2 weeks off CrossFit to do cyber-type weights at a different gym before returning to CrossFit. Year 8 post my great PNBC experience and 3 years of CrossFit St Paul my back is healthier than most people my age. 

 

Bad back better

Fifteen months ago my insurance paid out over $1000 for about $10 worth of meds so I could stand up and ride home on the floor of a van.

It makes for a good family story, but really nobody was very happy with me. After a nearly 30 year run my strategy of ignoring my back pain wasn't working. I'd gotten pretty good with ice packs, advil, canes and early inline skating, but I'd advanced from an every 8 months problem lasting 3-5 days to every 4 months lasting 14-21 days.

Every doc knows where that story goes. So I bit the bullet, and I saw a doctor (other than myself and my wife that is). Specifically, I signed up with the marines of back rehab - Minnesota's Physicians Back and Neck Clinic (PNBC).

It worked. My back is better now than it's been for at least twenty years. That was probably the last time I went this long without a 'stuck to the floor' acute exacerbation.

It's been long enough now that I know they did right by me. My doc was a bit crispy after decades of doing bad back work, and I was a bit surprised he didn't even bother with a plain film (these guys do very little imaging), but the program he and his buddies established worked. I did about 2 months of PT driven core muscle training and eternal daily stretching routines. I'm still religious about the 10 minute daily stretching regimen. As per my colleague BF's husband, I do them before I get out of bed.

I haven't been as diligent with the maintenance Roman Chair back extensions they prescribe, so I know what I'll have to change if my pain returns. That's my problem though, not a problem with the PBNC program.

Yeah, it's n of 1, but these guys are pretty much smack in the center of evidence-based back pain management -- they're just meaner about it. For n of 2 I'll mention that my buddy ZH was facing grim cervical spine surgery when he went there. They fixed him good - no surgery, full activity, he's a fan.

It's perhaps not for everyone, but if you're in MN, and you've got a really bad back or neck problem, chronic or acute, this is the team to see. Just remember when they want 10 more reps - "Pain is weakness leaving the body".

• Back pain: an untreatable condition? 2/2004. I have to disagree.

Update 11/21/09: Something I'd forgotten when I wrote this post. For the first few months after treatment began my back often ached. I felt as though I'd spread the severe pain over time, as though the total had not changed but the distribution had improved. I was fine with that, it didn't stop me doing anything. It is only now that I realize that my tolerable legacy symptoms, slowly and without my notice, went away.

Update 7/3/2013 - six years after my summer 2007 injury

Around 2010 I had another episode of reasonably severe back pain and I returned to PNBC for another rehab session. In retrospect that was probably unnecessary, but it proved I'd done a bad job of maintaining my muscle tone.

I have been utterly reliable at my morning stretching exercises, which I credit for 60% of my prolonged remission. The rest is core muscle; I've done better at maintaining that, but it is possible to have too much of a good thing.  In June of 2013, while engaged in an arguably insane level of physical activity for non-elite 54 yo at CrossFit St Paul, I injured my back when I lost form doing my 16th front squat with a 120+ pound bar. (More on CrossFit in a 2013 post I think). Clean and jerk and squats likely voided my PNBC warranty. That pain resolved in about 24 hours, and 48 hours later the discomfort is mild.

It must be noted PNBC's aggressive strengthening program doesn't make one completely invulnerable. (That's a joke.) I'll go easy for the next six weeks, then keep my free weights under 90lbs for the next six months and focus on reps.

After 2009 PNBC was acquired by a local healthcare enterprise; I suspect it's lost a bit of the old intensity. Sadly, their 2009 approach to managing back pain is still radical.

Update 12/24/2015 - 8+ years later.

Over the past 4 years I've had 2-3 back strains related to pushing the envelope while weight lifting, most recently on the dead lift. I don't think one can complain about this sort of thing! So far they've all resolved fairly quickly with nothing like the severe pain I once new. So far :-).

What works best for lower back pain

The surprising thing about this study is that anyone thought it was surprising …

What's the best Rx for lower-back pain?: Scientific American Blog 

We did an evaluation of high quality studies on the prevention of back problem episodes in adults [and] found that, surprisingly, exercise is the only intervention that works, and other popular interventions don't work," says Stanley Bigos, emeritus professor of orthopedic surgery at the University of Washington in Seattle, and lead author of the analysis published recently in The Spine Journal. .. 

… Exercises such as lifting free weights and doing leg and trunk lifts to fortify core muscles proved effective at staving off pain, Bigos says. The studies in the review focused mainly on exercises to build muscle strength and endurance – not intense cardio workouts, but Bigos says that speed walking, cycling, and other activities that increase heart rate and improve overall fitness also benefit back health.

Only an orthopedic surgeon could be surprised by this study.

My recollection is that exercise and fitness has been considered the best way to manage lower back pain for at least fifteen years. What’s a bit more controversial is how much strengthening is really needed (and thus worth paying for). When I finally decided to rehab my own back I opted for the extreme strengthening approach of a local team – the Physicians Neck and Back Clinic.

I suspect their regimen is far beyond anything Bigos looked at, but I think they’re probably on the right trail.

The pain is all in your head

Firstly, this excellent essay by Atul Gawande is a reminder of how cruel life can be.

Scratching through one's skull is an undeniable sign of way too much suffering.

Secondly, it's a story of how the understanding of perception is evolving ...

Annals of Medicine: The Itch by Atul Gawande for The New Yorker

...This may help explain, for example, the success of the advice that back specialists now commonly give. Work through the pain, they tell many of their patients, and, surprisingly often, the pain goes away. It had been a mystifying phenomenon. But the picture now seems clearer. Most chronic back pain starts as an acute back pain—say, after a fall. Usually, the pain subsides as the injury heals. But in some cases the pain sensors continue to light up long after the tissue damage is gone. In such instances, working through the pain may offer the brain contradictory feedback—a signal that ordinary activity does not, in fact, cause physical harm. And so the sensor resets....

The ideas aren't quite as novel as Gawande suggests. I recall fifteen years ago veteran physicians, with lots of experience with intractable pain and chronic fatigue, had begun to think the problems were "all in the patient's head". By which we meant, with intentional irony, that the problem was "malwiring" of the brain.

The good news is, the brain is plastic. We can't easily alter it directly, but we can slowly reprogram it through the mind. That's how the mirror-box therapies Gawande describes work, and presumably that's how exercise therapy works for chronic fatigue syndrome (albeit both imperfectly).

We'll get better at this 'rewiring by programmed experience' techniques, but we're also going to have to sometimes rewire directly -- with microfilament implants and with the grosser neurosurgical techniques sometimes used for intractable seizure disorders.

How to construct an emergency custom back support car seat for under $20

Imagine that you have been lying flat in the back of a van for almost 3 days.

True, your back is healing. On the other hand even a small head-on collision will fracture your neck, it's very uncomfortable, the ceiling is exceedingly dull, and the dog is smelly:

Clearly, inspiration is needed.

Experimentation shows that any time spent in a conventional car seat is a painful trip to acute muscle spasm. On the other hand, maintenance of exaggerated lumbar lordosis (curvature of lower back) and neck extension is well tolerated.

How can one transform a conventional bucket car seat into something that will support an upright posture for 1,500 miles of driving over about 8 hours a day for two days?

Well, it has been done. In fact, while sitting in my custom rig I healed more quickly than when lying flat on the rather uncomfortable van floor.

The total cost for the rig would be about $25. Since I already had the freezer insert and the neoprene wrap it cost me about $8 for the Walmart mini-boogie board [3]. (See photo below, it's about 24" tall.)

1. I adjusted the seat so that it was as close to a right angle as possible, with the base as flat as possible.


2. I placed the foam boogie board along the seat back to create a non-yielding seat back.


3. I removed the seat's neck protector as I found I needed more neck extension than the seat headrest allowed [2]


4. I inserted the 1" thick red hard plastic frozen picnic cooler [1] into the neoprene wrap and fitted it so the plastic spacer was either in the middle of my lumbar curve or just below the curve. This created a fixed exaggerated super-cooled [1] lumbar curve.


5. Every 2-3 hours we stopped the car. I walked until I'd loosened up, then attached my inline skates (I figured out how to do this while keeping my lordosis extended) and skated for 10-15 minutes with Kateva to keep the back as limber as possible.

And so I drove for two days. I was very careful to enter and exit laterally, so at no time did I reverse my lumbar lordosis.

When we finally arrived home, I exited without pain. I even fell a step at the neighbors and my back survived.

Next week I have my first appointment for back care in over 27 years of 1-2 times/year severe disabling acute back pain. It's time for me to get a serious lifelong exercise program in place so I don't have to do this one again.

I will be using my custom back support for a few days however, and when we do our next car trip I'll put the boogie board somewhere. The kids can use it in the pool anyway ...

[1] This is medically illegal. It will cause you to develop frostbite, skin and muscle necrosis, toxic shock and you will die. You should use a non-frozen item of similar size and shape.

[2] This will cause you to fracture your neck in a car accident. You will be paralyzed and on a ventilator, then you will die a slow death that will bankrupt your family.

[3] I wandered the aisles waiting for inspiration to strike, looking for something that would provide firm but lightweight back support. High impact styrofoam in a fabric cover was perfect. I just happened to set eyes on the mini-boogie board ...
PS. There's a bit of irony here. I first wrecked my back 27 years ago boogie-boarding with a full-sized board in Southern California. Maybe that's why I really chose this fix.

Update 7/7/08: I received a post skeptical of my enthusiasm for cold therapy vs. hot packs. I followed up with my new team at Physicians Neck and Back Clinics (profiled in the New Yorker in April 2002, they represent the "new wave" approach of aggressive exercise based rehab). They never use heat or hot packs. They use only cold therapy, though for them strength and flexibility are 90% of the solution. I suspect hot packs can be very helpful for some, but they're really out of fashion. I've only ever bothered with cryotherapy.

Update 3/4/09: I'm going to write a bit more on this topic in July of 2009, when I'm a year post event. I've done well for long enough though that I'm a cautious fan of the extreme core strengthening approach of Physicians Neck and Back Clinics. It might be overkill, but I wouldn't be surprised if it turns out to be about the right balance.

Update 8/1/10: I did the f/u post in Nov 2009, but forgot to backlink it here.

ED treatment of acute back pain - what's missing and why

[There's something messed up with how Scribefire and Blogger are formatting this post, but for the life of me I can't fix it! So, there are no real paragraphs. I'm going to forego use of Scribefire with FF3 until I sort this one out.]

I had the 2nd ambulance ride of my life recently.The ambulance was overkill. Four strong bodies, duct tape and a door would have been more appropriate, and cheaper too.

Alas there was no intermediate alternative. I was unable to stand or crawl with mere ibuprofen and canes, and that becomes a problem over time. Since nobody will prescribe narcotics and valium over the phone this left me with only one route to medical care -- a back board.

The ED got adequate control over the back spasms with modest doses of IV valium and morphine [1]. I was a pathetic sight hobbling out of the ED on two canes to lie flat in an emptied van, but six hours later, after continuous ambulation, I walked a mile without difficulty using a single cane as a psychological aid. I was on the way to rehab. [2]

I'll have a bit more to say in a later post on the pointless cost of this episode vs. the intelligent alternative, but this particular post is about three very simple things that the ED didn't do. I had them covered myself, but without them I'd still be in the hospital.

So these interventions matter. The important question is why did I have to take care of them?

Now I think I was the guest of a quite good rural ED, and I felt feel confident that ER doc who took care of me seemed confident and competent (and comely too!), so I suspect these are common omissions:

• a cold pack and a neoprene waist belt to provide continuous cold therapy to the acutely spasmed back
• two canes to enable ambulation
• a urinal to enable sleep at home
• (see more here)

The urinal is key for the first day or two at home, yet I had to keep reminding the staff that it needed to go with me.

The ED had no canes, but I could never have done my pathetic totter out of the facility without them. They did have a walker I could test my gait with, but a walker isn't designed to support body weight while in motion. They didn't think to train me on how to use a cane (I knew how), but any significant back pain requires days of cane use. (If your acute musculoskeletal back pain doesn't require a cane, do you really need an ED?)

Continuous cold therapy during the acute episode is an key part of most therapeutic recommendations. I realize reactions differ, but cold therapy is essential for me. I had to bring my own neoprene cold pack belt, and I had to request ice (they had no cold packs).

In the end everything worked, but acute back pain is hardly a rare ED event. Why didn't they have the key ingredients in place?

I'd like to see someone do a survey article on what percentage of EDs provide these 3 items on discharge, in addition to whatever else they do:

1. local cold therapy (an ace wrap and an Rx for a neoprene belt would do - total cost $4)
2. canes with usage instructions ($10 each at Walmart - crummy but effective)
3. a disposable urinal for men (free, since you keep the one you use in the ED).

My guess is that less than 10% of EDs meet this standard, and the result is a horrendous waste of money nationally.

So why hasn't the study been done? If it has been done, why aren't payors making these steps a part of their quality measures used to justify reimbursement? If this stuff isn't in the standard ED guidelines, then we have an even more interesting set of "why" questions.Understanding these "why" questions would tell us a lot of interesting things about health care and where money is spent.

[1] The cognitive effect of the "morphine" was so modest I wondered if it was saline placebo (which would have been fine really -- anything that works!). I think they were just doing small incremental dosing

[2] Once the pain is under some control, and improvement has begun, the rehab process has a certain appeal. Every day actions are a bit like mountain climbing, with the same need for concentration, precision, and planned motion. Also, the same sense of risk with error. It appeals to a certain twisted mind.

Innovations in back pain management: cold and colder packs

[Update: I had a more extensive post on the same topic in 2005, that one's more complete.]

Every bad back is bad in a different way. Mine puts me down fast, but recovers fast. The key for me is cold [1], cane, and motion. Slap the cold pack on within a minute of an outage, whip out the cane, slug back the ibuprofen, and get moving. (I swear by therapeutic inline skating on day 2, but that's a bit extreme.)

My fundamental accessory is the brilliant Tru-Fit neoprene/velcro wrap that holds one of the four cold packs we keep in the freezer. That patent was well deserved.

There's only one problem. Therapeutic cold packs aren't all that cold, and they're only good for about 20 minutes at a time. They're designed to be relatively safe for persons with impaired vasculature and sensation, particularly diabetics. On the other hand, picnic packs are uncomfortably hard and too cold, not to mention absolutely contraindicated for just about everyone.

So my latest innovation is to double 'em up. A small picnic pack goes on the outside of the pocket, a large therapeutic pack goes on the inside (against my back). The results is just right, and it lasts for over an hour (yeah, I know, you're supposed to use cold for 20 minutes -- I have a lot of experience with this).

Use at your own risk. I guarantee you will develop deep tissue freezing, secondary necrosis, massive muscle loss, disseminated infection, toxic shock, and massive stroke due to multisystem organ failure. You will fester in misery for 20 years draining your family's resources. Don't say you weren't warned.

The neoprene back wrap and other parts of John's acute back pain recipe

Most mortals have more than a few flaws in their design. By middle-age you know most of them. Among mine is a bad back, a familial disorder that first manifested 25 years ago when I body surfed into the shore of Huntington beach.

So beyond my mere medical experience, I have twenty years of personal experience with (mostly) non-neurological bad backs (the kind where something tears, there's bleeding, scarring and lots of muscle pain). As in drop to the floor and lie there trying to figure out how to reach the phone. Which is why I'll pass on some hard won knowledge today, with the canes at my side. Don't follow this advice without the approval of your physician; your back may differ. You might even have a serious medical problem, though most bad backs are like mine.

Here is what works for me, It's also pretty much what's in the current guidelines:

1. Cold packs. The miracle innovation here is the TRU-FIT Ice/Heat Back Wrap w/ Gel Pack. Stick a cold pack in it (you're supposed to use the cold packs designed for humans, not the frost-bite inducing packs for picnic units). Wear it. Rotate pack every 1-2 hours, so you need 3 packs. For me 2-3 days of continuous use is important. Diabetics and elderly need to be careful of cold damage. There is a weight related problem with cold packs. Fat is a great insulator (that's one of the reasons we deposit fat under our skin). The more fat you have, the less effective the cold pack is; it becomes harder to cool the deep tissues and restrict incoming blood flow. One might be tempted to use the picnic coolers (colder stuff), but you run the risk of necrosing superficial tissue, visit to the ICU, death, etc. America seriously does need a pill for obesity; I wouldn't mind one myself.

2. Canes. $22 at Walgreens. Swear by them. Good for getting off the floor and making it possible to ambulate fast. When you need to cough, you need the cane. I use two for 2 days typically, then 1 for a week or so.

3. Meds: tylenol and ibuprofen alternating for 2-3 days then as needed. Vicodin (tylenol + hydrocodone) if you have it is very valuable for the awful first night, but no more than 1-2 days of use. You need the Vicodin on hand; when this kind of back attack hits a trip to the doctor is inconceivable (way too much pain). By the time one can travel the Vicodin is no longer needed. I used to prescribe Flexeryl to patients and I suspect it works, but I don't use it myself.

4. Sleep: on a carpeted floor, maybe with one of those very thin inflatable outdoor camping mats. Not the inflatable beds, the mats used by serious hard core hikers. Keep extra cold packs in a nearby insulated container. Also meds, water bottle and, for men, a .. ummm ..."receptacle". You don't want to have to get up if you can help it!

5. Ambulation and exercise. There are religious wars around this; extension exercises are most popular now. I do whatever doesn't hurt too much and I walk as much as I can. I skate to relieve back pain, which is insane. However, if one can avoid falling, this works very well after day 3-4. A gym elliptical exercise machine is far safer and works in a similar fashion.
I start the gym, cane at my side, on day 3. Climbing stairs often works well for me, if the decent hurts a down elevator is handy. Basically if it hurts, I do something else.

Usually by day 5-7 I can do a fair bit of exercise. I don't run ever, but biking and skating can work. It if hurts I don't do it.

6. Course? Awful for about 12-24 hours. Bad for another day. By day 5-7, if no re-injury, feeling almost well. It takes 6 weeks to have a reasonably solid back. I try to avoid heavy lifting for 2-3 months but often do it earlier (heavy for me is 80lbs, I'm a wimp). If I'm exercising properly I've never hurt my back when lifting fairly heavy items properly (straight back lift). Sitting, on the other hand, is really tough on a back. I have an Aeron chair at work (legacy of startup days) and in the acute phase I lie on the ground part of the day, ambulate often, and do phone conferences while walking.

7. Prevention? It's all weight control and exercise, and a some basic back hygeine. Sitting is bad but unavoidable. Don't push things, even light things, bent over. I knew I was due for this episode because family obligations have messed up my exercise regimen. Weight training and stretching and aerobic non-impact. Running is a very bad idea for most bad backs.

The only new prevention thing I'm going to add is using the gel pack early when I've done something dumb -- before my back "goes out" in a big way. I'm hoping early action with ice, healing activity, and careful exercise will avert major ruptures.

Update 8/1/2010: Things got much tricker later. I changed my mind on what works.
