Lumbar Pain, Anticoagulation, and a Request for HVLA
Mr. D is a 62-year-old retired teacher with a 10-year history of mechanical low back pain. Three weeks ago he lifted landscaping stones and developed midline lumbar pain radiating to the left buttock, rated 6/10 with flexion and prolonged sitting. He denies bowel or bladder dysfunction, saddle anesthesia, fever, or progressive weakness. Eight months ago he had a provoked left leg deep vein thrombosis and has taken apixaban 5 mg twice daily since; his last dose was 14 hours ago. He also takes lisinopril 20 mg daily and naproxen 500 mg twice daily as needed, which he has used most days this week. Examination shows lumbar paraspinal hypertonicity, tender points at L4–L5 bilaterally, negative straight-leg raise, 5/5 strength throughout, and 2+ symmetric reflexes. Vitals are normal. Platelets are 214,000/µL, creatinine 1.0 mg/dL, and eGFR 78 mL/min/1.73 m². He asks for 'the cracking adjustment' that helped him five years ago. Your clinic has a standard OMT table and no fluoroscopy.
1. What OMT approach would you recommend, and which specific techniques or forces would you avoid? Explain your reasoning.

First, I would screen for red flags: the absence of saddle anesthesia, bowel or bladder dysfunction, fever, progressive weakness, and normal reflexes and strength makes cauda equina, infection, and malignancy unlikely. The main safety issue is bleeding risk: he takes apixaban and has been using naproxen most days, which increases gastrointestinal and procedural bleeding risk. I would avoid lumbar high-velocity, low-amplitude (HVLA) thrust because of the anticoagulant plus NSAID, and I would not use forceful articulatory techniques. Instead, I would use gentle indirect and soft-tissue approaches: muscle energy, strain-counterstrain, myofascial release, and gentle articulatory mobilization. These can reduce paraspinal hypertonicity and pain without a thrust. I would also stop naproxen and discuss acetaminophen and topical therapy, because continuing an NSAID with apixaban is a medication-safety problem independent of OMT. I would document the risk-benefit discussion and obtain consent. OMT should be part of a plan that includes activity modification and physical therapy; if symptoms worsen or neurological signs appear, I would reassess rather than proceed.
2. The patient insists on HVLA 'because it worked before' and offers to sign a waiver. How do you respond, and what do you document?

I would not perform HVLA simply because he signs a waiver. A waiver does not eliminate the clinical risk of a thrust while he is anticoagulated and using an NSAID. I would explain in plain language that the concern is bleeding into the muscle or spine, not that he is 'not allowed' to choose care. I would offer the indirect techniques again, plus physical therapy and analgesic optimization, and explain what improvement we expect. I would explore his goals: if he wants a specific 'pop,' I would clarify that the pop is not required for benefit. If he declines all OMT, I would document informed refusal and continue conservative care. Documentation should include the bleeding risk, the alternatives offered, his preference, the fact that HVLA was withheld for safety, and that he understood. I would not document a waiver as if it made the technique safe. If he remains insistent, a second opinion or physiatry referral is reasonable.
3. Two days later, he sends a portal message reporting saddle numbness and no urination since yesterday. What is your immediate action and why?
Read the worked answer
These are red-flag symptoms of cauda equina syndrome. I would call him immediately, tell him to go to the emergency department now, and not perform OMT. I would arrange urgent evaluation with a focused neurological exam, post-void residual, and emergent lumbar MRI. The combination of saddle anesthesia and urinary retention is a surgical emergency until proven otherwise; delay can cause permanent deficit. I would document the call, the advice given, and the time. In the emergency department, I would communicate directly with the emergency physician and request MRI and spine surgery consultation. If he cannot arrange transport, I would arrange emergency medical services. This is not a case for watchful waiting or for adjusting OMT.
