How Dr. Yasmeh helped a 71-year-old patient walk pain-free again.

By the time he came to LAOSS, our patient had organized his life around the one-block rule. The retired engineer used to walk the loop around his neighborhood — about a mile and a half — every morning. Over the prior 18 months, that loop had shrunk. First to half the route. Then to the end of his street. Then to one block, with a planned bench at the corner where he could sit until the pain in both legs let go. He described it as a deep, burning ache from the buttocks down the back of both thighs, sometimes with a pins-and-needles feeling in the calves. He had learned, without anyone telling him, to lean on the shopping cart at the grocery store — and he could walk an entire aisle that way, but not five steps without it.

This is the textbook description of neurogenic claudication, and it's the symptom signature of lumbar spinal stenosis. On exam he had a positive Romberg, mildly diminished sensation in the L5 distribution bilaterally, but — importantly — 5/5 strength throughout the lower extremities and intact reflexes. His MRI confirmed what the history predicted. The thecal sac was severely narrowed at L3-L4 and L4-L5 from a combination of ligamentum flavum hypertrophy, facet arthropathy, and mild disc bulging. Flexion-extension X-rays showed no listhesis and no instability — meaning the segments were tight, but they were not sliding.

Stenosis is one of the few spine diagnoses where conservative care has a long, honest runway, and we used it. We started with ten weeks of physical therapy weighted toward flexion-bias exercises — the recumbent bike, seated rows, supported forward-flexed walking on a treadmill with the handrails — because flexion opens the spinal canal a few millimeters and meaningfully reduces nerve compression in this patient population. He also began a careful trial of gabapentin, titrated slowly to 900 mg/day in divided doses, which softened the burning neuropathic component of his leg pain but didn't touch the underlying mechanical compression.

When PT and medication plateaued, we moved to a fluoroscopically guided transforaminal epidural steroid injection at L4-L5. He got about six weeks of meaningful relief — enough to walk three blocks and start sleeping through the night — and then symptoms returned. A second injection four months later produced a similar pattern: real benefit, but partial and time-limited. At that point we had a conversation about what came next. The decompression conversation is never urgent in a patient without progressive neurological deficit, but it is honest: when injections give you six weeks at a time and your walking tolerance is one block, you are paying a real quality-of-life cost. He told us he was tired of planning his day around a bench.

Three things made him a strong candidate for a straight decompression. First, his symptoms matched his imaging — neurogenic claudication, multilevel stenosis on MRI, and clear flexion-relief on history. Second, his flexion-extension films showed a stable segment with no spondylolisthesis, which meant we could remove the compressive bone and ligament without destabilizing him. Third, his goals were specific and modest — walk a mile, return to golf, sleep through the night.

We performed a two-level laminectomy at L3-L4 and L4-L5 with bilateral foraminotomy to open the lateral recesses and exiting nerve roots. Fusion was deliberately avoided. Fusing a stable segment in a 71-year-old adds operative time, blood loss, hardware cost, and a longer recovery — without a corresponding benefit when the pre-operative imaging shows no instability. The published literature supports decompression-alone in carefully selected patients without listhesis, and he fit that selection.

Stenosis surgery does not fix every patient — and any spine surgeon who tells you otherwise is selling something. Patients with severe pre-operative neurological deficits — significant numbness, real motor weakness, foot drop, balance loss from long-standing nerve compression — often have residual symptoms even after a technically excellent decompression. Nerves that have been compressed and ischemic for years do not always recover fully once the pressure is removed. The mechanical problem is fixed; the neurological one may not be.

This patient was selected, in part, because he was the favorable phenotype. His symptoms were pain-dominant, his strength was intact, his reflexes were intact, and his duration of severe symptoms was measured in months, not years. Patients who walk in with a foot drop and two years of progressive weakness need the same honest conversation in the other direction: we can decompress the nerve, but we cannot promise it will wake all the way back up. The right time to have that conversation is before surgery, not after.
