Hospital Course:

This 63-year-old male veteran was referred to the clinic for worsening low back and bilateral leg pain that had been present for two years. He reported limited walking distance due to pain and was only able to walk about 50 feet before needing to rest. The patient had previously tried Gabapentin without relief.

Physical Examination:

The patient's BMI was noted to be 38 at the time of presentation. He had moderate flexion and extension limitation with lumbosacral pain on extension. Sensory, motor, and tendon reflexes were within normal limits. Orthopedic testing revealed facet loading and limited hip internal rotation and flexion bilaterally.

Diagnostic Studies:

Computed tomography showed suspected left foraminal disc protrusion at L4–5 and bilateral L4–5 and L5-S1 facet hypertrophy, but no stenosis. MRI revealed circumferential epidural fat at L5-S1 and grade III pathognomonic "Y" sign.

Treatment:

The patient underwent six sessions of flexion-distraction and high-velocity low amplitude manipulation to the lumbar and thoracic spine. Soft tissue manual therapy was performed on the hip external rotators bilaterally. He was instructed in lumbar end-range flexion, hip mobility exercises, and sciatic nerve glides. Re-examination at the seventh session showed no significant change.

Consultation:

The patient was cleared for a neurosurgery consult and opted not to pursue surgical intervention.

Discharge Instructions:

The patient was advised to continue with his current activity modification and exercise plan as tolerated. He was encouraged to maintain a healthy weight and manage his diabetes. The patient was advised that pain management may be necessary into the future.

Follow-Up:

The patient was to follow up with his primary care provider and request referral to an alternative specialist if needed.
