Mixter and Barr reviewed spinal masses previously labeled cartilaginous tumors of the intervertebral disc. They asked whether these lesions were true neoplasms or ruptures of the disc with herniated nucleus pulposus. The paper correlates the clinical picture of sciatica and cord compression with a mechanical disc lesion treatable by surgery.
When a patient with sciatica fails appropriate orthopedic treatment, think mechanical disc rupture, not just strain or sacro-iliac disease. This paper reframed a whole category of spinal masses. Lesions surgeons had been excising as chondromata were, on histology, herniated nucleus pulposus and annulus fibrosus.
The diagnostic workflow they describe still echoes today: elevated CSF protein with few cells, a myelographic block, disc space narrowing on x-ray, and a level-dependent neurologic exam. Remember the level rule. Cervical cord compression gives spasticity, hyperreflexia, and Babinski, while cauda equina compression gives absent reflexes and radicular pain.
As a case series of 25 patients from a single institution, the evidence is descriptive, but its correlation of pathology, imaging, and surgical outcome is what connected disc herniation to sciatica as a treatable surgical disease.
