Protrusion of the posterior longitudinal ligament simulating herniated lumbar intervertebral disc.

Protrusion of the posterior longitudinal ligament simulating herniated lumbar intervertebral disc.

The most common cause of lumbar or sacral nerve-root compression probably is herniation of the nucleus pulposus. There are some patients with typical clinical-and even radiological-evidence of ne'rVe root compression, however, in whom no herniation is found at operation; instead the nerve root is compressed by a fold in the posterior longitudinal ligament, and, when this is excised, there is

Spontaneous Regression of Herniated Lumbar Disc with New Disc Protrusion in the Adjacent Level

Spontaneous regression of herniated lumbar discs was reported occasionally. The mechanisms proposed for regression of disc herniation are still incomplete. This paper describes and discusses a case of spontaneous regression of herniated lumbar discs with a new disc protrusion in the adjacent level. A 41-year-old man was admitted with radiating pain and numbness in the left lower extremity with ...

Posterior epidural migration of herniated lumbar disc fragment.

OBJECT Posterior epidural migration of a free disc fragment in the lumbar region is a very rare condition that has only been reported in isolated cases to date. Patients with this condition present with radiculopathy or major neurological deficits. Difficulties in diagnosis and the choice and timing of surgical treatment are important in these cases. In this clinical case series, features of ca...

Herniated lumbar disc.

INTRODUCTION Herniated lumbar disc is a displacement of disc material (nucleus pulposus or annulus fibrosis) beyond the intervertebral disc space. The highest prevalence is among people aged 30 to 50 years, with a male to female ratio of 2:1. There is little evidence to suggest that drug treatments are effective in treating herniated disc. METHODS AND OUTCOMES We conducted a systematic review...
