The goal of decompressive laminectomy is to relieve pressure on the thecal sac and exiting nerve roots, while preventing instability. It is a technically demanding operation because of ...

Note the central canal stenosis at the L3-L4 disk level. Contrast the two axial scans - in the upper scan one can clearly visualize the CSF (which is bright) and the nerve roots of the cauda equina ...

Within the surgical group, those with thecal sac compression of one-third or greater showed the greatest improvement and the highest treatment effect.

Within the surgical group, those with thecal sac compression of one-third or greater showed the greatest improvement and the highest treatment effect.

Progressive lower back pain, paraplegia, and urinary incontinence subsequently developed. Magnetic resonance imaging (MRI) revealed a lesion of the thoracic spinal cord and thecal sac; a biopsy ...

Radiologically disc extrudes into the spinal canal, significantly compressing the exiting nerve root and thecal sac. Am I too old for surgery or young for surgery?

A York County jury has awarded $23.87 million to 58-year-old James Spangler, who suffered serious injuries after a spinal surgery.

Perhaps because of gravitational effects, these lesions typically occur in the dorsal lower-thoracic to lumbar spine (Fig. 2). Nerve roots, cauda equina, nerve root sleeves and the fundus of the ...

A Kerrison rongeur is used to remove the thinned lamina, carefully decompressing the spinal canal. The ligamentum flavum lies between the lamina and the thecal sac.

Note the severe central canal stenosis at the L3-L4 disk level. Contrast the two axial scans - in the upper scan one can clearly visualize the CSF (which is bright) and the nerve roots of the cauda ...
