Spinal stenosis is narrowing of the spinal canal or foramen in the neck or back usually from degenerative changes such as bulging discs, arthritic facet joints, bone spurs and redundant or calcified ligamentum in the spine. This causes compression of the spinal cord and/or nerve roots resulting in back or neck pain that radiates into the arms or legs, as well as numbness and tingling sensations. The initial treatment also includes medications and therapy followed by spinal injections. Surgical treatment of spinal stenosis focuses on decompression of the compressed nerve roots by laminectomy (removing the spinal lamina) and arthritic bone spurs. This can be done in a minimally invasive fashion with excellent results. Patients have 80-90% relief of their radiating pain.
