Surgical Management of Degenerative Spinal Stenosis

Posterior spinal arthrodesis is commonly employed in patients with spinal stenosis, although certain patients may require additional interbody support applied either anteriorly or posteriorly. Although autograft, allograft, and recent biologic agents such as rhBMP-2 are available for arthrodesis, meticulous fusion technique is still essential for a successful result. Posterior pedicular screw and rod fixation remain the most commonly employed internal fixation for the treatment of spinal stenosis since it allows for stabilization of instability, correction of deformity, and improved arthrodesis success. This article outlines the etiology, pathogenesis, current treatment options, and various surgical techniques available for the treatment of spinal stenosis.
