ABSTRACT
The purpose of this study is to report our experience with posterior dynamic stabilization, using an interspinous distracter that avoids excessive lumbar spine instrumentation, tolerating the segmental movement without foraminal conflict and preserving the adjacent segment. Twenty-nine patients with ages ranging from 48 to 70 [mean 56 years] underwent surgery using this device. All patients had low back pain that radiated to the lower limb in 21 cases. The follow-up period ranged from 6 to 12 months [mean 9 months]. Majority of patients showed outstanding results with relief of their symptoms. Interspinous distracter insertion is a safe and reliable tissue sparing technique that restores function by stabilizing the spine and maintaining the foraminal height, the natural functional anatomy and dynamism. It offers an alternative to rigid stabilization of lumbar stenosis with mild to moderate instability. Basic knowledge of spinal motion and careful selection of the patients is indispensable prior to its use
