A prospective cohort study was carried out looking at the functional outcome and post-procedure translational segmental instability after multi-level lumbar decompression using a Hinge osteotomy technique. The Hinge osteotomy technique involves unilateral subperiosteal muscle dissection with osteotomy of the base of the spinous processes thereby preserving the integrity of the posterior elements. The objective of this study was to demonstrate the results of this technique clinically and radiologically.Study Design
