Abstract

Abstract:

Objective To investigate the feasibility of the unilateral laminotomy for bilateral decompression (ULBD) in the treatment of degenerative lumbar spinal stenosis by anatomical study. Methods 10 adult formalin-fixed spine corpse specimens were selected,then the ULBD were performed with the posterior ligaments complex almost intact.CT scans were performed,and the parameters including the maximum anterior-posterior diameter the maximum transverse diameter,and the vertebral spinal canal area were detected before and after operation. Results Compared with before operation,the maximum anterior-posterior diameter and the maximum transverse diameter and the vertebral spinal canal area of corpses after operation were increased(P<0.01). Conclusion With the posterior ligaments complex almost intact,the ULBD could enlarge the lumbar spinal canal and decompress the nerve effectively.

Key words: unilateral approach bilateral decompression, degenerative lumbar spinal stenosis, minimal invasive spinal surgery
