To observe the safety and efficacy of a minimally destructive decompressive technique without fusion in patients with lumbar stenosis secondary to degenerative spondylolisthesis. 30 patients with degenerative spondylolisthesis (DS) were consecutively managed by a single consultant spinal surgeon. All patients presented with neurogenic claudication secondary to DS. All patients were managed operatively with lumbar decompression utilising an approach technique of “spinous process osteotomy” (1). Briefly, this approach requires only unilateral muscle stripping with preservation of the interspinous ligament. A standard centrolateral decompression is then performed. Data consisting of VAS back and leg pain and ODI were collected pre and post-operatively.Purpose
