The purpose of this study was to clarify which type of low back pain in patients with degenerative spondylolisthesis could be improved by Graf stabilization. Subjects consisted of 46 cases of degenerative spondylolisthesis who had undergone surgery with Graf stabilization. As a control group, 42 cases of degenerative spondylolisthesis who had undergone surgery without Graf stabilization were used. The effects of Graf stabilization compared with the control group were as follows; ①a decrease in the frequency of persistent low back pain, ②prevention of progression of % slippage, ③decrease in mobility, ④the possibility of complications occurring, and ⑤no effects with regards to the degree of persistent low back pain, recurrence of leg symptoms, and JOA scores.
