Improvement effect of low back pain with microendoscopic decompression for lumbar spinal stenosis: Comparison with degenerative spondylolisthesis and pattern of neurological disorder

Abstract

Sixty–five patients (45 male, 20 female; mean age: 71.7 ± 0.9) who under­went microendoscopic muscle preserving interlaminar decompression for lumbar spinal stenosis (LSS) were classified according to degenerative spondylolisthesis and pattern of neurological disorder. We estimated concerning clinical results and association between low back pain (LBP) and lumbar lordosis (LL). Postoperatively, leg symptom as well as LBP significantly improved in all groups. The improvement of LBP was significantly correlated with the increase of LL. Lumbar decompression for LSS may improve LBP and the lumbar alignment regardless of spondylolisthesis and pattern of neurological disorder.
