The results of decompression and instrumented fusion with pedicular screw plate system in degenerative lumbar scoliosis patients with spinal stenosis: a prospective observational study.

OBJECTIVE: To study pain relief curve correction, and functional outcomes after decompression and instrumented arthrodesis in degenerative lumbar scoliosis patients with spinal stenosis.

MATERIAL AND METHOD: Thirty-one degenerative scoliosis patients with symptom of spinal stenosis who underwent decompression and fusion with pedicular screw plate instrumentation and completed at least 2-year follow-up were included in this study Functional outcomes were obtained using Oswestry Disability Index (ODI) and Roland Morris score. The VAS pain relief walking ability and curve correction were collected as a result of the surgery.

RESULTS: Average age of the patients at the time of surgery was 64.87years (range, 50-87years) and mean follow-up was 32 months (range, 24-60 months). There was significant improvement in all outcome parameters including pain scales, walking ability, ODI, and Roland Morris score (p < 0.05) Five patients had major complications with two cases requiring re-operation.

CONCLUSION: Degenerative scoliosis with spinal stenosis is a complex spinal disease that requires decompression and stabilization procedures. Wide decompressive laminectomy and instrumented arthrodesis with pedicular screw plate system provided satisfied outcome included pain relief and functional restoration.
