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 64.87 years (range, 50-87 years) 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.
