Objective       To study the clinical outcome of degenerative lumbar scoliosis accompanying spinal stenosis in elderly patients.       Methods      Thirty-seven patients (15 males and 22 females aged 57.6±5.8 years) with degenerative lumbar scoliosis

admitted to our hospital from January 2004 to January 2008

were retrospectively analyzed. Their Cobb angle and Oswestry disability index（ODI）were compared before and after operation and at the last follow-up time.       Results      All the patient included in this study were followed-up for 18.5±5.5 months. Their clinical symptoms and life quality were significantly improved after operation. The ODI was significantly higher before operation than after operation and at the last follow-up time (59.6±12.5 vs 34.6±8.6 and 36.3±6.8

P0.05). The Cobb angle was significantly larger before operation than after operation (25.3±5.7 vs 11.4±6.3

P0.05) with a correction rate of 84.5% and a bone fusion rate of 100%. No relevant complication such as vertebra fusion shift

intervertebral space collapse

and screw breakage occurred.       Conclusion      Combined posterior decompression and vertebral arch pedicle screw fixation fusion is one of the effective procedures for degenerative lumbar scoliosis accompanying spinal stenosis in elderly patients.
