Objective:
To study surgical techniques for degenerative lumbar scoliosis associated with lumbar stenosis and evaluate their clinical significane.
Methods:
Thirty-two patients with degenerative lumbar scoliosis associated with spinal stenosis were treated by techniques of posterior lumbar interbody fusion or posterolateral fusion and pedicle screws. There were 18 male and 14 female with 56.8 years old on the average (ranging from 49 to 75 years). There were no evident change of lumberlordosis in 15 cases, and lumber lordosis were obvious loss associated with lumbar subluxation in 17 cases. The correcting, the improvement of back and leg pain, complications and followed-up results were analyzed retrospectively.
Results:
Thirty-two cases were followed-up for 6 to 39 months (the average time of 13 months). The average correction rate of scoliosis was 58.0% and the rate of pain relief was (80.2 +/- 5.8)%. There were two cases of dura sac laceration, two cases of nerve roots injury and a case of pseudoarthritis. During followed-up, correction rate and height of disc spaces were not lost. Shift of interbody cages were no displaced; all the internal fixation got well fusion and the rate of fusion for the bone graft was 96.9%.
Conclusion:
Posterior pedicle screws combined with interbody fusion or posterolateral fusion is a safe and effective surgical treatment for degenerative lumbar scoliosis associated with lumbar stenosis.
