后路椎管减压融合矫形椎弓根钉内固定治疗Aebi1型退变性脊柱侧凸

目的 探讨后路椎管减压融合矫形椎弓根钉内固定治疗Aebi 1型退变性脊柱侧凸的临床疗效。方法 回顾性分析自2007-02-2012-01收治的21例Aebi 1型退变性脊柱侧凸,采用后路椎管减压融合矫形椎弓根钉内固定手术治疗,随访19-26个月,平均22.3个月,观察JOA评分改善率、VAS评分以及侧凸Cobb角和腰椎前凸角矫正角度等指标进行疗效评价。结果 本组手术过程均顺利,随访期间观察VAS评分、JOA评分改善率、侧凸Cobb角和腰椎前凸角等指标,并在术后1、6、12、18个月分别进行评价,各项数据与术前比较差异均有统计学意义（P〈0.05）。结论 彻底减压、合理选择融合节段、提高融合率、适度矫形重建腰椎力学平衡是成功治疗Aebi 1型退变性脊柱侧凸的关键。

Posterior decompression,instrumentation and fusion for Aebi type 1 degenerative scoliosis

Objective To observe the clinical results of posterior decompression, instrumentation and fusion for Aebi type 1degenerative scoliosis. Methods A retrospective analysis was performed for 21 patients with Aebi type 1 degenerativescoliosis undergoing posterior decompression and fusion with pedicle screw system from February 2007 to January 2012. Allpatients received a mean follow-up of 22.3 months （range： 19-26）. The postoperative outcomes were radiologically evaluatedwith VAS and JOA scale, Cobb angle and lumbar lordosis angle. Results All the surgeries were successful, and the patientsrecoverd well. The patients were followed up and ebaluated at postoperative 1, 6, 12, and 18 months, to observe the clinicalefficacy, including the VAS and JOA scale, Cobb angle and lumbar lordosis angle. All these indicators had statisticallysignificant between preoperation and post-operation （P 〈0.05）. Conclusion Complete decompression, a reasonable choice offusion segments, improvement of fusion rate and moderate lumbar spine orthopedic reconstruction mechanical equilibrium arekeys to successful treatment of Aebi type 1 degenerative scoliosis.
