经后路全椎体切除矫正僵硬性脊柱后凸或侧后凸的初期临床报道

目的探讨经后路全椎体切除技术治疗僵硬性脊柱后凸或侧后凸畸形的手术技术并评估其临床效果。方法回顾性分析2004年10月-2006年7月，采用单纯后路全椎体切除技术治疗的12例僵硬的脊柱后凸或侧后凸患者。术前后凸Cobb角平均68°；合并侧凸者平均76°。以加压-撑开-开放-闭合矫形力获得矫形。结果后凸及侧凸矫正率分别为77．6％和66．7％，均获得满意的躯干平衡。随访时间为6-12个月，无内固定松动或断裂发生。结论在脊髓可耐受的范围内，全椎体切除术为脊柱全方位的矫形提供机会，可作为常规手术技术的补充手段。

Posterior total vertebral resection correct rigid kyphosis or kyphoscoliosis——clinical report of initial stage

Objective To discuss the operative technique and evaluate clinical outcomes of posterior total vertebral resection in treatment of rigid kyphosis or kyphoscoliosis. Methods A retrospective study was made involved in 12 cases (from October 2004 to July 2006) with stiffness kyphosis or kyphoscoliosis, and it was treated by single posterior total vertebral resection. Preoperative mean Cobb' angles of kyphosis was 68° and scoliosis was 76°. Compression, Distraction, Opening and Closing forces were combined to correct the deformity. Results The preoperative deformities in the sagittal and coronal plane were corrected and showing a immediate postoperative correction rate was 77.6% and 66.7%. At the final 6 to 12 months followed-up, no instrumentation failure was observed. Conclusion Posterior total vertebral resection provide the chance of deformities corrected sufficiently and maintain no more distraction or kinked of spinal cord. The operative procedure can only be supplemental technique of routine wedge osteotomy or anterior approach operation in the treatment of spinal deformity.
