后路半椎体切除钉棒系统内固定治疗先天性脊柱后凸

目的评价后路半椎体切除钉棒系统内固定治疗先天性脊柱后凸畸形的疗效。方法采用后路半椎体切除或椎体截骨经椎弓根内固定术治疗3例患者,术后支具固定6～12个月,通过对比术前术后X线片评估患者躯干平衡和失代偿情况。结果术前后凸Cobb角平均102°,术后为21°,3个月后为23°,所有患者外形正常,躯干平衡良好,未发现失代偿现象。结论对先天性脊柱后凸畸形进行后路半椎体切除或截骨椎弓根钉棒矫形可矫正和控制冠状面和矢状面畸形。

Hemivertebra resection via posterior approach and transpedicular intra-fixation for correction of congenital kyphosls

Objective To assess curative effects of hemivertebra excision with transpedicular instrument for the congenital kyphosis.Method The 3 cases were managed surgically with hemivertebra excision posterioroly and transpedicular instrumentation.Holo-vest were applied in each patients for 6-12 months postoperatively according to radiographic demonstration and clinical examination.The status of trunk balance and decompensation were evaluated.Result Mean cobb angle of the main curve was 102° before operation,21° after operation,and 23° later 3 monthes after operation.Trunk imbalance or decompensation were not found in this study.Conclusion Posterior resection of the hemivertebra and fixation with transpedicular screw is suibable to treat congenital kyphosis and could obtain excellent correction and control kyphosis in the frontal and saggital planes.
