摘　　要：目的：探讨后路半椎体切除、经椎弓根内固定治疗小儿先天性半椎体畸形的临床疗效。方法：2003年12月-2008年12月，采用后路半椎体切除、经椎弓根内固定治疗先天性半椎体畸形的小儿12例，术前Cobb角58°-28°，平均39．5°。术后3、6、12、24个月复查x线片，评估手术前后患儿的矫形效果和失代偿情况。结果：术后Cobb角平均为14．5°，矫形率64．1％。患儿躯干平衡良好，未发现失代偿现象。1例术后出现神经根刺激症状。结论：半椎体侧弯畸形在形成结构弯之前，采用后路半椎体切除、经椎弓根内固定手术治疗小儿先天性半椎体畸形，可以矫正和控制畸形。Objective：To investigate the clinical results of posterior hemivertebra resection with trans pedicular instrumentation. Methods：From Dec. 2003 to Dec. 2008, 12 consecutive cases of young children with congenital hemivertebrae deformation were managed surgically with hemivertebra resection posterioroly and transpedicular instrumentation. Mean age at time of surgery was 6.4 years （4 10.2 years）. Halo vest was applied in each patient for 6 months postoperationly. Mean Cobb angle was 39.5° （28°- 58°） before surgery. At 3,6,12 and 24 months postoperationly plain film were undertaken. According to radiographic demonstration, the status of orthopedic results and decompensation were evaluated. Results：Mean Cobb angle was 14.5° after surgery. Correcting rate was 65.6%. Trunk imbalance or decompensation was not found in this group. There was one incidence of neurodynia. Conclusions：Posterior hemivertebra resection with transpedicular screws al lows for early intervention of hemivertebrae in young children, which should be performed before the occurring of secondary structural changes. The spine deformity can be corrected and controlled.
