经后路半椎体切除固定治疗儿童先天性脊柱侧凸

目的评估经后路利用蛋壳技术切除半椎体,应用椎弓根钉棒系统固定临近椎体治疗先天性脊柱侧凸的临床效果。方法回顾分析2006年6月至2009年1月收治的半椎体引起的先天性脊柱侧凸畸形患者17例,其中男12例,女5例,年龄5.5-11.3岁,平均8.4岁。均为单一的完全分节的胸腰段半椎体。取后正中切口,应用蛋壳技术切除半椎体,椎弓根钉棒系统临近节段固定。比较手术前后患者站立位身高、侧凸Cobb角。结果手术时间46 h,平均4.5 h。术中出血400-800 mL,平均500 mL。所有患儿顺利完成手术,术后1例发生1枚椎弓根钉拔出,进行了二次手术调整。其他病例均无并发症发生。身高平均增加（6.47±2.06）cm,侧凸Cobb角由术前（50.94±18.75）°减小到术后（18.12±6.87）,°矫正率为64.4%。随访时间28-40个月,平均30个月,矫正效果满意。结论经后路利用蛋壳技术切除半椎体,应用椎弓根钉棒系统内固定治疗先天性脊柱侧凸手术矫正效果满意。

Hemivertebra Resection Via Posterior Approach and Egg-shen Technology for Children Congenital Kyphoscoliosis

Objective To evaluate the clinical effects of hemivertebra resection via posterior approach and egg-shell technology for children congenital kyphoscoliosis.The nearby vertebras were fixed by pedicle screw and rod system.Methods From June 2006 to January 2009,17 congenital kyphoscoliotic cases caused by fully segmented hemivertebra were treated in our department.All cases were analysed retrospectively.There were 12 males and 5 females among them,the average age was 8.4 years old.The hemivertebras were resect...
