目的 :观察和评价由单个先天性半椎体引起的侧后凸畸形经一期后路半椎体切除及节段矫形内固定的初期手术效果。对象与方法 :对 10例由单个先天性半椎体引起的侧后凸畸形患者进行回顾性分析。年龄在 8～ 14岁之间 ,均经一期后路半椎体切除及节段性矫形内固定。随访 6个月～ 2年 (平均 1年 2个月 )。术前、术后及随访时摄站立位脊柱全长正侧位片进行观察。结果 :10例患者术前均有侧后凸畸形。术后侧凸角度由平均 69°改善至 2 8° (矫正率 60 %) ;后凸畸形由术前的平均 48°矫正至平均 19°。随访获初步或坚强融合 ,无神经系统损伤、感染及内固定失败等并发症发生。结论 :由先天性半椎体所引起的脊柱侧后凸畸形可经一期后路半椎体切除和节段矫形内固定而获得满意的矫形效果。手术适应证为由胸椎或胸腰段半椎体畸形所引起的青少年患者的结构性侧后凸畸形。
OBJECTIVE: To observe and evaluate the initial surgical results of hemivertebra resection and segmental internal fixation caused by a single congenital hemivertebra after one-stage posterior kyphosis. Objects and Methods: Ten patients with kyphosis caused by a single congenital hemivertebra were retrospectively analyzed. Aged between 8 to 14 years old, after a period of posterior hemivertebra resection and segmental orthotic fixation. Patients were followed up for 6 months to 2 years (average 1 year and 2 months). Preoperative, postoperative and follow-up position of the spine full-length orthopnea was observed. Results: Ten patients had kyphosis before operation. Postoperatively, the angle of scoliosis was improved from 69 ° to 28 ° (correction rate 60%). The kyphosis was corrected from an average of 48 ° preoperatively to an average of 19 °. Follow-up was a preliminary or strong fusion, no nervous system damage, infection and internal fixation failure and other complications. CONCLUSIONS: The kyphotic kyphoscoliosis caused by congenital hemivertebra can be satisfactorily corrected by a posterior hemivertebra resection and segmental internal fixation. The surgical indications are structural kyphosis of adolescent patients caused by hemivertebra deformity in the thoracic or thoracolumbar region.
