椎弓根钉置入并后路半椎体切除修复胸腰椎半椎体畸形前后Cobb角的变化

背景:半椎体畸形是先天性脊柱侧后凸最常见的原因,半椎体切除可以直接去除致畸因素,是较理想的治疗方法.目的:观察和评价经后路Ⅰ期半椎体切除,并椎弓根钉置入内固定治疗胸腰椎体半椎体畸形引起的前后Cobb角的变化,来评价治疗脊柱侧后凸畸形的效果.方法:纳入2008/2010在无锡市第二人民医院骨科住院的11例由单个半椎体引起侧后凸畸形的青少年患者,均经Ⅰ期后路半椎体切除及椎弓根钉内固定修复.结果与结论:患者随访1.0~2.0年,术后站立位全脊柱正侧位X射线片示冠状面Cobb角由修复前的(49.2±12.8)°改善至(16.5±5.8)°,平均矫正率达66.5%,矢状面Cobb角由修复前的(35.7±6.2)°改善至(14.1±1.9)°,平均矫正率达60.5%.终末随访时冠状面Cobb角(19.0±5.8)°,丢失2.8°;矢状面Cobb角(14.4±1.9)°,无明显丢失.且在随访过程中未发生神经系统损伤、感染及内固定失败等并发症.说明经后路Ⅰ期半椎体切除,椎弓根钉内固定修复半椎体畸形所引起的脊柱侧后凸畸形矫形效果满意,丢失率低,融合良好.

Cobb angle changes in hemivertebra malformation patients before and after pedicle screw implantation combined with posterior hemivertebra resection

BACKGROUND: Hemivertebra malformation is the most common cause of congenital kyphoscoliosis. Hemivertebra resection can directly remove teratogenic factors, which is an ideal treatment method. OBJECTIVE: To observe the Cobb angle changes before and after posterior hemivertebra resection and pedicle screw internal fixation for the treatment of hemivertebra malformation so as to evaluate the treatment effect on kyphoscoliosis malformation. METHODS: Eleven adolescent patients with kyphoscoliosis malformation c...
