【摘要】 目的　研究USS椎弓根内固定系统应用于脊柱后凸畸形截骨矫治内固定的疗效。方法　根据后凸角度采用一次性多平面全脊椎截骨 ,应用USS椎弓根内固定系统固定 ,对后凸角度矫正率 ,截骨融合率 ,内固定结构稳定性进行随访统计。结果　 31例得到术后平均 12个月随访 ,术前脊柱后凸角平均 73°,术后后凸角平均 12° ,截骨融合率 96 77% ;后凸角矫正率为 83 5 6 % ;无一例发生断钉、断棒及联接结构松脱。结论　采用USS椎弓根内固定系统固定 ,增加了脊椎融合率 ,提高了后凸角矫正率 ,脊柱基本呈流线型恢复生理曲度 ;可早期离床活动 ,无须外固定。更多还原

【Abstract】 Objective To describe a method for the treatment of kyphosis with USS and evaluate its clinical effect Methods 31 patients with kyphosis were treated with one-stage total vertebral wedge-shaped osteotomy and USS for internal fixation.The follow-up period was 1 year.The clinical effect with the spinal column Cobbs angle(before operating and after operating)and the osteotomy confluence rate were observed.Results The preoperative Cobbs angle in 31 cases was in an average of 73° and postoperatively the angle in average was 12°;the average percentage of correction was 83.56%,the average percentage of osteotomy confluence was 96.77%.Conclusion The USS is a reliable internal fixation instrumentation for the treatment of kyphosis,for increasing the osteotomy confluence rate and improving the rate of correction.更多还原
