【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　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 ,对 31例接受截骨矫治内固定治疗的患者进行随访分析。结果　 31例得到术后平均 1 2个月随访 ,术前脊柱后凸角平均 73° ,术后后凸角平均为 1 2°,截骨融合率 96 77% ,后凸角度矫正率为 83 56 %。无一例发生断钉、断棒及联接结构松脱。结论　USS椎弓根内固定系统具有内固定坚固、稳定 ,可早期离床活动 ,无须外固定的优点 ,使脊柱基本呈流线型 ,恢复生理曲度更多还原

【Abstract】 Objective To introduce a method to treat kyphosis with USS and evaluate its clinical effect Methods 31 patients with kyphosis were treated with"one stage total vertebral wedge shaped osteotomy"and fixed with USS.The follow up time was 1 year.The clinical results including the spinal column Cobb (before and after operation) and the osteotomy fusion rate were observed.Results 31 patients were followed up with average 12 months.The average Cobb angle of kyphosis was 73° before operation and 12° after operation.The average correction rate of kyphosis was 83 56% and the average fusion rate of osteotomy was 96 77%.No break of rod and nail and loose of connection occurred.Conclusion The USS is the reliable internal fixation instrumentation for the treatment of kyphosis.更多还原
