  目的:探讨严重脊柱畸形后路全脊椎截骨术后内固定棒断裂的原因及处理策略的选择.方法:对2003年06月至2011年06月进行后路全脊椎截骨术后随访过程中发现内固定棒断裂且临床资料完整的7例脊柱畸形患者进行回顾性分析.男4例,女3例.初次手术时年龄15-38岁,平均24.4岁.术前侧凸Cobb角17~81°,平均52.2°;后凸Cobb角60~113°,平均81°;冠状面上C7铅垂线距骶骨中线距离为0.1~2.4cm,平均0.4cm;矢状面上C7铅垂线距骶骨后上缘距离为0.3cm~9.1cm,平均3.7cm.

目的 对于晚期强直性脊柱炎(ankylosing spondylitis,AS)伴假关节形成的患者,如果伴发疼痛、矢状面畸形和或神经功能损害等表现,需行手术治疗.但是对于伴假关节形成的有症状的AS患者来说,最安全有效的手术治疗方法仍然存在争议.因此本研究的目的在于探讨经假关节行椎弓根截骨术(pedicle subtraction osteotomy,PSO)+前路融合术对于伴假关节形成的AS后凸畸
目的:比较徒手克氏针加叩击法和电钻驱动法在腰椎椎弓根螺钉置入中的准确性和安全性。方法:对157例行腰椎椎弓根螺钉内固定的脊柱侧凸患者术后行CT扫描。根据置钉方式分克氏针法置钉组和电钻驱动法置钉组。记录螺钉穿透骨壁的位置数目和距离。采用X2检验比较两组置钉精确性及凸侧与凹侧置钉精确性的差异。
