目的：比较青少年腰椎间盘突出症(adolescent lumbar disk herniation,ALDH)患者与性别、年龄匹配正常青少年的矢状面脊柱-骨盆形态,探讨ALDH发生的潜在影像学风险因素。方法：2004年3月-2012年3月期间在我科接受手术治疗的青少年腰椎间盘突出症患者共23例。包括男14例,女9例；年龄12-18岁。年龄及性别匹配正常青少年40例作为对照组。其中男24例,女16例,年龄13-18岁。在站立位全脊柱侧位X线片上测量以下矢状面参数：(1)胸椎后凸角(thoracic kyphosis, TK)：T5椎体上终板到T12椎体下终板的Cobb角；(2)腰椎前凸角(lumbar lordosis, LL)：即L1椎体上终板到S1椎体终板的Cobb角；(3)矢状面平衡(sagittal vertical axis, SVA)：骶骨后上缘与C7铅垂线的距离；(4)骨盆投射角(pelvicincidence,PI)：骶骨终板中点与双侧股骨头中心连线中点所连直线与骶骨终板垂线形成的夹角；(5)骨盆倾斜角(pelvic tilt, PT)：骶骨上终板与水平线之间的夹角；(6)骶骨倾斜角(sacral slope,SS)：双侧股骨头中心连线的中点与骶骨上终板中点的连线与股骨头轴线之间的夹角。两组矢状面脊柱-骨盆参数的比较采用t检验。

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。
