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后凸畸形患者的手术疗效.材料和方法 回顾性分析7例伴胸腰段假关节形成的AS后凸畸形患者的临床结果.其中,男性6例,女性1例,平均年龄41.7岁.所有患者诉有背痛.影像学检查提示所有患者脊柱假关节部位都存在广泛的、累及三柱的椎间盘-椎体破坏.术前全脊柱后凸角(global kyphosis,GK)平均为75°(37°-114°),且假关节均位于顶椎水平.术前3例患者发生神经功能不全损害(Frankel评分D级).所有患者术前均一期在假关节水平行PSO术,二期行前路融合术.平均随诊时间38个月(24-59月).所有患者在术前、末次随诊时行视觉模拟量表(visual analogue scale,VAS)评分,并进行比较.
