单纯后路短节段内固定治疗青壮年胸腰段骨折的中长期疗效观察

目的]回顾分析青壮年胸腰段爆裂骨折行单纯后路短节段椎弓根螺钉固定治疗的临床及影像学特点,探讨其临床疗效。方法]2002年6月～2006年4月,对54例青壮年胸腰段爆裂骨折采用后路短节段椎弓根螺钉固定治疗,不行后路植骨,并于术后12～20个月行内固定装置取出。资料完整、得到随访的32例。通过X线片,测量包括Cobb′s角,伤椎上下终板成角及伤椎椎体前缘高度比参数,分析手术前后不同时间的伤椎局部变化情况,并采用VAS(visualanalogscale,VAS)疼痛指数评价病程中腰背痛程度。结果]术后32例获得随访,随访时间36～56个月,平均43个月。内固定术后复位满意,疼痛缓解明显,椎弓根螺钉断裂4例。随访期间,伤椎椎体高度和伤椎上下终板成角丢失不明显(P0.05),Cobb′s角有一定丢失(P0.05),疼痛程度无明显变化。结论]对于青壮年,单纯后路短节段椎弓根螺钉固定能提供良好复位和高度维持,术后取出内固定装置,可恢复局部运动功能。
