摘要 目的探讨在椎弓根螺钉固定的基础上采用三种不同的椎间融合法治疗崩裂性腰椎滑脱症的疗效。方法自2001年12月至2005年10月手术治疗崩裂性腰椎滑脱症56例并将其分为三组。A组22例,采用椎弓根螺钉固定后用单枚Cage加1枚自体骨块椎间融合术。B组16例,采用两枚Cage椎间放置融合术。C组18例,采用单枚Cage椎间斜置。对三组的手术出血量、椎间骨融合、滑脱的复位、椎间隙高度的恢复及临床疗效进行分析。结果随访8~54个月,平均22月。根据Nakai疗效评定标准:A组优12例、良10例;B组优8例、良7例、可1例;C组9例、良8例、可1例。在术中出血、滑脱的复位、椎间隙高度的恢复方面三组无显著的差异。而椎间骨性融合方面,A组均可见实在的骨生长;而B、C组因金属Cage的因素不易查见。结论腰椎单枚椎间Cage、两枚Cage及椎间1枚Cage加自体骨块融合配合椎弓根螺钉治疗腰椎滑脱症均能获得固定确实、复位理想及较为满意的临床疗效,而采用1枚Cage和1枚自体骨块同时椎间融合加椎弓根螺钉固定术其疗效更为理想、合理。
