摘要 目的对比研究经椎旁间隙入路与正中入路单纯椎弓根钉内固定术治疗单节段Ⅰ、Ⅱ度峡部裂型腰椎滑脱症,探讨椎旁间隙入路在轻度峡部裂型腰椎滑脱的价值。方法 40例Ⅰ、Ⅱ度峡部裂型腰椎滑脱症患者,随机分为椎旁间隙入路组(椎旁组,n=20)和正中入路组(正中组,n=20),均采用单纯椎弓根钉内固定联合髂骨取骨植骨融合术,评估围手术期参数,融合率及疼痛状况。结果 (1)椎旁组较正中组手术时间短(P<0.01),切口长度短(P<0.01),术中出血量少(P<0.01),术后引流量少(P<0.01)。(2)VAS评分:所有患者术后疼痛都得到明显的缓解(P<0.01);两组组间比较,术后第1天及1、3、6个月,椎旁组疼痛改善程度较正中组明显(P<0.01)。(3)ODI:所有患者术后ODI值都改善明显(P<0.01);两组组间比较,术后第1、3个月,椎旁组ODI评分较正中组改善明显(P<0.01)。(4)术后1年,正中组融合率为90%,椎旁组融合率为95%,差异无统计学意义(P>0.05)。结论在治疗单节段Ⅰ、Ⅱ度峡部裂型腰椎滑脱症上,单纯椎弓根钉内固定联合髂骨取骨植骨融合术效果良好,椎旁间隙入路无论在围手术期的效果还是术后临床疗效上都较正中入路佳,具有临床推广价值。
