摘要 目的比较颈椎后路侧块螺钉内固定椎板成形术治疗颈椎后纵韧带骨化症(ossification of cervical posterior longitudinal ligament,OPLL)中立位K线(-)而颈椎仰伸位K线(+)的患者(extension position,EP)和中立位K线(+)的患者(neutral position,NP)的临床疗效。方法回顾性分析2015—2018年北京医院收治颈椎后纵韧带骨化症患者40例,行颈椎椎板成形侧块螺钉内固定融合术,随访2年以上。根据K线状态分为颈椎中立位的K线(+)的OPLL患者(NP组)25例和颈椎中立位K线(-)仰伸位K线(+)的OPLL患者(EP组)15例。颈椎参数包括C2~7cobb角度和侧位片测量的屈伸运动范围(range of motion,ROM)。评估手术前后日本骨科学会评分(Japanese Orthopaedic Association,JOA),颈椎功能障碍指数(Neck Disability Index,NDI),视觉模拟评分(Visual Analogue Scale,VAS)。结果EP组NP组术前JOA评分差异有显著性(P<0.05)。两组术后C2~7cobb角度均提高,C2~7R O M均下降。NP组平均恢复率为65.18%±21.3%,优良率84.0%;EP组平均恢复率为49.18%±28.02%,优良率66.7%。EP组的JOA评分改善明显低于NP组,差异有显著性(t=2.042,P=0.048);两组的NDI评分均明显下降,两组VAS评分在最后一次随访时无明显变化。结论颈椎后路侧块螺钉固定椎板成形术对颈椎中立位的K线(-)而颈椎仰伸位的K线(+)的OPLL患者仍有良好的治疗效果。
