摘要
目的了解保留C2和C7棘突肌肉止点的改良颈椎后路椎管扩大成型术在对颈椎前凸角度的影响,轴性症状的发生率等方面的临床效果,探讨保留颈后部肌肉止点在防止颈椎后路椎管扩大成型术术后并发症方面的作用。方法回顾性分析2001年1月至2009年1月28例采用保留C2和C7棘突肌肉止点的改良颈椎后路椎管扩大成型术和21例传统的颈椎后路椎管扩大成型术在术后和术后3个月随访时JOA改善率,颈椎Cobb角和Ishihara指数的变化,轴性症状的情况,手术时间和出血量方面的结果,并对结果进行统计学分析。结果改良颈椎后路椎管扩大成型术和传统术式在术后JOA改善率方面的作用相同,Slac术式术后3个月随访时在颈椎Cobb角和Ishihara指数的变化上要小于传统术式,改良颈椎后路椎管扩大成型术在术后随访时患者出现轴性症状的比例和新出现症状的比例要低于传统术式,改良颈椎后路椎管扩大成型术的手术时间要少于传统术式。结论颈椎后路手术中尽量避免对肌肉的损伤可以减少术后并发症的发生率。改良颈椎后路椎管扩大成型术可以更好的保护颈后部的伸肌组群,可以获得与传统术式相同的神经减压效果,可以更好的维持颈椎前凸角度,术后轴性症状的发生率较低。
