Abstract

目的 探讨臂丛神经损伤肩胛上神经严重撕脱常规锁骨上前入路术式难以修复肩胛上神经时,后入路副神经移位修复肩胛上神经的疗效.方法 2003年2~10月对6例臂丛严重撕脱患者应用后入路副神经移位术式修复肩胛上神经,并观察肩胛冈上缘水平副神经与肩胛上神经的关系、术后斜方肌各部分肌力的变化及肩关节功能的恢复情况.结果 6例患者均顺利完成后入路副神经移位修复肩胛上神经.在肩胛冈上缘水平,副神经走行于斜方肌深面、筋膜下,定位于肩胛冈与肩胛骨内侧缘相交附近,肩胛上神经位于肩胛横韧带深侧肩胛切迹内,二者位置相对固定,相距3.5~5.5 cm,在肩胛冈上缘横切口内二者在无张力情况下直接拉拢端端吻接;术后随访18~26个月对斜方肌上部功能无明显影响,肩外展恢复35°~55°.结论 当臂丛损伤肩胛上神经撕脱严重常规手术难以解剖、进行修复时,后入路副神经移位术式是一种很好的选择。
