Carpal tunnel compression and its surgical release has been well described. Motor branch anomalies of the median nerve have also been documented in the literature. Independent recurrent motor branch compression of the median nerve appears to exist in the presence of carpal tunnel symptomatology or as an independent entity. Eight presentations of concomitant or independent compression of the recurrent motor branch of the median nerve have been reviewed. These cases can be subdivided into cases presenting with or without carpal tunnel symptomatology, as well as into two types of independent compression patterns: the first being a direct fascial penetration and entrapment and the second being an acute angulation of the recurrent branch with apparent impingement by the transverse carpal retinaculum. Attention should be directed to the inspection and decompression of the motor branch of the median nerve in those cases that present thenar muscle pathology either clinically or electrodiagnostically.
腕管压迫及其手术松解已有详尽描述。文献中也记载了正中神经运动支的变异情况。正中神经独立的返支压迫似乎在存在腕管综合征症状时出现，或者作为一个独立的实体存在。本文回顾了正中神经返支合并或独立压迫的八种表现形式。这些病例可细分为有或无腕管综合征症状的病例，以及两种独立的压迫模式：第一种是直接的筋膜穿透和卡压，第二种是返支急性成角并明显受到腕横韧带的撞击。对于那些临床上或电诊断显示有鱼际肌病变的病例，应注意检查和松解正中神经的运动支。
