Abstract

This case report presents a 72-year-old female with a unique anatomical variation of the median nerve recurrent motor branch that has not been described in the literature. During her open carpal tunnel release, the recurrent motor branch was found to divide from the median nerve within the carpal tunnel, pierce the proximal aspect of the transverse carpal ligament in a transligamentous fashion, and then immediately divide into one branch that pierced the thenar muscles and another branch that traveled superficial to the transverse carpal ligament before piercing the thenar muscles more distal. This variation in anatomy stresses the importance of thoughtful incision design and direct visualization of all structures during carpal tunnel release.

摘要

本病例报告介绍了一名72岁女性，其正中神经返支存在独特的解剖变异，此前文献中未见描述。在她的开放性腕管松解术中，发现返支在腕管内从中正中神经分出，以经韧带的方式穿过腕横韧带近端，然后立即分为一支穿入鱼际肌，另一支在腕横韧带浅面走行，更远端时穿入鱼际肌。这种解剖变异强调了在腕管松解术中精心设计切口并直接观察所有结构的重要性。
