A wide variety of anatomic variations of the median nerve at wrist have been reported and the awareness of these variations are essential for the surgeon treating carpal tunnel pathologies to avoid inadvertent injury to the nerve during surgery. We report a rare case of bifid median nerve accompanied by a persistent median artery found incidentally in a patient who underwent flexor tendon reconstruction for subcutaneous tendon rupture. The current literature regarding the anomaly is reviewed and surgically relevant aspects are discussed.
腕部正中神经存在多种解剖变异，已有相关报道。对于治疗腕管疾病的外科医生而言，了解这些变异至关重要，可避免手术过程中意外损伤神经。我们报告了1例罕见的双叉正中神经病例，该病例伴有持续正中动脉，此情况在1例因皮下肌腱断裂而接受屈肌腱重建的患者中偶然发现。本文回顾了有关该异常情况的现有文献，并讨论了与手术相关的方面。
