Documented anatomical variations are important not only for the study of the subject of anatomy, but also in clinical situation. This knowledge would aid surgeons in planning a preoperative strategy for surgical procedures and reconstructive surgery. The right forearm of a 35-year-old embalmed male cadaver present a splitting of the median nerve in the proximal 1/3 of the forearm to form medial and lateral divisions that accommodate an anomalous muscle. The split median nerve reunites at the distal 1/3 and continues as a single nerve. The anomalous muscle arises by muscle fibers from flexor digitorum superficialis and inserted by tendon into flexor digitorum profundus. There was no such variation in the left forearm. The knowledge of such anatomical variations is important to clinicians and surgeons in interpreting atypical clinical presentations and avoiding unusual injury during surgery.
有记录的解剖变异不仅对于解剖学学科的研究很重要，在临床情况下也很重要。这些知识将有助于外科医生为外科手术和重建手术制定术前策略。一具35岁经防腐处理的男性尸体的右前臂，正中神经在前臂近端1/3处分裂形成内侧和外侧分支，中间容纳一块异常肌肉。分裂的正中神经在远端1/3处重新合并并继续作为单一神经。这块异常肌肉由来自指浅屈肌的肌纤维起始，通过肌腱插入指深屈肌。左前臂没有这种变异。了解这种解剖变异对于临床医生和外科医生解释非典型临床表现以及避免手术中出现异常损伤很重要。
