This article describes the concomitant presence of two anomalous forearm muscles in a 20-year-old man, discovered accidentally during an operation for a forearm injury. The first one was similar to a reverse palmaris longus muscle except for its direction to the Guyon's canal. The second one originated from the radial antebrachial fascia, superficial to all other forearm muscles in the lower half of the forearm, then diverged medially and extended into the Guyon's canal and was innervated by the ulnar nerve. The patient had no symptoms related to overcrowding of the Guyon's canal before the injury. A hand surgeon should be well informed about the anatomic variations of the hand to be comfortable during surgical practice.
本文描述了一名20岁男性前臂意外出现两块异常肌肉的情况，这是在一次前臂损伤手术中偶然发现的。第一块肌肉类似于反向掌长肌，只是其走向Guyon管。第二块肌肉起自前臂桡侧筋膜，在前臂下半部位于所有其他前臂肌肉的浅层，然后向内分支并延伸至Guyon管，由尺神经支配。该患者在受伤前没有与Guyon管拥挤相关的症状。手外科医生应充分了解手部的解剖变异情况，以便在手术操作中得心应手。
