The flexor carpi ulnaris is a useful local muscle flap in the forearm and elbow. It is, however, an important palmar flexor and ulnar deviator of the wrist, and functional loss may arise from the use of this muscle in its entirety. The flexor carpi ulnaris is made up of two distinct neuromuscular compartments. This arrangement allows for splitting of the muscle and the potential use of the larger ulnar compartment as a local muscle flap while maintaining the humeral compartment as an ulnar deviator and palmar flexor of the wrist. We report two cases illustrating the clinical use of the split flexor carpi ulnaris as a local muscle flap.
尺侧腕屈肌是前臂和肘部一块有用的局部肌瓣。然而，它是腕关节重要的掌屈肌和尺侧偏肌，完全使用这块肌肉可能会导致功能丧失。尺侧腕屈肌由两个不同的神经肌肉部分组成。这种结构允许将该肌肉劈开，并且有可能将较大的尺侧部分用作局部肌瓣，同时保留肱骨部分作为腕关节的尺侧偏肌和掌屈肌。我们报告两例说明劈开的尺侧腕屈肌作为局部肌瓣的临床应用。
