Patients with arthrogryposis may exhibit inability to flex the elbow. A free functional gracilis muscle transfer (FFGMT) can be used to restore elbow flexion. In our search of the available literature, we have not seen any descriptions of using a motor branch to the pectoralis major as a donor nerve to establish elbow flexion. We performed an FFGMT for restoration of elbow flexion in an arthrogrypotic patient with no active elbow flexion, who had a Medical Research Council (MRC) muscle grade of 0. We report our 4.5-year outcomes. After undergoing an FFGMT for elbow flexion, our patient was able to gain an MRC grade 4 and achieve an arc of motion of 25° to 140°. An FFGMT for elbow flexion may be performed successfully using a motor branch to the pectoralis major.
患有先天性关节挛缩症的患者可能表现出无法弯曲肘部。游离功能性股薄肌转移术（FFGMT）可用于恢复肘部弯曲。在我们对现有文献的搜索中，尚未见到任何使用胸大肌运动支作为供体神经来建立肘部弯曲的描述。我们对一名没有主动肘部弯曲功能、肘部弯曲 MRC 分级为 0 级的先天性关节挛缩症患者进行了 FFGMT 以恢复肘部弯曲功能，我们报告了患者 4.5 年的随访结果。在接受 FFGMT 以恢复肘部弯曲功能后，患者的肘部弯曲 MRC 分级达到了 4 级，活动度从 25°增加到 140°。使用胸大肌运动支进行 FFGMT 以恢复肘部弯曲功能可能是成功的。
