A 63-year-old woman with a history of a malunited distal radius fracture presented with left hand pain and inability to flex her thumb, index, and middle fingers. Anterior interosseous neuropathy was suggested because of abnormal electromyography findings. However, magnetic resonance imaging later revealed flexor tendon ruptures. A distal radius corrective osteotomy with autograft and volar fixation was performed with tendon transfers and carpal tunnel release.
Attritional flexor tendon rupture after a nonoperatively managed distal radius fracture is rare but remains an important differential diagnosis in patients with signs and symptoms of anterior interosseous nerve paralysis.
一位 63 岁女性，既往有桡骨远端骨折畸形愈合病史，出现左手疼痛和无法弯曲拇指、食指和中指。由于肌电图检查结果异常，提示正中神经损伤。然而，磁共振成像后来显示屈肌腱断裂。进行桡骨远端矫正截骨术，自体骨移植，掌侧固定，并进行肌腱转位和腕管松解术。
非手术治疗的桡骨远端骨折后发生的磨损性屈肌腱断裂较为罕见，但在出现正中神经损伤症状和体征的患者中仍是重要的鉴别诊断。
