Anterior interosseous nerve palsy is rare. Isolated neuropraxia of its branch to the flexor pollicis longus is even rarer. We present a case of a 24-year-old man who presented with weakness of his left thumb flexion after sustaining closed fracture of the proximal third of his left radius. On exploration, the anterior interosseous nerve and its branches was found to be intact as was the flexor pollicis longus. Electrophysiological studies demonstrated acute left anterior interosseous nerve neuropathy. Electromyography showed discrete motor unit at the flexor pollicis longus. Two months later the patient had full recovery of the flexor pollicis longus. We would like to highlight this rare occurrence and present a detailed history of this case to increase awareness amongst clinicians regarding this condition.
骨间前神经麻痹较为罕见。其支配拇长屈肌的分支发生孤立性神经失用症则更为罕见。我们报告一例24岁男性病例，该患者在左侧桡骨近端三分之一处发生闭合性骨折后出现左拇指屈曲无力。探查发现，骨间前神经及其分支以及拇长屈肌均完好无损。电生理研究显示为急性左侧骨间前神经病变。肌电图显示拇长屈肌处有离散的运动单位。两个月后，患者拇长屈肌完全恢复。我们希望强调这一罕见病例，并详细介绍该病例的病史，以提高临床医生对这种疾病的认识。
