Isolated compression of the recurrent motor branch of the median nerve is an uncommon condition encontered in the daily life of the hand surgeon. Its early identification and correction can optimize functional outcomes. Among the few causes described, there are only 2 case reports of compression by fascial bands. We present a case of isolated compression of the recurrent motor branch of the median nerve secondary to anomalous fascial bands in a 34-year-old male patient, with significant atrophy of the thenar musculature of the right hand. Electroneuromyography showed isolated involvement of abductor pollicis brevis, with no sensory changes. The patient underwent exploration and decompression, recovering opposition and thumb function in 6 months.
正中神经返支单独受压在手部外科医生的日常工作中并不常见。早期识别和纠正正中神经返支单独受压可优化功能预后。在少数已描述的病因中，仅有 2 例由筋膜带引起的受压病例报告。我们报告了 1 例 34 岁男性患者因异常筋膜带引起的正中神经返支单独受压的病例，右手大鱼际肌明显萎缩。肌电图显示拇短展肌单独受累，无感觉改变。患者接受了探查和减压手术，6 个月后恢复了对掌和拇指功能。
