A 57-year-old man presented with pain and paresthesia in both hands and was diagnosed with pronator teres syndrome. Surgical decompression of the left elbow and forearm revealed the median nerve in an unusual anatomic location, specifically running within the pronator teres muscle.
Anatomic anomalies of the pronator teres muscle and the path of the median nerve have been described. However, there are no reports of the median nerve entering and traveling within the pronator teres. Surgeons should be aware of this anomaly to avoid potential iatrogenic injury when performing an anterior surgical approach to the elbow and proximal forearm.
一名57岁男性因双手疼痛和感觉异常就诊，被诊断为旋前圆肌综合征。对左肘和前臂进行手术减压时发现正中神经处于异常解剖位置，具体是走行于旋前圆肌内。
已有关于旋前圆肌和正中神经走行的解剖变异的描述。然而，尚无正中神经进入并走行于旋前圆肌内的报道。外科医生在对肘部和前臂近端进行前路手术时应意识到这种变异，以避免潜在的医源性损伤。
