This article describes a variant of palmaris longus muscle resulting in median nerve compression in the mid forearm. Although the palmaris longus has several well-documented anomalies, these seldom lead to nerve compression. The dual tendon, central muscle belly variant observed in this case is the first of its kind to be reported causing compressive neuropathy at this level. This is of both anatomical and clinical interest as it reminds surgeons of the anatomical variations of this unique muscle and presents a new mechanism of nerve compression in the forearm.
本文描述了一种导致前臂中段正中神经受压的变异型掌长肌。尽管掌长肌有几种已有文献记载的异常，但很少导致神经受压。在这种情况下观察到的双肌腱、中央肌腹变异是首例报告的在该水平引起压迫性神经病的病例。这具有解剖学和临床意义，因为它提醒外科医生注意这种独特肌肉的解剖变异，并提出了前臂神经压迫的新机制。
