title: The dual tendon palmaris longus variant causing dynamic median nerve compression in the forearm.
abstract: 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.
