Reversed palmaris longus muscle: a report of two cases

Mark Twoon et al. Case Reports Plast Surg Hand Surg. .

Abstract

The palmaris longus muscle is the most superficial muscle of the volar forearm which demonstrates significant anatomical variance. A reversed palmaris longus muscle is one such variant. Here we discuss two cases in which reversed palmaris longus was postulated as a cause of wrist discomfort.

Keywords: Reversed palmaris longus; nerve compression; wrist pain.
