RESUMO
The Palmaris longus (PL) is a fusiform muscle that is part of the superficial flexors on the anterior compartment of the forearm. It originates from the common flexor tendon at the medial epicondyle of the humerus and inserts at the flexor retinaculum. The Palmaris longus has been reported to present in multiple variations. Some of these variations include agenesis, reversal, and multiple bellies of the muscle. The Palmaris longus is clinically significant as a landmark for carpal tunnel syndrome steroid injection, hand anesthesia, and used as a surgical graft. Medical students at the University of Medicine and Health Sciences, St. Kitts and Nevis, encountered a unique variation of the PL during cadaver dissection. This article explores the exclusiveness of a three-tendinous head reverse PL and what makes it unique compared to similar findings in other reports.
