A FLESHY PALMARIS LONGUS MUSCLE

Abstract

The most commonly reported variations of the Palmaris longus muscle are in its presence and the number of bellies. We however report a new variation, in which the muscle was entirely fleshy, instead of the predominantly tendinous muscle. This rare variant can pose a challenge to a surgeon in the exploration of the carpal tunnel, and compress the distal part of the median nerve. Clinicians should be wary of an entirely fleshy palmaris longus muscle.
