Exploring anomalous muscular architecture: a case of the dorsoepitrochlearis muscle

Abstract

Anatomic variations in the upper limb are of great significance as they pose implications on surgical techniques and raise the risk of  intraoperative injury.The presence of dorsoepitrochlearis muscle was discovered during routine dissection of a male cadaver at the  Department of Human Anatomy. This variant muscle was found in the right axillary region, originating as a single strip from latissimus  dorsi and attaching onto the medial epicondyle of the humerus. Dorsoepitrochlearis is a rare anatomical variation whose spectrum of  clinical manifestation may extend from asymptomatic to muscular paresthesia and atrophy as well as motion restriction. A rich basis of  knowledge of anatomical variations is crucial in diagnosis and management.
