Abstract

During routine dissection classes to under graduate medical students, we observed an anomalous flexor carpi ulnaris muscle associated with abnormal ulnar nerve and ulnar artery in the distal part of forearm. There was an additional belly arising from the lower part of the flexor carpi ulnaris muscle and crossed ulnar nerve and vessels, median nerve and ended in a broad aponeurosis which crossed the tendons of flexor digitorum superficialis and merged with the deep fascia and flexor retinaculum. The ulnar nerve and ulnar artery divided into their terminal branches in the lower part of the forearm. However, the distribution of the terminal branches of both ulnar nerve and artery were normal. An understanding of these unusual findings may be clinically relevant in describing the anterior compartment of the forearm.
