Abstract

The current report is unique as it highlights the coexistence of triple roots of median nerve, three heads of biceps brachii muscle and communicating branches from musculocutaneous nerve to median nerve in right brachium of an Indian male cadaver. The extra root of median nerve needs to be kept in mind while performing interventions in the shoulder region. The communication between musculocutaneous nerve to median nerve in arm may be beneficial in cases of median nerve injury in axilla. The supernumerary head of biceps brachii may be a potential cause of neurovascular compression and dislocation during humeral shaft fracture. The knowledge of such variations may be especially advantageous to radiologists, orthopaedic surgeons and neurosurgeons.
