Clinical and Functional Significance of Accessory Brachialis Muscle: An Unique Anatomical Variant

A thorough knowledge of the variations in the patterns of muscle insertion and the consequent neurovascular entrapment due to them is important for orthopedic and plastic surgeons. During routine dissection, we encountered a unique occurrence of an accessory brachialis muscle (acBr) blending with th...
