Patterns of communications between musculocutaneous and median nerve: A cadaveric study

The brachial plexus is a complex communicating neural network formed in the axilla. The branching, union and reseparation of its nerve fibres frequently persists as communications between its branches, mostly the Musculocutaneous and the Median nerve. The knowledge of variable patterns of communications between Musculocutaneous nerve (MCN) and Median nerve (MN) explains the unexpected clinical signs and symptoms and also helps in having a better understanding of the field during surgeries in order to avoid neurological damage. In the present study, 38 cadavers (76 upper limbs) were dissected and the communications between MCN and MN were noted in 6.6% of the total cases (5 upper limbs). Some of these variations were rare.
