Variant branches of brachial plexus - a case report

Author(s): Prashant Nashiket Chaware*, Jaideo Manohar Ughade, Sudhir Vishnupant Pandit and Gajanan Laxmanrao Maske

During routine dissection of brachial plexus we observed two upper subscapular nerves. These two upper subscapular nerves, lower subscapular nerve and axillary nerve arose from posterior division of upper trunk. Posterior cord gave thoracodorsal nerve and continued as radial nerve. We also found that anterior division of middle trunk divided into two branches; anterior division-a and anterior division-b. Anterior division-a joined anterior division of upper trunk to form the lateral cord. Anterior division-b joined medial root-1 of median nerve to form medial root-2 of median nerve. This medial root-2 joined with lateral root of median nerve to form median nerve. The anterior division-b carrying fibers from C7 primary ramus, contributed fibers to form medial root-2 of median nerve and then joined with the ulnar nerve. Presence of C7 root in ulnar nerve was clearly seen in our case, which is seldom visualized in routine dissection.
