Medial Antebrachial Cutaneous Nerve Harvest - Dr. Susan E. Mackinnon

Video Description

The medial antebrachial cutaneous (MABC) nerve is a viable donor for nerve grafts and our institution's preferred donor nerve graft for upper extremity nerve reconstructions. The MABC nerve is harvested from the medial aspect of the arm and is found branching distally into an anterior and posterior branch. The anterior and/or posterior branch can be harvested depending on the length and diameter required for nerve reconstruction. After harvesting the MABC nerve, the distal end of the MABC nerve is end-to-side transferred to an adjacent functional sensory nerve through an epineural window. in this case, the anterior branch of the MABC nerve is harvested for graft material and the anterior branch is end-to-side transferred to the posterior branch of the MABC nerve.
