Medial Antebrachial Cutaneous Nerve


- Anatomy:
    - innervation: (C8, T1);
    - medial antebrachial cutaneous nerve descends in the arm anterior and medial to brachial artery;
    - at distal to mid forearm level, nerve emerges from under brachial fascia adjacent to basilic vein;
    - it innervates the skin of anterior & medial surfaces of forearm as far as wrist;
    - nerve divides into 1-3 branches above the elbow as it travels to the medial epicondyle and olecranon;
          - these nerve branches may pass either proximal or distal to the epicondyle;

- Graft Harvest:
    - MABC nerve can be used for nerve "cable" grafts (see nerve repair menu)
    - the anterior branch of this nerve is harvested 2 fingerbreadths anterior and distal to the medial epicondyle

         



Use of the anterior branch of the medial antebrachial cutaneous nerve as a graft for the repair of defects of the digital nerve.
