The medial brachial cutaneous nerve (lesser internal cutaneous nerve; medial cutaneous nerve of arm) is distributed to the skin on the medial brachial side of the arm.

Anatomy

It is the smallest branch of the brachial plexus, and arising from the medial cord receives its fibers from the eighth cervical and first thoracic nerves. It passes through the axilla, at first lying behind, and then medial to the axillary vein, and communicates with the intercostobrachial nerve.

It descends along the medial side of the brachial artery to the middle of the arm, where it pierces the deep fascia, and is distributed to the skin of the back of the lower third of the arm, extending as far as the elbow, where some filaments are lost in the skin in front of the medial epicondyle, and others over the olecranon.

It communicates with the ulnar branch of the medial antebrachial cutaneous nerve.

Eponym

The term "nerve of Wrisberg" (after Heinrich August Wrisberg) has been used to describe this nerve.^[1]^[2]

However, the term "nerve of Wrisberg" can also refer to the nervus intermedius branch of the facial nerve.^[3]^[4]^[5]

Brachial plexus compression (BPC) occurs above the clavicle as neurogenic thoracic outlet syndrome (NTOS) and below as neurogenic pectoralis minor syndrome (NPMS). It was recently noted that 75% of the adults seen for NTOS also had NPMS and in some this was the only diagnosis. This is also true in c

BACKGROUND: Contralateral C7 nerve transfer to the median nerve has been used in an attempt to restore finger flexion in patients with total brachial plexus avulsion injury. However, the results have not been satisfactory mainly because of the requirement to use a long bridging nerve graft, which ca
