A Case Report of a Rare Variation of the Medial Cutaneous Nerve of Forearm

Abstract: (570 Views)

Introduction: The brachial plexus is the largest and most complex nerve network in the body, which is formed in the neck and enters the axillary cavity after passing under the clavicle. So far, many variations have been reported in the brachial network, which are clinically important. The plexus has three cords, one of which is the medial cord. The medial cutaneous nerve of the arm and the medial cutaneous nerve of the forearm are the branches of the medial cord that innervate the skin of the medial surface of the arm and forearm, respectively. In this study, a rare variation was observed in the branches of the medial cord of the brachial plexus during the dissection of the upper limb of an approximately 80-year-old man in the Dissection Hall of Shahid Sadoughi University of Medical Sciences, Yazd, Iran. Thus, in normal condition, there is no connection between the medial cutaneous nerve of the arm and the medial cutaneous nerve of the forearm, and each of them innervates the skin of the medial arm and forearm separately, but in this case, these two nerves are connected. And since knowing this type of variation is very important for surgeons, more studies are needed to determine its prevalence in the population.

Keywords: Brachial plexus, Medial cord, Medial cutaneous nerve of the forearm, Medial cutaneous nerve of the arm.
