Abstract

Introduction: The brachial plexus is the largest and most complex neural plexus in the body located in the neck and axilla. So far, there have been many reports of various variations in the brachial plexus that are of clinical significance. In the present study, while dissecting the upper limb of a 54-year-old man in the dissection room of Shahid Sadoughi University of Medical Sciences in Yazd, a rare variation was observed in the lateral cord branches of the plexus. In this case, the medial pectoral nerve, which normally separates from the medial cord, originated from the lateral cord. Awareness of this variation is important for anatomists, surgeons, anesthesiologists and radiologists to interpret the graphs, etc., and can help to reduce clinical complications during surgery and better interpret and diagnose the graphs.

Abstract

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.
