Abstract

Introduction:The median nerve is formed by the union of a lateral and a medial root from the lateral and medial cords of brachial plexus. Reports on the existence of variations in the formation, branching and communication of median nerve are seen in the literature. However, there are very few reports on the involvement of two additional lateral roots in the formation of the median nerve. Such variations are of considerable importance for surgeons, physiotherapists and other clinicians. The details regarding the formation of the median nerve, developmental considerations and its importance have been discussed here. Case report:Apart from the normal roots, two additional lateral roots were given off from the lateral cord at the level of the second part of the axillary artery. These roots then coursed superficial to the axillary artery from the lateral to medial side to join the medial root, on the medial side of the axillary artery. The medial root then crossed on to the lateral side of the axillary artery to join the lateral root to form the median nerve. The rest of the course of the median nerve was found to be normal. Conclusion: Surgeons during surgeries of the axilla and physiotherapists during rehabilitation would require knowledge of such variations in the axilla, along with use for other clinicians too.
