BAENA CALDAS, Gloria; PENA TOVAR, Elizabeth  e  ZUNIGA, Janneth. Supplantation of the superficial branch of the radial nerve by the lateral antebrachial cutaneous nerve. Medicas UIS [online]. 2013, vol.26, n.3, pp.51-55. ISSN 0121-0319.

Introduction: the sensitive innervation of the dorsum of the hand comes mainly from the superficial branch of the radial nerve, but this territory can be assumed by the lateral antebrachial cutaneous nerve. Objective: to describe a rare variation of the lateral cutaneous nerve of the forearm found in the cadaver lab of the Department of Morphology, at the Universidad del Valle in Cali, Colombia. Materials and Methods: male colombian cadaver, dissected by medical students. Results: the superficial branch of the radial nerve was absent and its sensory territory was totally assumed by the lateral antebrachial cutaneous nerve, which in the dorsum of the hand divided in the digital dorsal nerves for the thumb, index and middle fingers and the lateral half of the fourth digit. Discussion and Conclusion: considering the clinical and surgical implications that the distribution of a nerve can have, it is important to know precisely its normal anatomy and its possible variations, and direct them to the knowledge about the morphological characteristics of each population.
