Abstract

Objective: The aim of this study was to analyze the incidence of nerve communication between the musculocutaneous and median nerve .

Methods: Anatomical dissection of 40 limbs from 20 fetal cadavers was performed at the Laboratory of Anatomy, Faculdade de Ciências Médicas e da Saúde da Pontifícia Universidade Católica de São Paulo .

Results: A communicating branch was found in 10 upper limbs. In nine limbs there was a musculocutaneous-median anastomosis (type I); and in one limb there was a median-musculocutaneous anastomosis (type II) .

Conclusion: It is very important to know these anatomical variations, especially when considering clinical examination, diagnostic, prognostic and surgical treatment. Level of Evidence IV, Case Series.

Keywords: Anastomosis, surgical/methods; Median nerve; Musculocutaneous nerve; Nerve transfer; Ulnar nerve.
