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.
