Radial nerve formation in the axillar region
Radial nerve formation in the axillar region

Summary/Abstract: Introduction: The radial nerve is the terminal and largest branch of the posterior cord of the brachial plexus. It supplies the majority of the posterior and extensor components of the arm and forearm. There is little information about its possible variable formation in the axilla in the available literature. Research objectives: The aim of our work was to elucidate the variability of radial nerve formation in the axillar region. Material and methods: Our work was realised on 50 human bodies, whereas the brachial plexus was revealed on both sides (we analysed totally 100 of brachial plexuses). Results: We have observed the communication of the radial nerve with the ulnar nerve in 2 cases (2 %) - 1 case on the right side, 1 case on the left side. We did not follow the further distal courses of the brachial plexus terminal branches. We confront our findings with similar works from the literature and give a possible embryological basis for the explanation of the variation presence. Conclusion: Reports of the peripheral nerve’s anatomical variations are important to medical personnel: especially to orthopaedists, traumatologists, neurophysicians, physiotherapists, radiologists, anaesthesiologists, anatomists or also to other medical specialists.
