The radial nerve route through elbow constitutes, for this nervous element, a way with risk of intrinsic or extrinsic injuries. Morphologic changes of the structures that constitute the denle of the radial nerve, pathological as much traumatic, can determine it atrapment and compression, determining the damage of the nerve and/or the inflammation located at level of the surrounding structures. 30 forearm-elbow, preserved with formol to 10%, were dissected, and the subsequent analysis of the disposition of the muscular structures and insertion of the same ones, will determine the possible points of anatomical risk that they will affect the radial nerve or its branches in the brachial track or in the proximal forearm (relation with the supinator muscle and extensor carpi radialis longus and brevis muscles).We defined 4 zones of atrapment and compression of the radial nerve and its branches: 1. External intermuscular setum; 2. Extensor carpi radialis brevis muscle; 3. Supinator muscle , atlevelof theFrohse's Arch;4. Supinator muscle, when coming out of the muscular mass, in the back of the forearm. The compression of the radial nerve at level of the elbow is one of the frequent neuropathies of the superior member. It is for that reason that the objective of this work consists of analyzing the anatomical aspects of the route of the radial nerve in its passage from the arm to the forearm, specially relations with morphological structures, whose alterations determines pathologies of the radial nerve which can take to pain, parestesies, with lost sensorial and functional impotence.
