Abstract:
The most common indications for surgical exposure of the radial nerve, along its course from axillary fossa to proximal part of forearm is repair of its open or closed traumatic injuries, surgical removal of nerve tumors and for treatment of entrapment neuropathies. Purpose of this work was to analyze topographical relations of radial nerve in the arm with reference to easily detectable anatomical landmarks. 114 upper limbs from 57 formalin-fixed cadavers were dissected meticulously to expose the radial nerve from its origin to its termination. The distance of origin of radial nerve and origin of branch to long head of triceps brachii and branch to medial head of triceps brachii originating in axilla is measured from tip of coracoid process of scapula. The distance of origin of branch to lateral head of triceps brachii and branch to medial head of triceps brachii originating in radial groove were measured from medial epicondyle of humerus. Distance of origin of branch to brachioradialis, branch to extensor carpi radialislongus and branch to anconeus were measured from the lateral epicondyle of humerus. Although efforts have been made by several authors to obtain precise anatomical data regarding the course of radial nerve and its topographical relations, measurements of radial nerve position with reference to reliable anatomical landmarks in the arm are seldom reported.This data will be useful for understanding the effect of entrapment or traumatic lesions along the course of radial nerve, for choosing the correct procedures and for allowing safe positioning of fixation implants.
Keywords: Radial nerve, triceps brachii, radial groove, medial epicondyle, topography, entrapment
