Abstract

Introduction: The radial nerve anterior to the lateral epicondyle divides into superficial and deep terminal branches. Entrapment or compression neuropathy of the deep branch of radial nerve (DBRN) or posterior interosseous nerve (PIN) leads to radial tunnel syndrome or PIN syndrome. It may also be one of the differential diagnoses of lateral epicondylitis. This study was performed on 38 upper limbs of 19 formalin-fixed cadavers. In most of the instances it was found that the radial nerve divided 1.4 cm above the interepicondylar line (IEL). The nerve to extensor carpi radialis brevis (ECRB) arose at 1.2 cm from the IEL. We also observed the nature of some of the important structures which may compress deep branch of radial nerve. This knowledge is important for exploring elbow region during surgical decompression of DBRN.
