![]() Physical examination is not sufficient to diagnose entrapment syndromes ( 3). Radial nerve entrapment symptomatology can be misperceived as musculoskeletal pathologies, which contributes to underdiagnosis of radial nerve injury and delayed treatment ( 1). Symptoms may not manifest at the time of the initial insult or injury. Subsequent injury can be categorized based on increasing severity (i.e., neuropraxia, axonotmesis, and neurotmesis) ( 2). ![]() The extent of nerve injury depends on the intensity of the mechanical and the temporal compression. Compressive neuropathies are more prevalent and can occur under a variety of circumstances, most commonly from repetitive activities, either recreational or occupational ( 1). Entrapment, or compression of radial nerve neuropathy, can be categorized as compressive and non-compressive. This anatomy provides an opportunity for radial nerve entrapment resulting in peripheral neuropathy of the arm, forearm, and hand. The radial nerve is the largest branch of the brachial plexus, which traverses posteriorly around the humerus, bifurcating at the radiocapitellar joint, forming the superficial and deep branches.
