Radial duct syndrome

As early as 1883, some people thought that the entrapment of the radial nerve or radial nerve branch may be one of the causes of tennis elbow. In 1905, Guillain reported a case in which a wind musician caused occlusion of the posterior interosseous nerve due to repeated supination and pronation of the forearm. In the future, cases of posterior interosseous nerve entrapment have been reported clinically. Aneurysms, tumors, and fractures of the elbow are considered to be the cause of the posterior interosseous nerve entrapment. However, for many years, tennis elbow has been the main diagnosis of pain in the proximal outer forearm. In 1956, Michele and Krueger described the clinical signs and symptoms of radial pronator syndrome. In 1960, they further reported the clinical efficacy of proximal pronation muscle release in the treatment of refractory tennis elbow. In 1972, Roles and Maudsley proposed the concept of radial tunnel syndrome, and analyzed the anatomical area, structural features, nerves that may be stuck, and the causes of tennis elbow. In 1979, Werner and Lister first confirmed the relationship between radial canal entrapment and pain in the lateral elbow and the proximal forearm through detailed data for the first time, and put forward the points of identification with external epicondylitis of the humerus and the connection with the tennis elbow. In recent years, with the continuous deepening of research on radial duct syndrome, the understanding has been perfected.
