Aims and objectives: The radial tunnel syndrome (RTS) is a compressive entrapment of the posterior interosseous nerve (PIN) at the elbow(1–5), which is characterized by pain along the lateral aspect of the proximal forearm, without motor deficits(1,2), especially with repeated elbow extension and forearm rotation(6,7). [...]

Methods and materials: The radial nerve carries the fibers derived from the nerve roots C5-T1. In the arm, the nerve runs between the brachialis and biceps brachii tendon medially and the brachioradialis, extensor carpi radialis brevis and longus muscles laterally. The radial nerve bifurcates within 3 cm above and 3 cm be[...]

Results: 540 patients were eligible for the study (n= 380 women, 160 men, most in the 3th through 5th decades of life), but only 57% (n= 309/540) had clinical diagnosis or suspicion of lateral epicondylitis / tendinitis and 5.4% (10/540) of RTS (Table 1). US diagnosis of lateral epicondylitis was suggested[...]

Conclusion: The RTS was first described in 1956 by Michele Krueger who called it as “radial pronator syndrome”. In 1972 Roles and Maudsley suggested this syndrome as an explanation for resistant or chronic tennis elbow and it has been further elaborated in 1959 by Kaplan and in 1979 by Lister et al who describe[...]
