In supinator syndrome there is compression damage to one of the branches of the radial nerve in the elbow area. Patients suffer from pain in the posterior side of the forearm, which intensifies if pressure is applied to the outside of the elbow. In advanced stages, the muscles are impaired in function. Supinator syndrome also causes deficiencies in hand and finger extension, so that a fully pronounced clinical picture of supinator syndrome is that characterized by so-called “wrist drop”. Pain intensifies when the wrist is extended against resistance (Thomas-Test). Supinator syndrome often occurs at the same time as tennis elbow.
