In 2004, we reported the location of a Bennett lesion coincides with the origin of the triceps long head. We therefore considered that the triceps is more associated with a Bennett lesion than is the posterior capsule. So we thought it was important to check the origin of the triceps long head.<BR>The purpose of this study was to clarify the efficacy of Triceps Long head test (TL test) for throwing injury. We devised a TL test that is a stress test of the triceps long head. In the maximum horizontal flex position, the patient extend only the elbow joint. We thought that when the patient felt pain at that time, there was some inflamation or damage in the proximal end of the triceps long head. The subjects were 28 patients who consulted our clinic from, 2007 to 2008, because of throwing disturbance and were positive in the TL test. We investigated the triceps long head by ultrasonography(US) and checked their shoulder. 26 cases out of 28 had some damage in the proximal end of the triceps long head by US. TL test changed to negative from 1 week to 4 months in 24 cases, 4 patients had a constant pain, and 3 cases had Bennett lesion. 27 cases had GIRD(glenohumaral internal rotaion deficit). All 28 cases had a tenderness at the origin of the triceps long head.<BR>We made sure of the relation between TL test and the some damage of the triceps long head. TL test is useful for the diagnosis of posterior pain in throwing injury.
