The purpose of this study was to determine the availability of a local anesthetic test for throwing athletes with posterior shoulder pain. Forty-eight cases with posterior shoulder pain in throwing athletes were evaluated. Their mean age was 26.6 years old, and the mean period from onset to the test was 34.4 months. After 1 % lidocaine was injected into the posterior margin of the glenoid rim, each patient did some pitching. We observed the ball speed and questionned each patient about pain relief. In local anesthetic tests : 5 cases were ineffective (all cases ; Bennett lesion -, tenderness of the RI +, slipping +). 19 cases were effective (Bennett lesion -7 cases, tenderness of the RI + 12 cases, slipping + 4 cases, PL lesion of the humeral head + 9 cases). 24 cases were very effective (Bennett lesion -9 cases, tenderness of the RI + 11 cases, slipping + 1 cases, PL lesion of the humeral head + 0). We considered that the posterior margin of the glenoid rim must be taken into consideration as a symptomatic lesion of posterior shoulder pain during the throwing motion. A local anesthetic test into the posterior margin of the glenoid rim was available for throwing athletes with posterior shoulder pain.
