Pathogenesis and Treatment for a Throwing Shoulder

Abstract

We studied pathogenesis for a throwing shoulder evaluating the findings of arthrogram, MR-arthrogram and arthoscopy and studied the validity of the treatment evaluating the Shoulder Sports Score and Recovery rate. Twenty-four baseball players were studied. Insufficiency of SGHL with SLAP lesion induces anterior instability of the shoulder during throwing. We chose procedure SLAP repair for SLAP lesion, and debridement for a partial thickness joint side tear of rotator cuff. SLAP repair and debridement of rotator cuffs were done for on fourteen players. Debridement were done on six players Eighteen players could play baseball completely and recovered to the level before injury and six players could not. Players could recover completely got 96(85-100) points of the Shoulder Sports Score and players who could not recover got 61(35-95) points. Twelve players who had SLAP repair and debridement of rotator cuffs could recover. Only Two players who had debridement of the rotator cuffs could recover by insufficiency of SGHL. Twelve players can continue to play baseball for three years after their operations.
