We examined the factors related to shoulder pain of baseball players. We examined 569 pitchers who were qualified to participate in the national inter high school baseball tournament in Japan before games and reviewed them retrospectively. The items examined were experience of shoulder pain continued more than a month in throwing, range of motion (ROM), abduction power, acromion shape, great tuberosity (GT) shape, inferior and posterior shift by stress X-ray, and Bennetts lesion. The items related to the shoulder pain history were analyzed statistically. A hundred forty-seven pitchers of 569 (26%), who experienced shoulder pain continued more than a month, were classified into the pain group and the others were classified into the no pain group. The items related to the shoulder pain history were the GT shape and inferior shift. Players who experienced shoulder pain tended to have angle shaped GTs, and players who did not experience shoulder pain tended to have a positive inferior shift. ROM, abduction power, acromion shape, posterior shift, and Bennett lesion were not related to shoulder pain history. Players who have an angle shaped GT experienced shoulder pain more frequently, and players who have an inferior shift experienced pain less frequently.
