Thirty-five patients who had throwing injuries to the shoulder underwent arthroscopy of the shoulder in order to investigate the internal derangement. The average age was 21.6 years and the average duration of symptoms prior to arthroscopy was 14.0 months.<BR>The throwing sports involved were baseball (23), volleyball (8), tennis (2) and others (2) . All patients complained of pain in the shoulder during overhead activity and had not responded to conservative therapy.<BR>At arthroscopy, superior labrum separation was found in 16, anterior labrum tear or disruption in 9, posterior labrum flap tear in 1, and isolated rim rent of the supraspinatus in 5.<BR>Thus, 31 of the 35 (89%) demonstrated internal derangement of the shoulder, especially at the superior or anterior labrum portion, which is similar to the impingement syndrome or anterior subluxation clinically, and makes it difficult to demonstrate characteristic objective findings for such a throwing shoulder.<BR>We believe that it is necessary to perform a thorough arthroscopic examination for throwing injuries to the shoulder in order to establish an accurate diagnosis and appropriate management of the injury.
