title: Subacromial impingement syndrome secondary to scapulothoracic dyskinesia.
abstract: The authors describe two cases of subacromial impingement syndrome of the shoulder secondary to scapular dyskinesia caused by a tumor in young adults. The two tumors, an osteochondroma and a ganglion, were located in the scapulothoracic joint and inhibited normal kinesis of the scapula during arm motion.
