[Possibilities for using sonography in sports injuries of the shoulder joint].

Sonography is a useful tool for the examination of the shoulder joint. Concomitant cartilaginous and soft tissue lesions (Hill-Sachs, effusion, cuff-tears) can be visualized. Subacromial pathology can be differentiated. The type of instability in the unstable shoulder can be documented. The ultrasound investigation is of diagnostic value for the unstable shoulder as well as for the impingement shoulder in athletes. Therefore it may be helpful for planning the adequate treatment and also for the follow up of the patients.
