Sonographische Diagnostik bei Verletzungen des Schultereckgelenkes

The value of sonography for diagnosis of injuries of the acromioclavicular joint was examined in a prospective investigation. In 22 successive patients sonography was used in two defined positions, the results were compared with standard X-rays under weight loading. Only in 9 cases the findings could be controlled during operative exploration. In 16 cases, sonographic and radiologic findings were corresponding, in 6 cases both methods lead to different results. In all corresponding cases sonography was able to demonstrate direct or indirect signs of the damage of acromioclavicular and coracoclavicular ligaments. In the operatively controlled group in all cases the sonographic diagnosis was confirmed.
