We evaluated the diagnostic value of the stress view in the shoulder joints. We performed the stress view in shoulder joints using a Telos shoulder positioning device from 2000 to 2002. There were eighteen patients and thirty-six shoulders. The positioning of the anterior stress view was abduction at 90 degrees and external rotation at 60 degrees, and the posterior one was abduction at 90 degrees and neutral rotation. A fifteen kg stress was obtained in both anterior and posterior views. The position of the center of the humeral head was evaluated in the glenoid from the it's anterior edge. We divided it into three groups: group A (recurrent anterior shoulder dislocation) six cases, group B (multidirectional instability of the shoulder) four cases and group C (throwing shoulder) eight cases. The mean of anterior stress in group A was 33.3% on the operated side and 50.8% on the other side. It was a significant difference. The posterior ones in each were 54.2% and 56.9%. The mean of anterior stress in group B was 34.7% on the operated side and 43.1% on the other. The posterior ones in each were 71.1%and 70.6%. In group C they were 47.6% on the injured side and 53.3% on the other. The posterior ones in each were 50.9% and 58.8%. There was a significant difference. This stress view in shoulder joints had a diagnostic value.
