OBrien noted in a series of patients it was also excellent for detecting labral pathology. The patients will be placed at 90 of flexion 10 of adduction and full internal rotation with the forearm pronated.

Our results refuting the proposed anatomic basis of the OBrien test may partly explain the varying results of subsequent diagnostic studies that replicated the original test. Many normally stable shoulders such as those of gymnasts will demonstrate substantial translation on these laxity tests even though they are asymptomatic.

The OBrien and crank tests were not sensitive clinical indicators for detecting glenoid labral tears and other tears of the anterior and posterior labrum. To detect superior glenoid labral lesions andor type 2 superior labrum anterior and posterior SLAP lesions which is fraying of the superior glenoid labrum along with detachment of the biceps anchor on the shoulder.
