Carl J. Basamania M.D.- Discussion: - rotatory stress test was developed to reliably test for anterior instability of of the shoulder; - in most cases, the test will identify a Bankart Lesion, but on occassion the test will pick up a Hagl lesion (avulsion of IGHL); - Technique: - test begins on normal side; - w/ the arm supported in the surgeon's axilla, and one hand translates the shoulder anteriorly; - the shoulder is then abducted and externally rotated; - the shoulder is again translated anteriorly; - w/ a normal inferior glenohumeral ligament, anterior translation should decrease markedly;
