TEAR OF THE POSTERIOR SHOULDER STABILIZERS AFTER POSTERIOR DISLOCATION - MR-IMAGING AND MR ARTHROGRAPHIC FINDINGS WITH ARTHROSCOPIC CORRELATION

OBJECTIVE, The purpose of this article is to describe the findings on MR imaging and MR arthrography in posterior capsular tear and teres mi nor muscle injury after posterior dislocation. We also correlate MR im aging with the arthroscopic findings and present treatment options for these patients. CONCLUSION. MR imaging is helpful in diagnosing abnor malities caused by posterior dislocation injuries and in directing the rapy. Teres minor muscle and capsular injuries may occur without the t ypical reverse Bankart lesion. Isolated teres minor muscle tears seen on MR imaging after posterior dislocation injury may cause pain. Howev er, no consensus exists as to whether the lesions seen on MR images in these patients should be treated surgically or conservatively.
