A Comparison between MRI Findings and Post Operative Reports of Labral Tears in the Shoulder

Parker-Reed, SSWAC

This experiment investigates the effectiveness of MR arthrography in 28 patients seen at Maine General Orthopedics over the last three years. All 28 patients had an arthroscopic surgery on the shoulders labrum by Dr. Anthony Mancini. I hypothesize the MR arthrography is accurate in diagnosing tears, but not accurate in describing the size and location of the tears. The results found portray the accuracy between MR arthrography findings and the post-operative reports. The study focuses not only on the ability of the MR arthrography to detect a labral tear, but also its effectiveness of finding the location (superior, posterior, inferior, or anterior) and size (Type I, II, III, IV). Using the details of reports, the MR arthrographys ability to describe and diagnose labral tears was found to be exact only 54% of the time, which supported my hypothesis.
