ABSTRACT

Introduction: Subscapularis tendon injuries as part of rotator cuff pathology are difficult to diagnose, the presence of indirect signs such as subluxation of the long head of the biceps are used as diagnostic markers of subscapularis rupture. Material and methods: A consecutive series of cases that required arthroscopy surgery were analyzed to identify the diagnostic utility of long head biceps subluxation and its association with subscapularis tendon rupture. Results: According to the arthroscopic results, the subscapularis tendon injury was present only in 21.2% of the evaluated cases. The biceps subluxation in magnetic resonance images has a sensitivity of 71.4%, while the superior glenohumeral ligament (SGHL) lesion is 85.7%. Conclusion: Preoperative magnetic resonance (MRI) that are evaluated in a systematic way have a diagnostic accuracy of 78.79%.
