Very little investigation has been undertaken into the microvascular bed of the rotator cuff. Lindblom (1939) described areas of relative avascularity in the supraspinatus tendon adjacent to its point of insertion, and a similar zone in the long head of the biceps near its origin from the supraglenoid tubercle. Moseley and Goldie (1963) also noted a zone of diminished vascularity near the inser...

The rotator interval of the shoulder joint is located between the distal edges of the supraspinatus and subscapularis tendons and contains the insertions of the coracohumeral and superior glenohumeral ligaments. These structures form a complex pulley system that stabilizes the long head of the biceps tendon as it enters the bicipital groove of the humeral head. The rotator interval is the site ...

Shoulder pain is one of the most common musculoskeletal complaints in clinical practice. Ultrasonography a useful method for diagnosis various shoulder diseases and injuries. This article presents ultrasonographic features conditions, including those affecting rotator cuff, long head biceps, subacromial-subdeltoid bursa, glenohumeral acromioclavicular joints.

The use of shoulder ultrasound as an imaging modality has recently gained widespread attention; however, the ability of ultrasound to diagnose long head of the biceps tendon pathology accurately still remains unclear. The biceps tendons in 71 patients were prospectively evaluated by comparison of standard ultrasonographic and arthroscopic examinations. Arthroscopic examination was used as the g...

Because of difficulties in diagnosis of pathology of the long head of the biceps tendon and a desire to prevent later complications, there may be a tendency to perform a biceps tenodesis even when pathology is mild. Surprisingly, in this multivariate analysis of a large database, tenodesis of the biceps was associated with increased odds of revision rotator cuff repair. Although the statistical...

It has been suggested that the positive position of the O'Brien test (shoulder flexion, horizontal adduction, and internal rotation) tensions the bicipital labral complex relative to the negative position (shoulder flexion, horizontal adduction, and external rotation). This study measured active and passive tension in the long head of biceps in the 2 positions of the O'Brien test to validate th...
