11+ Biceps Tendon Anatomy Shoulder. A complete ultrasound examination involves evaluating the four major tendons of the rotator cuff (biceps, subscapularis, supraspinatus and infraspinatus), the subacromial subdeltoid bursa and the acromioclavicular joint. Biceps tendonitis, also called bicipital tendonitis, is inflammation in the main tendon that attaches the top of the biceps muscle to the shoulder.
In general, these injuries occur more frequently as we become older.
The long biceps tendon arises from the supraglenoid tubercle and partly from the superior glenoid labrum (7a). If you tear your biceps tendon at the shoulder, you may lose some strength in your arm and have pain when you forcefully turn your arm from palm down to palm up. When left untreated, chronic biceps tendonitis can lead to degeneration and tearing, which may require surgery to restore function and alleviate pain. Your biceps tendons attach the biceps muscle to bones in your shoulder and in your elbow.
