Elbow pain Examination is limited by motion artifact and by the patient's body habitus.Imaging was performed from the humeral head through just distal to the elbow. The images demonstrate an absent extra-articular portion of the biceps tendon within the intertubercular groove. There is marked atrophy of the long head of biceps particularly proximally with with atrophy also noted along the myotendinous junction. There is also mild muscle edema about the myotendinous junction which may represent subacute atrophy or edema. The biceps insertion upon the radial tuberosity is intact. The marrow signal of the humerus is normal. The signal and caliber of the remaining are musculature is normal.
Marked atrophy of the long head of the biceps proximally with fatty atrophy extending through the myotendinous junction, the result of proximal biceps tendon rupture.
