Male, 69 years old. Biceps tendon rupture Evaluation of the elbow is limited by patient motion artifact. Furthermore, the patient refused further imaging to delineate the proximal extent of muscle retraction.LIGAMENTS: The anterior band of the ulnar collateral ligament as well as the radial collateral ligament proper appear intact. The lateral ulnar collateral ligament is difficult to visualize, but we suspect it is intact.TENDONS: Although a very thin (submillimeter) slip of biceps tendon can be traced to its insertion on the proximal radius, the remainder of the tendon has detached from the radius and retracted proximally by several centimeters to the lacertus fibrosis at the level of the humeral epicondyles. This appears to be a chronic, essentially complete tear of the biceps, as no edema is seen along its expected distal course. The brachialis muscle and tendon are intact. The triceps tendon is intact. The common flexor and common extensor tendons are intact.ARTICULAR SURFACES AND BONE: Bone marrow signal intensity is normal. The elbow joint appears normal for age. SURROUNDING STRUCTURES: There is mild subcutaneous edema superficial to the medial epicondyle. The remaining soft tissue structures are normal.
Limited study as described above showing an essentially complete, chronic tear of the distal biceps tendon.
