38-year-old male with possible elbow MCL tear status post fall. Evaluate for pain and swelling. LIGAMENTS: There is disruption of the proximal fibers of the radial collateral ligament. The ulnar collateral ligament appears intact. The lateral ulnar collateral ligament is poorly visualized and may be disrupted.TENDONS: There is discontinuity of the proximal fibers of the extensor digitorum tendon just distal to its origin off of the lateral epicondyle indicating a tear. There is increased signal abnormality and deformity of the remainder of the common extensor tendon indicating at least partial thickness tearing. Some of the fibers of the common extensor tendon to be traced to their insertion on the lateral epicondyle. The common flexor tendon appears intact. The biceps and brachialis tendons appear intact. The triceps tendon appears intact. ARTICULAR SURFACES AND BONE: There is a minimally displaced fracture of the coronoid process with slight inferior displacement of the volar fracture fragment. There is increased bone marrow signal abnormality on fluid sensitive sequences about the sublime tubercle and in the surrounding area likely representing a minimally depressed (2 mm) impaction fracture. There is increased bone marrow signal abnormality within the lateral aspect of the radial head likely representing a direct bone contusion.SURROUNDING STRUCTURES: There is increased signal abnormality on fluid sensitive sequences within the ulnar nerve within and proximal to the level of the cubital tunnel which likely represents a mild neuritis perhaps related to the patient's history of trauma. There is mild increased signal abnormality within the flexor digitorum profundus and flexor carpi ulnaris which may be related to the patient's history of trauma/inflammation, although subacute denervation cannot be excluded. There is subcutaneous edema in the overlying area.ADDITIONAL
1. Disruption of the radial collateral ligament, lateral ulnar collateral ligament, and extensor digitorum tendon with additional partial thickness tearing of the remainder of the common extensor tendon as described above.2. Fracture of the coronoid process as well as a minimally depressed impaction fracture about the sublime tubercle of the ulna.3. Bone contusion of the radial head.4. Moderate size elbow joint hemarthrosis. Other findings as described above.
