Reason: eval for Tendonitis; arthritis; joint inflammation History: decreased ROM elbow joint; pain; swelling LIGAMENTS: The ulnar collateral ligament appears intact. The radial collateral ligament appears intact. The lateral ulnar collateral ligament appears intact within the limitations of a non arthrogram study.TENDONS: There is increased signal abnormality within the common extensor tendon at the level of its origin from the lateral epicondyle indicating moderate tendinosis. Additionally, there is linear fluid signal abnormality within the common extensor tendon indicating a partial thickness tear (image 15; series 601). Some of the fibers of the common extensor tendon can be traced to the level of their origin on the epicondyle. There is no significant retraction. The biceps tendon appears intact. The brachialis tendon appears intact. There is intermediate signal intensity within the triceps at the level of its insertion on the olecranon indicating a mild tendinosis. The tendon itself appears intact.ARTICULAR SURFACES AND BONE: There is a moderate amount of fluid within the elbow joint with some foci of low signal intensity internally suggesting a synovitis. Note is made of multiple foci of low signal abnormality within the joint with the largest situated along the medial aspect of the olecranon, measuring 6 mm in the transverse dimension (image 22; series 501) consistent with loose bodies. There is an additional loose body identified within the ulnotrochlear articulation (image 14; series 1001). There is osteophyte formation indicating mild to moderate osteoarthritis of the elbow . There is full-thickness articular cartilage degeneration along the lateral aspect of the trochlea with underlying degenerative subchondral signal abnormality. There is partial-thickness articular cartilage degeneration along the medial aspect of the radial head.SURROUNDING STRUCTURES: The imaged musculature of the elbow is normal in appearance. There is perhaps minimal increased signal abnormality surrounding the ulnar nerve as it courses through the cubital tunnel which is nonspecific but may represent a very mild neuritis.ADDITIONAL
1. Partial thickness tearing and tendinosis of the common extensor tendon without significant retraction as described above.2. Moderate-sized elbow joint effusion with multiple loose bodies as well as findings suggestive of a synovitis as described above.3. Osteoarthritis of the elbow. Other findings as described above.
