ABSTRACT
Pain may be felt diffusely on the medial side of the joint, the posterolateral side or acutely localized to one of the humeral epicondyles. Pain over the back of the elbow is often due to an olecranon bursitis. Magnetic resonance imaging is used mainly for the investigation of soft-tissue lesions around the elbow such as ligament tears and tendinopathies. The addition of arthrography improves sensitivity for detecting loose bodies and chronic ligament lesions. Varus deformity is most obvious when the elbows are extended and the arms are elevated. The deformity itself needs no treatment, but for delayed ulnar palsy the nerve should be transposed to the front of the elbow. Although the disease begins as synovitis or osteomyelitis, tuberculosis of the elbow is rarely seen until arthritis supervenes. The cardinal clinical feature is sudden locking of the elbow.
