For a radial head dislocation, doctors usually advise surgery in case of adults and closed reduction in the case of children.

[2] Forearm fractures and dislocations, especially in children, are often misjudged, and it is important to maintain a high index of suspicion for these injuries in patients presenting after elbow and arm trauma. Reduction of Chronic Radial Head Dislocation Chronic dislocation of the radial head is rare and often goes undiagnosed. Elbow arthrocentesis is a minor procedure that involves removing the fluid (synovial fluid) from the elbow joint cavity through a needle (aspiration) The aspirated fluid is then sent to a lab for further analysis. When dislocations of the radial head occur in infancy, the diagnosis may be missed, resulting in chronic radial head dislocation. Make helpful changes to manage your chronic condition. The radial head may be palpable in an anterolateral or posterolateral location, and the forearm may appear shortened and angulated. Hand Clin.
