AP (a) and attempted lateral (b) radiographs of the right elbow demonstrating anteromedial elbow dislocation in a skeletally immature individual. The solid arrow points to the Salter-Harris radial head fracture with significant radial head displacement. The dashed arrow points to an ossific fragment near the distal humerus which likely represents the olecranon avulsion.

X-ray evaluation revealed an anteromedial elbow dislocation with fracture of the radial head (Figure 1).
Lateral radiograph of the right elbow showing continued anterior dislocation of the ulnohumeral joint despite attempted reduction. The Salter-Harris II fracture of the radial head can again be noted.

Once under general anesthesia and with muscle relaxation employed, another closed reduction maneuver was attempted again with no success (Figure 2).
AP (a) and lateral (b) radiographs of the right elbow demonstrating anatomic reduction of both the ulnohumeral and radiocapitellar joints. The radial head fracture has improved alignment.

Once the entrapped proximal ulna was freed from the anterior capsule, it was easily reduced into its anatomic position (Figure 3).
AP (a) and lateral (b) radiographs of the right elbow 7 months postoperatively demonstrating continued anatomic reduction of the ulnohumeral and radiocapitellar joints. The radial head and olecranon fractures are well healed. The patient's physes remain open.

Radiographs revealed well aligned and healed fractures with maintained physes (Figure 4).
