  • Figure 1
    Conventional radiograph of the right elbow, lateral and anteroposterior view
     

    The capitellum has a slightly irregular articular contour (white arrow) and there is a radiolucent crescent in the subchondral bone (black arrows). Note slight joint effusion with displacement of the elbow fad pads...
