Lateral radiograph of the adult elbow

This lateral radiograph shows normal elbow alignment. A line extended along the anterior border of the humerus (8) or through the middle of the shaft of the radius would bisect the capitellum (2). The structures shown include: humerus (1), olecranon (3), coronoid process (4), radial head (5), radial neck (6), radial tuberosity (7), and the olecranon fossa (9), which is not well seen on the lateral view.
