Pinned collar bone fracture. Coloured X-ray of the shoulder of a 24 year old man, showing pinning of a fracture of the collar bone (clavicle). A metal plate (yellow) has been surgically screwed into the clavicle to join the fractured ends of bone and immobilize it. The broken shoulder will be rested to allow the bone and soft tissues to heal. The upper arm bone is seen at lower far left; below the clavicle is the shoulder blade (scapula, at left); ribs of the ribcage are at lower right. This is a sports injury, such as may occur when playing rugby.
