The clavicle is a long "S" shaped bone that connects the sternum to the shoulder blade. Clavicle fractures are common, especially in children. In many cases, these fractures heal on their own over time, thanks to immobilization with a splint. However, in some cases, surgery may be necessary to stabilize the bone fragments, especially if there is significant displacement or if the fracture involves other structures such as nerves or blood vessels.
