How is a clavicle fracture typically treated?

Strap or surgery. If there is minimal displacement then a clavicle strap is enough. If markedly displaced, then surgery would be appropriate. This would include a plate and screws or a small rod that would be placed inside the bone after aligning it.
Non op or surgery. Clavicle fractures without much displacement or shortening are treated without surgery usually in a sling for comfort for a week or two then early range of motion of the shoulder. Displaced or shortened clavicle fractures may be treated with surgery. .
