Fractures of the clavicle commonly occur after a fall on the shoulder. For a long time, these fractures were simply immobilised, even if the fracture was greatly displaced. In adults, some fractures can heal poorly or result in poor functional outcomes if the clavicle heals in a non-anatomical position. Even if immobilisation alone can be proposed in most cases, surgical treatment with a plate ensures better healing and improves the anatomical, functional and aesthetic outcome.
