The severity of a comminuted clavicle fracture depends on the patient’s age, general condition, and the cause of the trauma. If the cause of most comminuted clavicle fractures is due to a sudden high-energy injury, such as a high fall injury, a car accident injury or a heavy object, and the cause of a comminuted clavicle fracture is more serious. If the patient is a child, the fracture is usually a green branch fracture, which is not serious because of the plasticity of children. If the fracture is not displaced, it can be fixed by suspension with a figure-of-eight bandage, and if it is displaced or angular, it can be fixed by suspension with a figure-of-eight bandage or by external fixation with a plaster cast. In case of adult clavicle comminuted fracture without displacement, the fracture is not serious and can be fixed with external plaster for 6-8 weeks. If the fracture is significantly displaced or angular, the fracture can be internally fixed by fracture dissection and suspended by triangular scarf after surgery, which is not serious.
