The age of the fracture and the degree of displacement of the fracture are the main determinants: preschoolers (0-6 years old): surgery is usually not necessary unless there is a combination of vascular or nerve damage. Even if the fracture is displaced, there is no need for special immobilization, just a 3-week suspension with a tricot or scarf. The fracture may bulge locally in the early stage of healing, and the shoulder on the side of the fracture may become narrower, but these are nothing to worry about. Children (7-12 years old): Surgery is usually not required, but can be done by repositioning the fracture manually and then fixing it with a clavicle fixation band or cast for 4 weeks. Adolescents (13-18 years old): If the fracture is not significantly displaced, it can also be repositioned by manipulation and fixed with a clavicle fixation band for 6 weeks; if the displacement is significant (fracture displacement greater than 1 cm), surgery can be performed, preferably with a minimally invasive approach, making a small incision to help reset the fracture and then fixing it with an elastic intramedullary nail. Adults: Clavicle fractures with a fracture displacement of less than 1 cm usually do not require surgery and can heal in 6 weeks with a clavicle fixation band. However, for clavicle fractures with a displacement greater than 1 cm. (1) the fracture is prone to non-healing, resulting in pain and limb weakness; (2) the affected shoulder becomes narrower, which affects the aesthetics. Therefore, surgery is needed because the fracture healing ability of adults is poorer than that of adolescents, so fixation should be done with a stronger plate fixation.
