Clavicle nail is an internal fixation device applied to clavicle fracture. Usually, the clavicle nail is penetrated into the clavicle medullary cavity through one end of the clavicle, and then through the fracture break to achieve the effect of fixing the clavicle, especially for the clavicle fracture in adolescents, especially for the clavicle nail internal fixation surgery. Because of the abnormally rapid growth of the adolescent body, if a plate is applied for internal fixation, because the length of the plate is fixed, but with the growth of the clavicle, the plate may break off the screw, while using the clavicle nail for intramedullary fixation, there is no such risk. However, the clavicle nail also needs to be removed. Generally, after the fracture heals, usually after six months to one year, consider removing the clavicle intramedullary nail, and after removing the intramedullary fixation, you can resume normal activities after resting for about two weeks.
