Whether the arm can be lifted in one month after the clavicle fracture depends on what kind of treatment and the patient’s functional exercise, if the surgery is used for internal fixation treatment, the patient can lift his arm if he exercises early and well, if the conservative treatment is used, he can’t lift his arm in one month because of the failure of early functional exercise. Clavicle fracture generally use non-operative treatment and surgical treatment, surgical treatment due to internal fixation, the fracture is not easy to displacement, can be early functional exercise, if the exercise is sufficient, the arm can be lifted in a month, but need to pay attention to avoid amplitude overloading and weight-bearing, etc., to avoid causing re-fracture. Clavicle fracture non-surgical treatment, need early external fixation and braking, long-term inability to move the shoulder joint will lead to joint adhesion, shoulder joint function with the use of waste, will lead to joint function limitation, external fixation is generally need to be fixed for about a month, within a month the shoulder joint can not be moved, the arm naturally can not be lifted.
