Surgery for left clavicle acromioclavicular fracture usually takes 2~3 months to lift. If the left clavicle acromioclavicular fracture is displaced, internal fixation with Kirschner’s pin is adopted, and if the fracture heals well, Kirschner’s pin can be removed for rehabilitation exercise, and minor patients can be lifted in about 2 months. The amplitude of lifting should not be too big at the beginning, and it should be gradual. If it is a comminuted fracture with ligament damage, the plate screw fixation, the recovery is slow, usually about 3 months before the arm can be lifted. When lifting, there is a slight pain, joint activity is limited, through exercise can gradually return to normal. How long it takes to lift the arm after surgery for left clavicle acromion fracture depends on the surgical method and the healing process.
