The main exercise methods after removing the cast of the fracture include local physical therapy and proper movement of the joint. Fracture cast external fixation usually covers the neighboring joints at the fracture site. Prolonged braking will cause muscle atrophy, joint stiffness and other complications, so it is necessary to go through scientific and reasonable exercise to recover. 1. Local physical therapy: such as local hot compresses, acupuncture and massage, etc., will reduce the adhesion around the fracture or joint and increase the mobility of the limbs. 2. Appropriate activity of joints: when the joints become stiff, they should be moved appropriately. At first, the activity should not be too big and too frequent, but should be gradual and progressive, the amplitude and frequency should be increased gradually, so as to make the surrounding soft tissues loosened gradually, and when the activity is recovered completely, regular and quantitative regular exercises should be done, so as to restore the muscle strength. Plaster external fixation is a common treatment in orthopaedics, but whether it is plaster fixation or removal of plaster, do not do it by yourself, it should be carried out under the guidance of professional doctors.
