In the early stage, when the fracture is fixed, swelling and pain are the most important signs and symptoms after fracture reduction, and persistent swelling is the most important cause of disability after fracture. Therefore, the goal of early treatment is mainly to eliminate swelling and relieve pain. 1. Active exercise: It is the most effective, feasible and least expensive method to eliminate edema. Active exercise helps venous and lymphatic return. (1) Active movement in all axial positions of the injured limb proximal and distal to the unanchored joint, with assistance if necessary. 2) Rhythmic isometric contraction exercises of the muscles of the area at the site of fracture fixation to prevent disuse atrophy and to facilitate fracture healing by compression of the fracture end. (3) Intra-articular fractures, often leaving serious joint dysfunction, in order to reduce the degree of impairment, after 2-3 weeks of fixation, the external fixation device should be removed daily for a short time if possible, and the active movement of the damaged joint without weight bearing should be performed under protection, and the range of motion of the joint should be gradually increased, and the fixation should continue to be maintained after the movement. d. The normal activity of the healthy limb and the drive stem should be maintained as much as possible, and the patient should get up as early as possible if possible. Patients who must be bedridden should do bedside exercises daily to improve the general condition and prevent complications such as pressure sores and respiratory system disorders. 2. Elevation of the affected limb: It helps the swelling to subside. In order to make the elevated limb effective, the distal end of the limb must be higher than the proximal end and the proximal end should be higher than the heart level. 3, other physical therapy: such as warmth therapy: conduction heat therapy, radiation heat therapy. Ultra-short wave therapy or low-frequency magnetic therapy. However, it is prohibited when there is metal plate internal fixation. Audio electric or ultrasonic therapy.
