1.Active exercise After the joint swelling subsided and the incision pain was relieved, active extension and flexion functional exercise was done 2 d~3 d after surgery. Every 0.5 h active extension and flexion, the movement should be smooth and slow, as far as possible to reach the maximum amplitude, the force to cause mild pain as the degree. Patients control the intensity of force according to the pain sensation, so as not to cause injury. In the functional exercise, sometimes there may be increased pain, swelling, etc., rest and then carry out, so that when the patient is discharged from the hospital in 2 weeks, the basic reach or close to the range of motion at the time of surgery. 2.Passive movement When the active movement makes the affected limb flexion and extension to the limit, then the opposite side of the healthy hand to be passive activities, in order to stretch bending adhesion tissue. However, the degree of force should be controlled according to the patient’s pain, to avoid causing obvious pain, and not to exert violence, so as not to cause new injuries. 2 to 4 times a day, 20 to 30 times each time. 3.Joint function traction The patient sits on the chair, fixes the elbow joint on the special armrest, the forearm and upper arm are rotated empty, hangs a sandbag in the forearm traction, exercises straightening, with a rope set in the wrist, hangs on the back of the chair with a pulley to traction behind the pillow, exercises flexion, once or twice a day, for 10 min ~ 20 min, can better traction contracture and adhesion of fibrous tissue, so as to more effectively restore joint mobility. 4.Postoperative medication Anti-inflammatory and analgesic 25 mg, 3 times a day for 2 weeks, can suppress pain and traumatic inflammation and help to restore the function of the elbow joint. 5.Discharge instruction Functional exercise, mainly active extension and flexion, supplemented by passive exercise. The frequency can be accelerated, 1 min to 3 min once, 30 to 50 times of flexion each time, according to the patient’s specific situation, respectively. Elbow joint dysfunction is one of the most common complications after elbow fracture. The severity of adhesions depends on the degree of original injury, the size of surgical trauma, the solidity of internal fixation, the length of external fixation and the subjective factors of the patient. The pathological changes that cause joint dysfunction are: 1. extra-articular factors: adhesions between the muscle and periosteum of the anterior joint capsule of the elbow joint, scar contracture of the fibrous surface of the humerus, ossifying myositis, etc.; 2. intra-articular factors: adhesions between the cartilage and the joint capsule after the fracture, unevenness of the joint surface, deformed healing of the fracture, blockage of bone disease, etc.; 3. mixed factors: bleeding of the joint, intra-articular If there is bleeding in the joint, intra-articular fracture, flexion contracture of fibrous adhesions, or damage to the joint, the release surgery may not be ideal. It has been observed that 4 d of joint fixation can result in histological signs of contracture, and 4 weeks of fixation of normal joints can result in reduced or lost joint mobility. Injured joints begin to lose mobility after immobilization, with most mobility impairments recovering spontaneously after 3 weeks of immobilization, recovering slowly after 40 days of immobilization, and may not recover spontaneously after 60 days of immobilization. Braking can reduce the strength of ligaments, and the ability to absorb and cushion stress is also reduced due to muscle atrophy. Atrophy and contracture of articular cartilage also reduce the ability to disperse and cushion stress. Therefore, we should pay attention to rehabilitation training after surgery, emphasizing early, less painful and active functional exercises. Active exercise can strengthen the muscles, activate the blood circulation of the limbs and eliminate swelling. Functional joint traction can be used for a certain period of time to better stretch the contracted and adherent fibrous tissues, thus restoring the joint mobility more effectively, and the CPM machine can also be used to assist the exercise. Simultaneous application of anti-inflammatory pain for 2 weeks can reduce the patient’s pain and inhibit scarring and osteoarthritis. Thus, surgery and early rehabilitation are the most effective methods to resolve elbow adhesions.
