For patients with bone dislocation, the best time for reset is as follows: 1, if the joint is dislocated, it should be reset as soon as possible after the injury, so as not to cause spasm of the joint capsule ligaments for a long time without resetting, which will lead to the tension of the joint parts, which is not conducive to the reset treatment; 2, if the patient’s bone dislocation is caused by a fracture, the best time to reset is within one week after the fracture, if it is more than one week the fracture end will gradually have a fibrous If more than a week the fracture end will gradually have the formation of fiber connection, it will be relatively stable, thus it will be unfavorable to the reset of the bone. Therefore, if the bone is dislocated is the case of joint dislocation, the best time to reset is 6-8 hours after dislocation, if the fracture caused by the fracture must be carried out within a week of the fracture reset.
