After a joint dislocation, there will be localized impairment of joint movement, pain, and swelling. For joint dislocation, it is necessary to seek medical attention early and carry out joint resetting, the earlier the resetting, the smaller the damage caused. There are several signs of successful joint resetting: First, a popping sensation can be felt when the joint is resetting, and a popping sound of the joint entering the socket can be felt. Second, the pain in the dislocated shoulder joint can be significantly relieved, which indicates that the joint may have been repositioned. Third, the joint will not be deformed after reset. Fourthly, in patients with mild symptoms after resetting, the injured joint can be moved on the spot and no obstruction is felt when moving. Fifth, for example, if the shoulder joint is dislocated, there is a shoulder hitch test, which means that the injured hand is placed on the opposite shoulder and the elbow joint can be pushed to the chest. Sixth, in the hospital, the doctor will usually take a picture of the patient, and the picture will clearly show whether the joint has been reset.
