The repositioning technique of joint dislocation is different depending on the location and joint. The same thing is that no matter which joint is dislocated, the appropriate technique is chosen according to the direction of dislocation and the position of the bone end. First, the principle of rectification is to increase the dislocation along the direction of dislocation, which is called the desire to close first, and then to rectify. Second, the original way back, the original way back is from which off, the rectification of the time to let back from where. Third, the role of leverage, that is, in the rectification, can not be violent, the use of leverage to let it back to the position. After some dislocations, the patient’s pain is particularly intense, and when the muscle is strongly contracted, there is no way to rectify the dislocation, so it is necessary to do relaxation techniques, or local anesthesia treatment, and then rectify the dislocation after anesthesia.
