Elbow joint dislocation methods include simple flexion reset method, first extension and flexion activities and then flexion reset, surgical incision reset and so on. 1. Simple flexion method: this method can be used for those who have just dislocated or dislocated for a short period of time. The dislocated person takes the sitting position, after local anesthesia, an assistant fixes the upper arm of the dislocated person, the reset person holds the wrist of the dislocated person tightly, flexes the elbow joint by 60°～90°, and pushes and presses and lifts with force with the elbow joint as the point of force, and the manipulation should be rapid, and the reset is successful when the reset sound is heard. 2. Extension and flexion activities and then flexion reset: for elbow dislocation for a long time or old dislocation, may have occurred in the joint capsule adhesion, can choose this method. After local anesthesia, the dislocated person should do elbow extension and flexion activities gently, and then let him/her flex the elbow gently for 60°～90°, the reset person presses the position of hawksbill of the elbow with both hands, and at the same time push the lower end of the humerus to the back with the force. 3. Surgical incision and reset: For those who fail in manipulative reset and those who have elbow dislocation with fracture around it, surgical incision and reset is usually performed to achieve anatomical reset of the elbow joint. In addition, after X-ray to determine the success of the reset, make the elbow joint bend about 90 °, use the plaster cast fixed in front of the chest, after about 2 ~ 4 weeks can be removed from the plaster, and rehabilitation exercises. When elbow dislocation occurs, you should immediately seek medical treatment under the guidance of a doctor, and should not reset the elbow without authorization.
