First-aid treatment of joint dislocation
If the ambulance person is not familiar with the repositioning technique, do not rush to try to reset it so as not to increase the pain of the wounded and even increase the injuries of the organization. At this time, it can be fixed in the original position to maintain stability, local cold compress, and then sent to the medical unit for treatment.
As a general dislocation, the ambulance person can be reset and can also be performed on site. The principle of reset is to relax the local muscles, and pull them in the opposite direction according to the force at the time of injury. First, they should be pulled apart and then rotated.

The ambulanceman first wrap the thumb of both hands on the gauze and put it on the cheek teeth on both sides of the other side. The thumb oppresses the cheek teeth on both sides. The other four fingers hold the jawbow and lift the chin and push it upwards. The thumb slides out of the teeth. At this point, a sliding sound can be heard, indicating that it has been reset. After the reset, the upper and lower teeth of the wounded can be aligned and can open their mouths freely, but they should not open their mouths within one month.
2. Dislocation of the shoulder joint: The typical symptom is a flat square shoulder. There is a depression below the shoulder peak, and you can touch the head of the humerus. The patient's hand cannot stick to the chest to touch the other shoulder.
