The treatment of radial tuberosity subluxation includes manipulative repositioning, plaster immobilization, surgical treatment and so on. 1. Manipulation: the reset person can use one hand to hold the elbow of the dislocated person, the thumb touches the position of the radial tuberosity, the other hand holds the wrist or forearm of the dislocated person, and then the forearm rotates quickly, both of them coordinate the force at the same time, and bend the elbow rapidly, if you can hear a popping sound or there is a popping sensation at the radial tuberosity, then it is regarded as the reset is successful. 2. Plaster immobilization: the first time the person who reset the radial tuberosity does not need to be immobilized, but for the repeated radial tuberosity subluxation, the person who reset the radial tuberosity should be immobilized with plaster for about 7 days to prevent the affected limb from being pulled. 3. Surgical treatment: For the treatment of old dislocation, the specific surgical plan should be made according to the age, length of the dislocation and radius, and the relationship of the phalanges. When semi-dislocation of radial tuberosity occurs, it should seek medical treatment in time and standardize the treatment under the doctor’s guidance, avoiding self-replacement and delaying the condition.
