Elbow dislocations are usually caused by severe trauma and may be combined with periarticular fractures or tears of tendons. Treatment can be divided into conservative and surgical treatment. Conservative treatment is mainly for new dislocations of the elbow joint that are not too serious, which can be repositioned by manipulation and fixed in a cast after the repositioning treatment. For old elbow dislocations that are more than three weeks old, you can also try manual repositioning and fixation treatment, if the effect of manual repositioning is not good, surgery is recommended. Surgical treatment is mainly for cases of failed manual repositioning or serious injury to the elbow joint or elbow dislocation combined with an avulsion fracture of the medial humeral epicondyle or old elbow dislocation. Surgery can be performed by open repositioning or arthroplasty. After surgery, a cast should be applied. The cast should be removed after a period of immobilization and the amount of elbow movement should be gradually increased to promote the recovery of the elbow joint function. Regardless of whether the treatment is conservative or surgical, after a period of external fixation, in order to promote the recovery of elbow joint function, in addition to gradually increasing the amount of joint movement, rehabilitation measures or physical therapy can also be used to improve the movement of the elbow joint. In conclusion, for elbow dislocation, immediate hospital treatment should be performed to determine the type of elbow dislocation and whether there is a combination of fractures, etc., and then choose a reasonable treatment plan according to the specific situation.
