[Dislocation of a total hip prosthesis: etiology and treatment].
Dislocation of a total hip prosthesis is a substantial burden in terms of morbidity and health care costs. The incidence of dislocation is highest during the first postoperative months but the risk persists throughout the entire life of the patient. The first dislocation is treated by an emergency closed reduction of the hip undergeneral anaesthesia, following which about three out of four patients will have a stable hip. In cases of recurrent dislocation the treatment is difficult, depending upon the time between surgery and dislocation, the identification of an etiologic factor, and the general status of the patient. Patients in which a specific cause can be identified have better results after surgical revision. When no causal factor is detected several surgical options are possible, but the results are less consistent.
