[Total hip prosthesis. Current indications (author's transl)]

The various problems posed by total hip prosthesis are first described. The authors then analyse the various parameters which should guide the choice of this technique which must be used only when all other solution have failed. The recent development of prostheses without cement has made it possible to widen the application of this surgery to younger patients. Two special cases are finally reported: the role of total prostheses in the treatment of sequelae of fractures of the acetabulum, and in disarthrodesis of the hip with insertion of a total prosthesis.
