[Arthroplasty of the hip by cemented coupled cups. A new technique (author's transl)].

A presentation of a technique of arthroplasty using cemented coupled cups which has been used in 50 cas over a period of more than a year. The hip is approached via an anterolateral incision with the patient in a dorsal horizontal position. This cemented cup arthroplasty has all the advantages of a classical total prosthesis: solid fixation, minimal rubbing by the use of a metal head and an acetabulum in high density polyethylene. However, it has none of the disadvantages since little cement is used, the medullary cavity is not opened and, above all, the neck of the femur is preserved, thereby rendering possible any later operation which may be necessary. The technique is described in detail and the indications rapidly reviewed.
