Indications and limits of hybrid hip prostheses (cementless acetabulum and cemented stem).

The authors report the indications and short-term results obtained in a series of 99 total hip prostheses with a screwed acetabulum and cemented stem. The principles which inspired their choice and the criteria used to select patients are discussed. The results obtained, evaluated both clinically and radiographically, are satisfactory, particularly with regards to percentage of pain symptoms in the femur.
