[Surgical technical treatment of the acetabulum in hip joint replacement. Evaluation of an acetabulum-preserving surgical technic based on a 10-year follow-up study].

The results of a 10-year follow-up examination of acetabular components in hip joint replacement following a protective acetabulum operating technique are demonstrated. With the exception of 4 cases in which during the operation the integrity of the acetabulum was not sufficiently observed, 90 per cent of the acetabular implants were on hand from x-rays fully integrated. A remarkable bone cement demarcation was to be found only in 10 per cent but there were no signs of loosening. The authors emphasize a protective acetabulum operating technique with special care to avoid the weakening of carrying structures of the acetabulum.
