- Aceramic-on-ceramic bearing coupling, because of its
qualities of reduced friction and wear, is an attractive
alternative bearing surface in total hip arthroplasty.
The use of such bearing couplings is likely to reduce problems
related to polyethylene wear debris1-6. Osteolysis has only
rarely been reported in association with ceramic-on-ceramic
bearing couplings, and reports are generally limited to cases
involving early generation ceramic bearings or loosened prostheses7,8.
Recently, several cases of osteolysis have been reported
after total hip arthroplasty with use of a contemporary
alumina bearing, but these reports only described the femoral
scalloping seen on radiographs and did not present any histological
evidence that ceramic particles were the causative
factor9. We present the case of a patient who had formation of
a large amount of osteolysis about both the acetabulum and
the proximal part of the femur, induced by ceramic wear
particles from a well-functioning contemporary alumina-onalumina
total hip prosthesis. The patient was informed that
data concerning the case would be submitted for publication,
and she consented.
