Our experience of a ceramic on ceramic surface bearing combination with noncemented
hip prosthesis starts from 2001, number of patients: 37. Retrospective
clinical and radiological analyses were performed on 37 patients with femoral SRL
(Zweymuller) prosthesis stem in combination with Biolox forte head and press fit
Duraloc (DePuy) metal backed acetabular component matched with ceramic Biolox
forte insert. Patients age groups 18-30 years (3 pts), 31-40 years (7 pts), 41-50 years
(13 pts), 51-60 years (10 pts), 61-70 years (4 pts). Clinical evaluation - Harris hip
score pre operation, 1-3 and 4-6 years post operation. Radiological evaluation - AP
and LL X-ray early, 1-3 years and 4-6 years post operation. Average Harris hip score
result before operation was 40-60 points, 1-3 years after operation 96-98 points, 4-6
years after operaton 94-96 points. No signs of osteolytic changes around the
acetabular component in patients groups 1-3 and 4-6 years after operation were
found according to Charnley De Lee zones, and the abscence of radiolucent lines is
characteristic for prosthesis stems in both patients groups. Combination noncemented
hip implant and ceramic on ceramic bearings can be reasonably proposed
for younger patients who are looking for minimal restrictions in the quality of life by
reducing the number of revisions as far as possible.
