Purpose: To evaluate the radiographic and clinical results of 66 total hip arthroplasties with Hams-Galante 2 acetabular cup.
Material and Method: The results of 66 total hip replacements with a non-cemented HarrisGalante 2 acetabular component were analyzed. The average follow up period was 6 years (range, 4 to 9 years). The pre-and post-operative Harris hip scores were measured. For radiologic evaluation of the acetabular components, radiolucent line, osteolysis, change of inclination of the acetabular cup and vertical distance were checked. The wear of the polyethylene liner was measured by the Livermore method.
Results: The Hams hip score improved from 54 points preoperatively to 95.6 points at the recent follow up. Ten hips (14.9%) demonstrated osteolytic lesions around the cup. Sixty-four hips (97%) were considered radiographically stable and two hips (3%) were unstable. There were 6 revisions of the acetabular component: two for aseptic loosening, two for locking mechanism breakage and dissociation of the polyethylene liner, and two for locking mechanism breakage and excessive wear of the polyethylene liner. In another hip, only the polyethylene liner was exchanged. The average total wear amount of the polyethylene liner was 0.86mm with a rate of 0.18mm/year.
Conclusion: Non-cemented acetabular fixation with the Hams-Galante 2 component showed excellent or good clinical results at average 6 years follow up. As follow up increases, aseptic loosening, locking mechanism breakage, wear of the polyethylene liner and periprosthetic osteolysis may become increasing.
