The screwed acetabulum in acetabular reimplantations: long-term results.
The authors report the method used and long-term results for 61 acetabular reimplantations involving screwed truncated-conical acetabula and bone grafts. Mean follow-up was 6.3 years. From a clinical point of view the cases classified as excellent were 14 (24.1%), good 26 (44.8%), fair 12 (20.7%), and poor 6 (10.4%). As for radiographic evaluation, the acetabulum appeared to be stable in 37 cases (63.8%), there was fibrous stability in 13 cases (22.4%), the radiographic findings had shown uncertain stability in 5 cases (8.6%), and the acetabulum was unstable in 3 cases (5.2%). Long-term results show that the biological stabilization and, in particular, the implantation of screwed acetabula, when technically correct, may constitute a valid solution in revision surgery for the acetabular component.
