Insights
This study shows a stemmed acetabular component effectively treats severe hip joint deficiency in revision and complex primary total hip arthroplasty, with excellent long-term survival rates and minimal revision needs.
Area of Science:
- Orthopedic Surgery
- Biomedical Engineering
- Arthroplasty Research
Background:
- Severe acetabular deficiency poses challenges in total hip arthroplasty.
- Revision and complex primary cases require robust reconstructive solutions.
Purpose of the Study:
- To evaluate the efficacy and long-term outcomes of a stemmed acetabular component.
- To assess its use in severe acetabular deficiency during revision and complex primary total hip arthroplasty.
Main Methods:
- Retrospective analysis of 31 hips treated with a stemmed acetabular component.
- Included 24 revision (aseptic loosening, infection) and 7 complex primary total hip arthroplasties.
- Follow-up averaged 10.7 years.
Main Results:
- No component revision for aseptic loosening; 100% cumulative survival at latest follow-up.
- One polyethylene liner revision for wear; one failure due to infection.
- Radiographic loosening observed in 8% of cases.
Conclusions:
- The stemmed acetabular component demonstrates excellent survivorship for severe acetabular deficiency.
- It is a reliable option for complex primary and revision total hip arthroplasty.
- Justifies continued use in challenging acetabular reconstructions.
Abstract:
We evaluated the use of a stemmed acetabular component in the treatment of severe acetabular deficiency during revision and complex primary total hip arthroplasty. There were 31 hips of which 24 were revisions (20 for aseptic loosening, four for infection) and the remainder were complex primary arthroplasties. At a mean follow-up of 10.7 years (6 to 12.8), no component had been revised for aseptic loosening; one patient had undergone a revision of the polyethylene liner for wear. There was one failure because of infection. At the latest follow-up, the cumulative survival rate for aseptic loosening, with revision being the end-point, was 100%; for radiographic loosening it was 92% and for infection and radiographic loosening it was 88%. These results justify the continued use of this stemmed component for the reconstruction of severe acetabular deficiency.
