Abstract
-
PURPOSE: We evaluated the results of secondary total hip arthroplasty (THA) after acetabular fracture.
MATERIAL & METHODS: Twenty cases of THA were performed to treat acetabular fracture as a secondary treatment after conservative management (6 cases) or internal fixation (14 cases). The mean follow up period was 5 years 2 months. The cause of secondary THA was post traumatic arthritis in 15 hips and osteonecrosis of the femoral head in 5. Cementless acetabular cup was used in 18 cases and cemented in 2 cases. Cementless femoral component was used in 18 cases and cemented in 2 cases. Serial Harris hip score (HHS), pain, limb length discrepancy and radiographs were evaluated.
RESULTS
HHS improved from 57 points to 91 points. Osteolysis in the acetabular component occurred in 2 cases and 5 cases in the femoral component. Loosening occurred in 2 cases of cemented acetabular components and 1 case in the femoral component. In this study, 3 cases (15%) required revision of the acetabular component and 2 cases (10%) of the femoral component.
CONCLUSION
The clinical results of THA after acetabular fracture was inferior to that of conventional arthroplasty. The secure cementless acetabular fixation with proper bone grafting is mandatory to improve the survival of acetabular component.
