Abstract
When performing total hip arthroplasty (THA) for a rheumatoid arthritis patient with protrusio acetabuli, we made an acetabular model by computerized reconstruction of CT scan data. Using this model, a graft of dense hydroxyapatite plus tricalcium phosphate was made to fit the defect in the acetabular roof. Surgery was relatively easy and the graft fitted well. This method appears useful for THA when there is a large acetabular roof defect.
