摘要

In revision total hip arthroplasty, beside difficult exposure and components removal, the surgeon may experiencevariable bone defects in femoral and acetabular sides. Managing the deficiencies of each bone has different options.One of them is the use of structural bone graft. All hip arthroplasty or total hip arthroplasty after acetabular fracturesor periprosthetic fractures need structural allograft during 2005-2014 were included in this study. According to theresults, average follow up period was 5.5 years (1to 9 years). Twenty nine patients met the criteria to be enrolled.Three cases of total hip arthroplasty after acetabular fracture, 2 cases of periprosthetic fracture (B3), 5 cases withconversion of hemiarthroplasty to total hip arthroplasty, 2 cases with conversion of fused hip to total hip arthroplasty,1 case with conversion of girdle stone to total hip arthroplasty and 16 patients candidates of revision due to looseningand osteolysis formed our study population. Osteolysis is the main cause of allograft usage. Post-operative scoresraised dramatically. These results suggest application of structural allograft is a useful way to manage massive bonedefect in acetabular and also in femoral side and it prepares excellent primary support for stem and cup.
