Purpose: To evaluate the radiographic mid-to long-term result of femoral revision hip arthroplasty using impacted cancellous allograft combined with cemented, collarless, polished and tapered stem.
Materials and methods: Among 27 patients with impacted cancellous allograft with a cemented stem, 28 hips from 26 consecutive patients were analyzed retrospectively. The average patient age was 59 years. The follow-up period ranged 36 months to 10 years, 3 months (mean, 76.6 months). Radiographic parameters analyzed in this study included subsidence of the stem in the cement, subsidence of the cement mantle in the femur, bone remodeling of the femur, radiolucent line, and osteolysis.
Results: Radiographic analysis showed very stable stem initially. 27 stems showed minimal subsidence (less than 5 mm) and 1 stem showed moderate subsidence (about 8 mm) in the cement. But there was no mechanical failure and subsidence at the composit-femur interface. Evidence of cortical and trabecular remodeling were observed in all cases. No radiolucent line or osteolysis were found in the follow-up period. There were 4 proximal femoral cracks and 1 distal femoral splitting during operation.
Conclusion: The result of cemented stem revision with the use of impacted cancellous allograft was good mid-to long-term. and femoral bone stock deficiency may be reconstructed successfully.
