Failure of bulk bone grafts after total hip arthroplasty for hip dysplasia.

摘要

Results of this study show significant decrease in acetabular cup stability when either autograft or allograft is used for cemented acetabular reconstruction of dysplastic hip. Further, allografts showed twice as rapid failure as autografts. Although these results contradict both good short-term and long-term results in published literature, they present warning for future use of free bulk bone grafts in reconstructive hip surgery.
