ABSTRACT
[Objective]To introduce the technology of bone grafting with acetabular reinforcement device for the massive bone defects in the revision total hip arthroplasty.[Method]The massive acetabular bone defects were reconstructed in 8 cases from 2002 and 2007.The defects were classified according to the system of D'Antonio,ⅡB defects in 1 case,ⅡC defects in 2 cases,and Ⅲ defects in 5 cases.Methods:the reinforcement device with the morsellised impaction bone grafting in 3 cases,the reinforcement device with the morsellised impaction bone grafting and the structural autograft in 5 cases.Clinical and radiological evaluations were conducted for each patient.[Result]The follow-up duration averaged to 2.7 years,the Harris score were inoreased by 35 points in average.No hip required further revision of the acetabular component because of aseptic loosening.[Conclusion]The cavitary bone loss could be reconstructed by the bone-impaction grafting;the segmental bone loss could be reconstructed by the structural autograft.The acetabular reinforcement device can fix the grafted bone and support the cup.The massive periacetabular bone loss could be effectively reconstructed by reinforcement device with bone grafting.
