As a mature technology gradually, the total hip arthroplasty has been known and conducted by more and more orthopedic surgeons. However, it also increased the number of hip revisions. The reasons for revision of hip mainly include: unstable, infection, aseptic loosening prosthesis, prosthesis peripheral fracture, liner wear and so on, and the acetabulum bone defect and the choice of acetabular prosthesis have been perplexing surgeons. In this paper, we summarise classification and reconstruction of acetabulum bone defect in hip revision oprations, compare the advantages and disadvantages of all kinds of classification, on this basis can have more than one bone grafting mode and the choice of the acetabulum prosthesis for reconstruction of acetabulum, then expound the ways of material sources, bone grafting modes and complex acetabulum bone defect reconstruction as well as the choice of the ways of fixed prosthesis, providing the basis for clinical doctors to deal with all kinds of acetabulum bone defect and the choice of the acetabulum prosthesis, guiding patient specific therapy more precisely.
