Type A fractures are located at the proximal end of the prosthesis, with a greater or lesser rotor fracture. Type B fractures occur around or just below the stem of the prosthesis Type B1 prosthesis is firmly fixed with no significant bone loss; Type B2 prosthesis is loose but without significant bone loss; Type B3 prosthesis is loose and has significant bone loss Type C fractures occur at a distance from the tip of the prosthesis. If the fracture is caused by severe osteolysis, revision surgery should be performed, and if necessary, the acetabular prosthesis can be revised at the same time. B1 has more non-operative complications, and the incidence of loosening, fracture non-union and deformity healing is higher, and is treated by incision and internal fixation, mostly using titanium cables or screws, allograft bone plates and plates. Types B2 and B3 require replacement of the prosthesis. Type C fractures require incision and internal fixation. If the prosthesis is loose, the fracture can be treated with incision and internal fixation first, and then revision surgery can be performed after the fracture has healed.
