Type of fracture is located at the proximal end of the prosthesis, with a greater or lesser trochanteric fracture. Type 1 fracture occurs around or just below the stem of the prosthesis; Type 2 fracture is firmly fixed without significant bone loss; Type 3 fracture is loose but without significant bone loss; Type 4 fracture is loose and has significant bone loss. Type 1 fractures occur farther from the tip of the prosthesis. If the fracture is due to severe osteolysis, revision surgery should be performed, and if necessary, the acetabular prosthesis can be revised at the same time. Non-operative complications are more frequent, and the incidence of loosening, fracture non-union and deformity healing is higher, which is mostly treated by incision and internal fixation, mostly using titanium cables or screws, allograft bone plates and plates. With B3 type requires replacement of the prosthesis. If the prosthesis is loose, the fracture can be treated by incision and internal fixation and then revision after the fracture has healed.
