Investigation of the Revison Arthroplasty After Bipolar End Prosthesis

We have investigated case of bipolar end prosthesis after which the patients required revision arthroplasty.There have been 7 osteoarthritis (OA) patients and 4 rheumatoid arthritis (RA) patients and one infection patient after femoral neck fracture. The most important problem is migration, especially in case of acetabular dysplasia.Both the timing of partial weight bearing and revision arthroplasty are very difficult.
