Abstract
We report a case of periprosthetic fracture of the femur after total hip arthroplasty (THA). The patient was a 77-year-old woman who had undergone THA at the age of 50 for osteoarthritis of the hip. Six years ago, implant loosening had been pointed out. Pain appeared when the hip was twisted three days ago, and walking became difficult. Radiograph showed an oblique periprosthetic fracture of the femur and bone defects of the proximal femur. The diagnosis was Vancouver classification type B3. Open reduction internal fixation with a LCP reconstruction plate 4.5/5.0 and revision THA with a cemented long stem were performed. At the end of the follow-up period of seven months, no implant failure had occurred. LCP, periprosthetic screws and a cable system were useful for fixation of the periprosthetic fracture. However, it may be difficult to obtain a good long-term result when stem revision for Vancouver type B3 is performed with only bone cement.
