title: [Bilateral femoral fracture at the site of bilateral hip prostheses. A case report].
abstract: Fracture of the femoral shaft after hip arthroplasty is a serious problem. In most cases, minimal trauma is responsible for the fracture. Predisposing factors include severe osteoporosis, loosening of the prosthetic stem and perforations of the cortex. The incidence in our patient material in 2.3% after total hip arthroplasty and 2.9% after revision. Operative treatment may consist in osteosynthesis with compression plates, screws, or cerclage wires with or without revision of the arthroplasty. We give a case report covering treatment and 2-year follow-up for a bilateral proximal femoral fracture in a 72-year-old farmer with bilateral total hip replacements. Both fractures were treated similarly, with replacement of the femoral components by a cementless Wagner revision stem prosthesis and cerclage wiring of the fragments. No classic osteosynthesis was required to manage the fractures.
