The fixation of distal femoral fractures (Vancouver type-C fractures) following a well-fixed hip arthroplasty femoral stem has become a challenging issue for orthopedic surgeons due to the inter-prosthetic biomechanical effects such as negative, positive, and torsional strain. Surgeons have applied a range of constructs to overcome these difficulties. To minimize the risk of inter-prosthetic fr...

The aim of this study was to perform a biomechanical analysis of the cement-in-cement (c-in-c) technique for fixation of selected Vancouver Type B1 femoral periprosthetic fractures and to assess the degree of cement interposition at the fracture site. Six embalmed cadaveric femora were implanted with a cemented femoral stem. Vancouver Type B1 fractures were created by applying a combined axial ...

BACKGROUND AND PURPOSE Historically, the treatment of periprosthetic femoral fractures (PFFs) has been associated with a high frequency of complications and reoperations. The preferred treatment is internal fixation, a revision of the femoral stem, or a combination of both. An improved understanding of plate use during internal fixation, and the introduction of locking-plate osteosynthesis may ...

Periprosthetic fracture of the femur is an uncommon complication after total hip replacement, but appears to be increasing. We undertook a nationwide observational study to determine the risk factors for failure after treatment of these fractures, examining patient- and implant-related factors, the classification of the fractures and the outcome. Between 1979 and 2000, 1049 periprosthetic fract...

Periprosthetic fractures of the femur present a challenging surgical problem. The aim of this study was to evaluate the outcome of periprosthetic femoral fractures (PFF) which were treated with internal fixation or stem revision. Depending on the fracture type in the Duncan-Vancouver-Classification, 42 patients with PFF were treated either with a Fixateur interne (n = 23) in cases with type B1 ...

INTRODUCTION Periprosthetic femur fractures, defined as femur fractures occurring around a pre-existing prosthetic hip or knee, are increasing in incidence on par with the number of arthroplasties performed in our increasingly aging population. Periprosthetic hip fractures most commonly occur around or just distal to a hip stem prosthesis (Vancouver Type B, 88%) [1], and periprosthetic distal f...

The use of allograft struts and cerclage wire, possibly augmented by plate fixation, for the treatment of Vancouver type-B1 peri-prosthetic fractures around a total hip replacement has been strongly advocated. We examined our results using plate fixation without allograft struts and compared them with the results of the use of struts alone or when combined with plate fixation. Of 20 consecutive...

BACKGROUND We analyzed the radiological and clinical results of our study subjects according to the management algorithm of the Vancouver classification system for the treatment of periprosthetic femoral fractures in hip arthroplasty. METHODS We retrospectively reviewed 18 hips with postoperative periprosthetic femoral fractures. The average follow-up was 49 months. The fracture type was dete...
