Periprosthetic Fractures Of The Femur After Total Hip Arthroplasty And Hemiarthroplasty: A Review, Reilly R. Kuehn
Periprosthetic Fractures Of The Femur After Total Hip Arthroplasty And Hemiarthroplasty: A Review, Reilly R. Kuehn
UNM Orthopaedic Research Journal
Periprosthetic fractures of the femur after total hip arthroplasty (THA) and hemiarthroplasty represent relatively uncommon but challenging complications. The incidence of these types of fractures has been rising, owing to an increasing number of hip arthroplasties performed, aging population, and prevalent use of uncemented stems, which may have unsuccessful long-term results compared with use of cemented stems. Method of treatment has been generally based on the Vancouver classification system that describes radiographic characteristics of fractures and stability of the femoral stems in respect to placement in the bone. In particular, the presence of loose stems has often indicated the need …

Background: Periprosthetic fractures of the femur after primary total hip arthroplasty (THA) can be complex and difficult injuries to treat. Because of the increased prevalence of THA, an overall increase is anticipated in the incidence of this complication. Vancouver types B1 and B2 periprosthetic femur fractures (defined as fractures around or just below the stem, with well-fixed and loose femoral stems, respectively) are particularly challenging to accurately classify and thereby treat owing to the difficulty in interpreting stability of stems on initial radiographs. To determine whether the method of stem fixation (ie, cement or press fit) may be a predictor …
