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 …
