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 …

Comparison Of Blood Loss Between Short-Stem And Conventional Femoral Implants In Total Hip Arthroplasty, Sean Kuehn, Drew K. Newhoff, Dukens Labaze, Aditi S. Majumdar, Rick J. Gehlert

UNM Orthopaedic Research Journal

Background: Although the postoperative results of total hip arthroplasty (THA) are generally successful, the standard technique and implant design have many proposed modifications. The purpose of the current study was to determine if using short-stem femoral implants minimized the intraoperative blood loss during THA when compared with conventional THA.

Methods: The medical records of patients who underwent THA using short-stem and conventional femoral implants between 2009 and 2013 were reviewed. Patients with previous surgical procedures for treating the acetabulum or proximal femur and patients without reported hematocrit levels were excluded; subsequently, a total of 53 patients for each group (short-stem …
