Clinical trials

Total hip arthroplasty (THA) yields excellent results. To perform the procedure, the surgeon must make certain decisions, including the choice of fixation method for the femoral implant. This surgery, considered to carry a risk of bleeding, therefore exposes the patient : * to complications: heart attacks, strokes... * to mortality * to transfusion: specific risks, cost, length of hospital stay * to anemia: fatigue, longer recovery time The influence of the femoral fixation method on bleeding and blood loss is often debated, but the literature on the subject is very limited. Our hypothesis is that the method of femoral fixation in THA influences bleeding and blood loss, with a benefit for cemented fixations.
