The biomechanical assessment of fixation methods in periprosthetic femur fractures

The aim of our study was to compare the biomechanical properties of different fixation methods used in periprosthetic femur fractures. We created sawbone models with Mallory Type 2 periprosthetic femur fractures. The periprosthetic fractures were fixed with cables, cables and strut graft, or cables and plates. The biomechanical properties of these three different fixation methods were compared with the intact femur, the intact femur with prosthesis and the femur with periprosthetic fracture without fixation. The periprosthetic fracture without fixation had a significantly lower yield point value than the periprosthetic fractures with fixation (p
