UPDATE ON INTERNAL-FIXATION OF SUBTROCHAN TERIC FEMUR FRACTURES

Operative treatment of subtrochanteric femur fractures is demanding. T he implants available follow different biomechanical and surgical prin ciples. Extramedullary implants like the condylar blade plate and the dynamic condylar screw require subtle surgical and indirect reduction techniques. Intramedullary implants like intramedullary hip screws and interlocking nails are biomechanically advantageous. In contrast to t he extramedullary implants these fixations can stand postoperative wei ght-bearing. The different operative techniques for the fixation of su btrochanteric fractures are presented and evaluated. Current trends in treatment rationales are outlined.
