Comparison of Locked Plates and Blade Plates for Varus Osteotomy of the Proximal Femur by the Finite Element Method.

 The present study compared the difference in load and pressure distribution behavior of the blade plate and locked plate for varus osteotomy of the proximal femur per the finite element method.  Modeling was performed by scanning a medium-sized left femur with medial valgus deformity made of polyurethane.  The stiffness of the locked plate is higher compared with that of the blade plate.
