In this study, mechanical properties of the femur with fixation using the Gamma nail and the compression hip screw, which is widely used as the fixation devices of trochanteric fracture, is investigated by three-dimensional finite element method. The results obtained are as follows. (1) On the medial and lateral surface of the intact femur, the stress distribution increases around the lower of trochanter. (2) The rigidity of the implanted femur increases, when the fixation is inserted in the fracture division, though the surface stress at the proximal part considerably decreases. (3) In the CHS fixation, the surface stress of the femur covered by the plate remarkably decreased. (4) The stress around the fourth screw rapidly increases, when double ends of the CHS plate contact the femur. (5) The CHS method is not suitable for the unstable fracture, because the stress of fracture division of the lesser trochanter considerably increases. (6) Mechanical properties of the implanted femur with Gamma nail are more similar to the intact femur than the implanted femur with CHS.
