Abstract

The present invention relates to an osteosynthesis plate (1;1'; 101) for femur fractures, more particularly for fractures in the epiphysis or head of said femur. The osteosynthesis plate according to invention allows to take into account the antiversion angle of the fractured femur, so as to guarantee a correct insertion and a correct positioning of the bone head supporting means (9;95) - comprising for instance a bone head screw or a bone head nail - in the femur head. According to the invention, the axis (A;A') of the bone head supporting means (9;9') does not lie in the plane passing through the longitudinal axis of the body of the osteosynthesis plate (1; 1'; 101) and perpendicular to the plane (P) wherein said body lies, but it is adequately inclined at an angle with respect to said plane, said angle (β;β';ƴ) being preferably comprised between 1° and 30°, and more preferably comprised between 1° and 15°.
