An targeting device for intertrochanteric fracture includes a handle portion and an insertion portion to define an included angle; a protruding portion being formed at a free end of the insertion portion; a through hole being provided on the insertion portion at where closer to its center; the insertion portion being placed into a neck of the femur at where closer to its center; a guide wire being inserted via the through hole for the targeting device to fast and accurately achieve the central fixation at a head of the femur thus to match the femur and the neck of the femur for facilitating subsequent processes of drilling and placement of a dynamic hip screw to firmly secure the femur where the fracture takes place.
