Abstract: Aiming device for an implant to attend trochanter and subtrochanter fractures, comprising a head for connecting a famur pin and with an aiming arm (10) mounted laterally on the head which extends approximately -arallel to the femur pin and at least two slanted aiming passages (12, 13) aligned to proximal slanted passages of the femur pin for a shank neck blade or the like, and at least two transverse aiming bores aligned to distal transverse bores of the femur pin for accommodating a strike-in sleeve and/or bore sleeve. The slanted aiming passages (12, 13) include different angles relative to the aiming arm axis (11). The longitudinal axes of the slanted aiming passages (12, 13) further cross the longitudinal axes of the transverse aiming bores (21, 22). The aiming arm (10) and head for connection of the femur pin are detachable joined together.
