An endomedullary nail for the treatment of proximal femur fractures, comprising an elongate body (12) having a proximal portion (14) and a distal portion (16). The proximal portion (14) has a first and a second hole (20, 21) for a respective cephalic screw (22, 23, 24, 25), each having a transversal axis to the axis of the proximal portion (14). The first hole (20) is split into two passages each having a respective axis (A, B) with a predetermined angle relationship with respect to the axis (C) of the second hole (21). The passages (30, 31) are arranged to be selectively engaged by a respective cephalic screw (22, 24). |
