The device null proximal side part for remedying the femoral proximal section fracture which uses the medullary nail

摘要

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).
