<p>A nail for reducing fractures of the trochanter and of the neck of the femur, comprising an elongated and angled shank (2) in which, proximate to the upper end, a head screw (5) can be inserted downward from above and can be locked to the nail by a screw (8) which is screwed into a threaded axial hole (9) of the top of the shank (2); the shank has, in order to facilitate insertion in the medullary canal and reduce and better distribute the mechanical stresses affecting the bone, a lower end (3) which is cut along an inclined plane like a flute mouthpiece and has, proximate to a hole (4) for the insertion of the head screw (5), a through hole (11) which has a reduced diameter and is substantially parallel to the hole of the head screw (5), for the passage of a wire (12) which is threaded at its top end (13) for temporary screwing in the head of the femur (F) and is adapted to avoid rotations of the head of the femur during the screwing of the head screw (5). <IMAGE></p> |
