Endomedullary nail for the treatment of proximal femur fractures

An endomedullary nail for the treatment of proximal femur fractures, comprising:

• an elongate body having a proximal portion and a distal portion, the proximal portion having a first and a second hole for a respective cephalic screw;
• said first hole having a eight-shaped cross section defined by two passages;
• each of said two passages having a respective axis with a predetermined angle relationship with respect to the axis of the second hole;
• said passages being arranged to be alternately engaged by a respective cephalic screw.

An endomedullary nail for the treatment of femur fractures, comprising:

• an elongate body having a proximal portion and a distal portion;
• an “eight-shaped” slot formed in said proximal portion by two interfering passages for receiving corresponding fixing screws in each passage;
• a hole in said proximal portion;
• each of said passages having a respective axis with a predetermined angle relationship with respect to the axis of the nail and to the axis of said hole in said proximal portion.

A device for the treatment of proximal femur fractures comprising:

• an endomedullary nail having a proximal portion and a distal portion, the proximal portion having a first and a second hole each having a transversal axis to the axis of the proximal portion, and
• cephalic screws suitable for insertion into said first and a second hole of the endomedullary nail, respectively;
• the first hole of the nail having a eight-shaped cross section defined by two cylindrical passages which are adjacent and longitudinally open the one into the other;
• each of said passages having a respective axis with a predetermined angle relationship with respect to the axis of the second hole, said passages being arranged to be alternately engaged by one of the cephalic screws, and wherein
• two first cephalic screws being suitable for insertion in the second passage of the first hole and in the second hole, respectively, to obtain a first configuration;
• and
• two second screws being suitable for insertion in the first passage of the first hole and in the second hole, respectively, to obtain a second configuration alternative to the first configuration.
