  • Publication number: 20240148417
    Abstract: A femoral nail includes a proximal portion configured to engage a driving tool for driving the femoral nail into a femur, a distal portion remote from the proximal portion, and an intermediate portion extending from and between the proximal portion and distal portion. The intermediate portion has a circular screw hole and an elongated screw hole extending therethrough. The circular screw hole having a central axis, and the elongated screw hole having a first axis and a second axis that are separated by a distance. The central axis of the circular screw hole is located a distance from a proximal end of the femoral nail that is 61-64% of a total length of the femoral nail, and the first axis of the elongated screw hole is located a distance from the proximal end of the femoral nail that is 70-73% of the total length of the femoral nail.

  • Patent number: 8337505
    Abstract: A method of connecting an intramedullary nail and a targeting and/or nailing instrument includes engaging a coupling element which has an axially parallel projection with an axially parallel recess on the hollow connection end of the nail. The engagement of the projection and recess fastens the nail under axial engagement on the connection end of the instrument in predefined rotational position on the instrument. A quick-fastener element engages in the connection end of the nail and has a first coupling element and the connection end of the nail has a second coupling element. The coupling elements are configured so that in a first rotational position relative to the axially parallel projection the instrument can be introduced into the connection end of the nail and in a second rotational position the coupling elements cooperate so that the nail is held axially fixedly on the instrument.

  • Patent number: 7901410
    Abstract: An intramedullary nail and a targeting and/or nailing instrument includes a connector end which has an axially parallel projection which cooperates with an axially parallel recess on the hollow connection end of the nail. The engagement of the projection and recess fastens the nail under axial engagement on the connection end of the instrument in predefined rotational position on the instrument. A quick-fastener element engages in the connection end of the nail and has a first coupling element and the connection end of the nail has a second coupling element. The coupling elements are configured so that in a first rotational position relative to the axially parallel projection the instrument can be introduced into the connection end of the nail and in a second rotational position the coupling elements cooperate so that the nail is held axially fixedly on the instrument.

The engagement of the projection and recess fastens the nail under axial engagement on the connection end of the targeting and nailing instrument in predefined rotational position on the targeting and/or nailing instrument. A guide fastener element is rotationally mounted on the connection end of the targeting and/or nailing instrument.
