Abstract
An intramedullary nail according to the invention has a locking hole arrangement having one first opening on one side of the intramedullary nail and one second opening at an opposing side of the intramedullary nail. The locking hole arrangement has a first bore having a first bore axis and a second bore having a second bore axis. The first bore and the second bore each having a first orifice on one side of the intramedullary nail and each having a second orifice at an opposite side of the intramedullary nail. The first bore axis and the second bore axis are inclined with respect to each other and the first bore and the second bore intersect each other within the intramedullary nail.

An intramedullary nail, comprising:
- a locking hole arrangement having a first opening on one side of the intramedullary nail and a second opening at an opposing side of the intramedullary nail,
- wherein the locking hole arrangement comprises a first bore having a first bore axis, and a second bore having a second bore axis,
- wherein the first bore and the second bore each having a first orifice on one side of the intramedullary nail and each having a second orifice at an opposing side of the intramedullary nail,
- wherein the first bore axis and the second bore axis are inclined with respect to each other,
- wherein the first bore and the second bore intersect each other,
- wherein the first orifice of the first bore and the first orifice of the second bore together form the first opening of the locking hole arrangement,
- wherein the second orifice of the first bore and the second orifice of the second bore together form the second opening of the locking hole arrangement.
An intramedullary nail, comprising:
- a locking hole arrangement having a first opening on one side of the intramedullary nail and a second opening at an opposing side of the intramedullary nail,
- wherein the locking hole arrangement comprises a first bore having a first bore axis, a second bore having a second bore axis, and a third bore having a third bore axis,
- wherein the first bore, the second bore and the third bore each having a first orifice on one side of the intramedullary nail and each having a second orifice at an opposing side of the intramedullary nail,
- wherein the first bore axis, the second bore axis and the third bore axis are inclined with respect to each other,
- wherein the first bore, the second bore and the third bore intersect each other,
- wherein the first orifice of the first bore, the first orifice of the second bore, and the first orifice of the third bore together form the first opening of the locking hole arrangement,
- wherein the second orifice of the first bore, the second orifice of the second bore and the second orifice of the third bore together form the second opening of the locking hole arrangement.
An intramedullary nail, comprising:
- a body having a first body portion extending along a longitudinal axis;
- a locking hole arrangement in the first body portion having a first opening on one side of the intramedullary nail and a second opening at an opposing side of the intramedullary nail;
- wherein the locking hole arrangement comprises a first bore having a first bore axis, a second bore having a second bore axis, and a third bore having a third bore axis, the first, second and third bore axis lying in a plane extending transverse to the longitudinal axis;
- wherein the first bore, the second bore and the third bore each having a first orifice on one side of the intramedullary nail and each having a second orifice at an opposing side of the intramedullary nail;
- wherein the first bore axis, the second bore axis and the third bore axis are angled with respect to each other in the plane and intersect within the nail body first portion;
- wherein the first orifice of the first bore, the first orifice of the second bore, and the first orifice of the third bore together form the first opening of the locking hole arrangement;
- and
- wherein the second orifice of the first bore, the second orifice of the second bore and the second orifice of the third bore together form the second opening of the locking hole arrangement.
