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.

Polyaxial locking hole arrangement

A method for implanting a longitudinal intramedullary nail into the tibia comprises inserting the tibia nail along a plane of symmetry through the tuberositas tibiae. Thereby, the tuberositas tibiae can be used during nail insertion to correctly align the nail and the target arm to the symmetry plane of the bone. This means, that the whole construct, the nail attached to the target arm, has to be inserted in external rotation.

Method for tibial nail insertion

An intramedullary nail has a driving end portion and a non-driving end portion with a longitudinal axis. The non-driving end portion comprises a locking hole arrangement with a sequence of four holes, i.e. spaced from non-driving to driving end a first hole, a second hole, a third hole, and a fourth hole. The first hole and the fourth hole have a corresponding first orientation and the second hole and the third hole have a corresponding second orientation.
