Implant system for bone fixation

摘要

An implant system for fixation of bone includes an intramedullary nail, an extramedullary plate, and a bone fastener. The intramedullary nail has a connecting opening defining a first axis and a transverse opening defining a second axis and is configured to receive the bone fastener. The bone fastener is configured to penetrate a first through opening of the extramedullary plate and the transverse opening of the intramedullary nail. The implant system comprises a connecting fastener to fasten the extramedullary plate to the intramedullary nail by insertion through the second through opening of the extramedullary plate and the connecting opening of the intramedullary nail. The first axis is oblique with respect to a longitudinal axis of the intramedullary nail and parallel to the second axis of the transverse opening. Thus, the extramedullary plate can move parallel to the longitudinal axis of the bone fastener towards the intramedullary nail.

1. An implant system for use in orthopaedic surgery for fixation of bone, comprising:
an intramedullary nail with a connecting opening defining a first axis and a transverse opening defining a second axis and configured to receive a bone fastener; an extramedullary plate having a first through opening and a second through opening;a bone fastener configured to penetrate the first through opening of the extramedullary plate and the transverse opening of the intramedullary nail;
a connecting fastener configured to fasten the extramedullary plate to the intramedullary nail, the connecting fastener being adapted to be inserted through the second through opening of the extramedullary plate and the connecting opening of the intramedullary nail, wherein the first axis of the connecting opening of the intramedullary nail is oblique with respect to a longitudinal axis of the intramedullary nail and is substantially parallel to the second axis of the transverse opening of the intramedullary nail; andwherein the extramedullary plate comprises at least one guiding structure configured to be received by the transverse opening of the intramedullary nail.
