Angularly stable fixation of an implant

摘要

A system and method of angularly stable fixation of an implant on a bone includes the steps of making at least one hole in the bone by means of a bone drill. An implant is placed on the bone in a desired position and joining the implant with the bone, such that the implant is prevented from rotation about its attachment point. A system is provided for use in the above described method. The system comprises a bone drill, an implant and a sonotrode for angularly stable fixation of the implant on the bone. The system can further comprise a joining element to join the implant with the bone.

1. A system for angularly stable fixation of an implant to a bone, wherein the system comprises
a tool for preparing a hole in the bone, a sonotrode, an implant with a top surface and a vertical axis normal to the top surface, and a jig including a first channel extending along a first axis arranged at an angle to the vertical axis, and a second channel extending along a second axis arranged parallel to the vertical axis, wherein the tool can be advanced through the first channel to prepare the hole in a desired position in the bone, the angle of the first channel locating the hole in the bone below an open end of the second channel and wherein the sonotrode can be accepted and guided in the second channel along the second axis, and wherein the implant comprises a material which is fluidizable by the sonotrode, so that at least a portion of the implant can be melted and the melted material can be pushed into the hole in the bone to fix the implant in an angularly stable manner in the bone when the melted material solidifies again.
