Fig 2. Tensile test.

A homemade device is used to measure the adhesion load between the implant and the bone. Briefly, tibial bone is placed, implant downwards, on a flat metal bracket containing a hole allowing the implant to be loaded by a tension device. Highly resistant wire is passed through the implant hole then connected to the load system. The mobile part of the testing device is slowly displaced to stretch the wire until the implant loosened. Graphic in lower part indicates the time-curve of force recorded and the maximum load value obtained just before the breakout of the implant marked by a thin arrow.
