METHOD OF FASTENING A TISSUE OR A CORRESPONDING PROSTHETIC ELEMENT IN AN OPENING PROVIDED IN A HUMAN OR ANIMAL BONE AND FASTENER SUITABLE FOR THE METHOD

摘要

For example, an implant 1 or a prosthetic element suitable for replacing a tendon or ligament is fastened in a bone tunnel or blind hole with the aid of a fastener 3. [ In the first step, the graft 1 or the prosthetic element is pressed into the tunnel or hole by pressing the fastener 3 into the hole or by positioning the fastener in the hole and then expanding it, Is in contact with the graft 1 or prosthetic element and with the bone wall of the tunnel or blind hole. In a second step, with the aid of a liquefiable material where the liquefiable material liquefied near the bony wall is in contact with the fastener, and by allowing the liquefied material to penetrate into the bore wall, the fastener 3 is inserted into the tunnel or blind hole And is fixed within the bone wall. For the second step, the fixing element 6 comprising the liquefiable material is advanced relative to the fastener 3 and energy, preferably vibration energy, is applied to the fixing element 6 or to the fastener 3 at the same time . The fastener surface provided for fixation is provided with an inlet for the passage which connects the fastener surface to the inner fastener cavity 4 in which the liquefiable material is liquefied therein or a groove extending from the proximal fastener surface to the distal fastener end .
