摘要:
A graft or prosthetic element is fastened in a bone tunnel or blind openingusing afastener. The element is press-fitted in the tunnel or opening by forcing thefastener intothe opening or positioning the fastener in the opening and expanding it, suchthat thefastener is in contact with the element and with the bone wall of the tunnelor blindopening. The fastener is anchored in the bone wall using a liquefiablematerial and bymaking the liquefied material penetrate into the bone wall. An anchoringelementcomprising the liquefiable material is advanced relative to the fastener andvibrationalenergy is transmitted to the anchoring element or fastener. Fastener surfacesequipped forthe anchoring comprise mouths of passages connecting the fastener surface withan innerfastener cavity, in which the liquefiable material is liquefied, or groovesextending front aproximal fastener face towards a distal fastener end.
