ABSTRACT:
Fastening means for artificial joints including two titanium wires that are wound into a spiral and wherein the wires clamp a number of bristles between them that extend essentially radially outwards toward the interior of the bone. The bristles are a little bit too long for undisturbed insertion into the cavity of the bone and, thus they will be slightly turned backwards on insertion, thereby securing a very steady grip once inserted.
