Abstract
Fixing device comprising (I) a surgical cable (16) having a first and a second end and (II) at least a first (2) and a second (4) fixing plate having a first (6) resp. second (8) central hole and a first (10) resp. second (12) ring surrounding said first resp. second hole, the circumference (20) of each fixing plate forming an outer edge of its ring and an inner edge of its ring being adjacent to the hole it surrounds, the first fixing plate being in a stacked position on top of the second plate leaving a gap (26) between the plates and the holes at least partly overlapping each other, wherein in the ring of one of the fixing plates in its surface facing the other fixing plate a continuous groove (50) is present running between the outer edge and the inner edge of said ring and in the ring of the other fixing plate, in its surface facing the one of the fixing plates a ridge (52) is present matching with said groove, and wherein the cable ends follow a continuous trajectory running around and between the plates and through the holes in such way that by drawing the cable ends the cable is tensioned around the bone parts and fixate these.
