Abstract
An anchoring rod includes a proximal zone and an axial anchoring zone having a plurality of sides arranged in a generally square cross-section and joining at least two pairs of cutting fins. Each pair of cutting fins includes two fins spaced by a recess having opposed sides. Each fin formed by a dihedron provided by the intersection of the adjacent sides of the anchoring zone and recess. The two most remote sides of the dihedra of the pair of fins form an angle of from 60.degree. to 120.degree.. This angular relationship is applicable to the extents of the remote sides extending a distance only in the order of one millimeter from the adjacent fin, the length being measured from each fin along the surfaces of the respective sides.
