Bone anchoring base and set of elements including said base

摘要

The plate has an anchoring unit comprising wall portions (12) separated from each other and located near a peripheral wall of a base edge. The base edge is connected to a base wall (10), where a free end edge of the base wall is positioned opposite to a bottom edge. Two side edges of the base wall are extended between the base edge and the free end edge. The portions are arranged on the base wall such that one of the side edges is located at a distance from center of the base wall, which is different from another distance of the other side edge with respect to the center. An independent claim is also included for an elements assembly for creating a joint prosthesis.
