| abstract |
A prosthesis suitable for small joints which may be implanted without cement has two parts (12, 14) composed each of a joint element (20, 22) made of PE and of a titanium cast anchoring unit (16, 18). The anchoring units (16, 18) have each a bearing plate (28) and at least one anchoring element (38) supported on the bearing plate and constituted by a nucleus (40) and anchoring disks (42) supported thereon. At least one end section of the anchoring elements (38) is elastically and/or plastically deformable, so that the anchoring elements may fit into the contour of a recess created in a bone. |
