ABSTRACT:
A set is provided for creating an offset-resurfacing hip-joint implant. The set includes a 1 to 1.5 mm thick metallic acetabulum shell (1) for insertion into the natural acetabulum, from which only cartilage has been removed, a metallic head cap (2) for placement on the natural hip-joint head, from which only cartilage has been removed, and an inlay (3) for insertion into the acetabulum shell (1) as a sliding partner for the head cap (2). The inlay has a material thickness of 2 to 5 mm. The head cap (2) has a wall thickness which increases constantly from a thickness of 2 mm to 6 mm viewed in cross section in the region of the base edge (6) of the head cap, so that an eccentricity is produced in its outer shape.
