    摘要: A surgical joint implant has a cap in the form of at least two intersecting circles of the same diameter having an articular outer surface and an inner surface for bone adhesion. At the center of each circle a peg, for bone insertion into a hole of a nominal diameter, extends. One peg is slightly larger than said nominal diameter, to achieve an interference fit and the other peg is slightly thinner, to achieve a slide fit. A tubular drill rig open at both ends and having an interior circumference corresponding to the outer shape of the implant, can be mounted over the bone surface to be repaired. It accommodates a double drill for drilling, at the same time, a shallow hole of the diameter of the intersecting circle and a deeper narrow hole at the center of the circle of said nominal diameter.
