Claim:
A monolithic humeral head resurfacing implant comprising: a head having: an exterior hemispherical articulating surface defining a terminating rim; an interior concave surface opposite said exterior articulating surface; an anchoring stem coupled to the interior concave surface and extending along an axis that extends through an axial center of the head; and an extended articulating surface member defining a flange axially protruding from only a portion of said terminating rim, said extended articulating surface member operable to articulate with at least one of a bone and a ligament, said extended articulating surface member has an inner bone engaging side including a plurality of intersecting flat planar bone engaging surfaces that each face the anchoring stem and an outer articulating surface that is opposite to the inner bone engaging side, the outer articulating surface is curved along substantially its entire length and is substantially congruent with said exterior hemispherical articulating surface, wherein at least two of the intersecting flat planar bone engaging surfaces define a planar “V” shaped inner surface extending generally parallel to the anchoring stem and defined only on the extended articulating surface member.
