Claim:
A monolithic humeral head resurfacing implant comprising: a head having: a hemispherical exterior articulating surface defining a terminating rim; a concave interior surface opposite said hemispherical exterior articulating surface; an integral straight anchoring stem having a textured outer surface configured to be directly coupled to bone, said anchoring stem extending from said interior surface and being integral with the interior surface; and an extended articulating surface defining a flange axially protruding from only a portion of the terminating rim of said hemispherical exterior articulating surface, said extended articulating surface operable to articulate with at least one of a bone and a ligament, said extended articulating surface having a pair of interior intersecting flat planar surfaces, said interior intersecting flat planar bone bearing surfaces being generally parallel to the integral straight anchoring stem, wherein said extended articulating surface is located in a lateral region of said head when implanted in a patient, and wherein said pair of interior intersecting flat planar surfaces define a planar “V” shaped inner surface defined on the extended articulating surface.
