A humeral head resurfacing implant (11) that has a modulus of elasticity close to that of human cortical bone as a result of its design from an integral substrate of isotropic graphite covered completely with a reinforcing layer of dense isotropic pyrolytic carbon. A carefully engineered cruciform stem (15) extends from the axial center of a flat distal circular surface (23) of a spherical cap portion (19) of the implant head located within the confines of a surrounding skirt portion (21).
