    摘要: 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).

    摘要: An orthopedic prosthetic implant comprises a metal alloy stem element (13, 63, 113) which has one end portion (19, 69, 119) constructed to reside in the medullary cavity of a bone and an integral connector (23, 73, 123) at the opposite end, to which a crystalline brittle head (17, 67, 117) preferably made of pyrocarbon-coated graphite is joined. The effective joinder of the head to the stem element is achieved through a polymeric insert (15, 65, 115) which has selected elastic properties. The design and material of the polymeric insert allow it to be securely received within an interior cavity (35, 77, 131) of the pyrocarbon-coated graphite head and mated to the stem connector in an either rigidly or bi-polar arrangement. Such joinder allows the composite implants that utilize the most desirable properties of metallic and brittle crystalline materials.

    摘要: Implant devices, and method of using the same, are provided. The implant devices have a head and a stem. The head has an upper surface, an anterior surface, a posterior surface, a lateral surface and a lower surface. The anterior surface, the lateral surface, and the lower surface are approximately perpendicular to and intersect each other. The anterior surface and the posterior surface are approximately parallel to each other. Preferably, the upper surface has a general shape of at least a portion of a superior articular surface of a talus and at least a portion of a medial articular surfaces of a talus. The stem has a truncated conical portion and a cylindrical portion. The cylindrical portion is affixed to the lower surface of the head, and the truncated conical portion is affixed to the cylindrical portion.

The head interfaces with human bone, and its effective joinder to the stem element is achieved through a polymeric insert (15, 65, 115) of proportional shape and design which has selected elastic properties. The design and material of the polymeric insert allow it to be securely received within an interior cavity (35, 77, 131) of the pyrocarbon-coated graphite head and mated to the stem connector in an either rigidly or bi-polar arrangement. The method of joinder allows the construction of composite implants that utilize the most desirable properties of metallic and brittle crystalline materials.
