摘要： A method and apparatus for adjusting the modulus of elasticity, flexural strength, or porosity of metal and ceramic implants is disclosed in one embodiment of the invention as including a green tape comprising metal or ceramic particles, or a combination thereof, for incorporation into a solid implant structure (44). Apertures (32) are cut in selected regions of the green tape (34) in order to create a desired pore structure in the solid implant structure (44). This pore structure may be designed to give the solid structure (44) a desired modulus of elasticity, flexural strength, or porosity as well as to promote bone ingrowth. The green tape (34) may then be layered in an orientation that will provide the desired pore structure and the metal or ceramic particles and layers may be fused together to create the solid implant structure (44).

摘要： The invention relates to an orthopedic implant made of a ceramic metal composite. The composite (28, 48, 54) includes one phase that is a biocompatible metal or metal alloy and a second phase of ceramic particles examples of which include carbides, nitrides and/or oxides. In some embodiments, the implant comprises a homogeneous ceramic layer (24) as part of a multi-layered composition. In some embodiments, the multilayered composition comprises a homogeneous metal layer (32).

摘要： An intervertebral disk prostheses for the total replacement of an intervertebral disk of the lumbar and cervical spine has an upper plate having upwardly projecting formations anchoring it to an upper vertebra on its upper face and a concavity on its inner face surrounded by an edge. A lower plate is provided with downwardly projecting formations anchoring it to a lower vertebra on its lower face and a flat inner face surrounding a groove extending front-to-back. A middle plate between the upper and lower plate has on its upper face a convexity that is identically or differently shaped to the concavity on the inner face of the upper plate and a ridge extending front-to-back surrounded by a flat lower face of the middle plate. The ridge has flanks and the groove houses the ridge of the middle plate and permits the ridge to slide front-to-back in the groove.
