摘要： An orthopedic component having multiple layers that are selected to provide an overall modulus that is substantially lower than the modulus of known orthopedic components to more closely approximate the modulus of the bone into which the orthopedic component is implanted. In one exemplary embodiment, the orthopedic component is an acetabular shell. For example, the acetabular shell may include an outer layer configured for securement to the natural acetabulum of a patient and an inner layer configured to receive an acetabular liner. The head of a femoral prosthesis articulates against the acetabular liner to replicate the function of a natural hip joint. Alternatively, the inner layer of the acetabular shell may act as an integral acetabular liner against which the head of the femoral prosthesis articulates.

摘要： Medical implants, such as orthopedic implants of the type used in partial or total joint replacement procedures, for example. The implants include a porous substrate, and a bearing portion of a polymeric material, for example, which is at least partially molded within the porous substrate. The bearing portion includes a bearing surface that is exposed to an articulating component of another medical implant, and the porous metal substrate contacts the bone for osseointegration of the bone tissue into the porous substrate to anchor the implant. The porous substrate may include biodegradable carrier materials, in the form of one or more layers, that carry biologically active agents such as antibiotics and bone growth factors, for example. The layers of biodegradable carrier materials may be tailored such that, after implantation of the implants, the biologically active agents are released sequentially and/or over time into the surrounding tissue to reduce the chances of infection and/or to promote osseointegration of the implant, for example.

摘要： A composite interbody vertebral implant for facilitating fusion of adjacent vertebrae. The implant includes a first endplate of a porous metal material and a second endplate of a porous metal material which are configured to allow bone in-growth. The implant also includes a polymeric body positioned between and bonded to the first and second endplates such that polymeric material of the polymeric body is impregnated into pores of the first and second endplates to bond the components together. The implant may include a cavity extending through the composite implant configured to receive bone growth material to facilitate fusion between a first vertebra and a second vertebra.

摘要： A vertebral fixation system including an elongate rod and a vertebral anchor for securement to a vertebra. The vertebral anchor includes a head portion for receiving a portion of the rod. The elongate rod may be formed of a material having a modulus of elasticity less than or equal to 110 GPa and an ultimate strength greater than 1 GPa. The elongate rod may have a structural bending stiffness in the range of about 500,000 N-mm2 to about 2,000,000 N-mm2 or about 1,250,000 N-mm2. In some instances, the elongate rod may be formed of a beta titanium alloy such as high strength Ti-15Mo-5Zr. In some instances the elongate rod has a diameter in the range of about 3.25 millimeters to about 4.5 millimeters. Various elongate rods including regions for receiving a flexible member along an exterior surface of the elongate rods are also provided.
