    摘要： Embodiments include a method for promoting selective tissue attachment to medical implants. By treating implant surfaces where tissue attachment is desired with tissue attachment promoting treatments, and treating implant surfaces where tissue attachment is not desired with tissue attachment inhibiting treatments, selective tissue attachment to medical implants may be achieved. Also, embodiments include an implant with at least one tissue contacting surface and at least one secondary surface where tissue attachment is not desired, and appropriate tissue attachment promoting or inhibiting treatments on the surfaces.

    摘要： A method of making a component of a spinal fixation system. The method may comprise providing a mixture of a powder of at least one metal or metal alloy and a polymeric binder. A metal-injection-molding process may use the mixture to form a component for a spinal fixation system. The components may have varying flexibility across their cross-sections. Also, components are provided that are produced by this process, such as spinal fixation rods and plates.

    摘要： Elongated connecting elements include bodies having anisotropic cross-sectional shapes defining a first moment of inertia about a first bending axis and a second moment of inertia about a second bending axis that is transverse to the first bending axis. The connecting elements are positioned along one or more spinal motion segments and engaged to vertebrae with anchors with the first and second bending axes in the desired orientation relative to the spinal motion segments.

    摘要： Embodiments provide composite components for use in spinal fixation systems. The composite components may comprise polyetheretherketone (PEEK) or another non-resorbable or resorbable polymeric material and at least one metal. Incorporation of PEEK or another non-resorbable or resorbable polymeric material into the components allows average or mean physical properties (e.g., tensile strength, modulus of elasticity, etc.) of the components to be modulated. The composition and orientation of the composite components can be advantageously chosen to produce components with desired physical characteristics.

    摘要： A spinal construct and method for implantation is provided which utilizes a spinal implant adapted for insertion within an intervertebral space between an adjacent pair of vertebral bodies, and an elongate member adapted for anchoring to the adjacent vertebral bodies. The spinal implant defines a first transverse dimension and a different second transverse dimension, and is initially inserted into the intervertebral space while in a first operational configuration wherein the first transverse dimension extends along the height of the intervertebral space. The elongate member is anchored to the vertebral bodies to establish and maintain a select height of the intervertebral space. The spinal implant is then rotated to a second operational configuration wherein the second transverse dimension extends along the height of the intervertebral space. The elongate member serves to maintain the select height of the intervertebral space to provide a controlled amount of compression onto the spinal implant and/or a bone growth promoting material contained therein. The elongate member also serves to resist tensile loads during extensional movement of the vertebral bodies to maintain the vertebral endplates in intimate contact with the spinal implant.
