    摘要: A prosthesis for the replacement of multiple diseased or traumatized spinal facets comprises a portion that replaces at least a bony portion of the facets to be replaced and where the prosthesis attaches to the vertebra in a manner that does not require attachment to, or abutment against, the lamina. Multiple configurations of the prosthesis provide for replacement of the two inferior facets, the two superior facets, a superior and inferior facet, or all four facets. A method of installing the prosthesis is provided that is comprised of the steps of resecting at least a portion of the facets that carry the diseased or traumatized spinal facets and attaching the prosthesis in a manner that does not require attachment or abutment against the lamina.

    摘要: A dynamic spine prosthesis (such as a facet joint prosthesis having an articulation surface configured to articulate with a corresponding facet joint element) that has a fixation element with an elongated bone entry portion defining a longitudinal axis and a dynamic spine prosthesis component connected to the fixation element at a connection location by an adjustable connection. The adjustable connection has first and second washers each rotatably supported by the fixation element and each having an angled contact surface in a plane not perpendicular to the longitudinal axis of the fixation element, with the connection location being between the bone entry portion and the first and second washers.

    摘要: An orthopedic fastener is designed to attach an implant to bone in such a manner that, until the fastener is tightened, the implant may be rotationally adjusted against the bone. The implant may have a semispherical bone apposition surface that permits polyaxial rotation of the implant against the bone. The orthopedic fastener has an interpositional member and a compression member. The interpositional member may be a split ring with a conical exterior surface that mates with a conical surface of the implant. The compressing member has a threaded bore that engages a proximal end of a fixation member implanted in the bone such that, in response to rotation of the compression member, the interpositional member is sandwiched securely between the implant and the compression member. The conical surface of the implant compresses the interpositional member about a semispherical surface of the compression member, thereby restricting rotation of the implant.

    摘要: Facet joint replacement implants may be designed for use on multiple adjacent vertebral levels. Each superior implant may have a substantially semispherical concave surface, and each inferior implant may have a cooperating semispherical convex surface that is deformable to enable it to be pressed into the superior implant concave surface to fix the relative orientations of the superior and inferior implants. Thus, the inferior implant may be attached to the same pedicle as the superior implant, but may also be oriented independently of the superior implant and then fixed in position. Similar mounting structures may be used to attach one or more fusion implants to a level adjacent to that of a facet joint replacement implant.
