    摘要: A system for restoring articular cartilage has a cover, an anchor, and a tether that cooperate to retain graft tissue with respect to a graft site. The cover is attached to the anchor via the tether. The tether passes through a tunnel through a bone to which the articular cartilage is attached. The tunnel connects the graft site to an anchoring side of the bone. The anchor is retained proximate the anchoring side such that tension in the tether keeps the cover in place over the tissue graft to capture the tissue graft at the proper position with respect to the graft site. The cover and/or the anchor may be bioabsorbable. The cover may be perforated to permit fluids to access the tissue graft from outside the cover to enhance incorporation of the graft tissue with the graft site. The cover may be formed of rigid or flexible materials.

    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 prosthetic replacement for a posterior element of a vertebra comprising portions that replace the natural lamina and the four natural facets. The prosthetic replacement may also include portions that replace one or more of the natural spinous process and the two natural transverse processes. If desired, the prosthesis replacement may also replace the natural pedicles. A method for replacing a posterior element of a vertebra is also provided.
