    摘要: A prosthesis for the replacement of at least a portion of the bone of a facet located on a mammalian vertebra, comprising: an articulating surface that articulates with another facet; a bone contacting surface that contacts a surface of the vertebra, the articulating surface being connected to the bone contacting surface; and a fixation element that attaches the bone contacting surface to the vertebra, the fixation element being adapted for implantation into an interior bone space of a pedicle of the vertebra; wherein the prosthesis is configured so that no portion of the prosthesis contacts the posterior arch of the vertebra.

    摘要: A method for reconstructing a ligament. In one form of the invention, there is disclosed a method for securing a graft ligament in a bone tunnel, the method comprising the steps of: (1) forming a first bone tunnel in a bone, and forming a second bone tunnel in the same bone, the second bone tunnel being transverse to, and intersecting, the first bone tunnel; (2) positioning a flexible member in the second transverse bone tunnel so that the flexible member extends across the first bone tunnel, and positioning the graft ligament in the first bone tunnel, independently of the flexible member, so that the graft ligament is looped over the flexible member; and (3) positioning a crosspin over the flexible member and in the second transverse bone tunnel so that the graft ligament is looped over, and may be supported by, the crosspin.
