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.

System and method for multiple level facet joint arthroplasty and fusion

A crosslink is provided for securing orthopedic implants, such as facet joint replacement implants, together. The crosslink has a pair of implant coupling components, a pair of rod coupling components, a rod, and a pair of fasteners. Each facet joint implant may include a semicylindrical interface received in a resilient member of the corresponding implant coupling component to permit relative cephalad/caudal adjustment between the crosslink and the implants. The resilient members grip the semicylindrical interface of the implant to enable at least temporary attachment of the implant coupling components to the implants independently of the rod. Clocking features on the semicylindrical interfaces and on the interfacing areas of the implant coupling components and rod coupling components may limit assembly of the crosslink to discrete relative orientations and prevent play after assembly. The fasteners secure the rod coupling components to the rod at the desired positions along the rod.

Facet joint implant crosslinking apparatus and method

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.

Facet joint replacement

Superior and/or inferior facets of one or more facet joints may be replaced by superior and/or inferior facet joint prostheses. In one embodiment, a kit of superior or inferior prostheses is provided, in which the prostheses have at least two dimensions that vary among members of the kit independently of each other. Each prosthesis may have a bone engaging surface having a surface that is polyaxially rotatable against a corresponding resection of a vertebra. Each prosthesis may also have an articulating surface shaped such that, after attachment to the spine, the replaced or partially replaced facet joints provide a larger medial-lateral range of motion when the spine is flexed than when the spine is extended. Crosslinks may be used to connect left and right prosthesis together in such a manner that they are stabilized in a position in which they are seated directly against the vertebra.
