摘要： 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.

摘要： 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.

摘要： A frame is attachable to first and second bone portions of a patient to facilitate measurement and resection of one or more bony landmarks. The frame has two anchoring features, each of which has a semispherical surface that permits rotational adjustment of the frame against the bone portions until the frame is secured. A bridging structure couples the anchoring features together such that the anchoring features are lockably movable with respect to each other. The bridging structure may have three linear sliders that provide the relative motion. A locking mechanism exerts pressure on all three sliders to lock them in place. An external anchoring feature enables attachment of the frame to a stationary reference to stabilize the frame. The frame also has registration features that permit attachment of measurement or resection tools to the frame. The frame is particularly useful for measuring and resecting spinal facets for facet replacement.
