Publication number: 20090030461Abstract: 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.Type: ApplicationFiled: September 29, 2008Publication date: January 29, 2009Applicant: FACET SOLUTIONS, INC.Inventors: Robert W. Hoy, Daniel J. Triplett, T. Wade Fallin, Alan Chervitz, Daniel F. Justin

Publication number: 20090024134Abstract: 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.Type: ApplicationFiled: September 29, 2008Publication date: January 22, 2009Applicant: Facet Solutions, Inc.Inventors: Daniel J Triplett, T.

Patent number: 7309340Abstract: A bone plating system invention is shown comprising a bone plate and bone fasteners. The bone plate has a top portion, a bottom portion, and an interior middle portion. The fastener-retaining passageway extends through the plate. The fastener-retaining passageway comprises an upper portion having an inwardly projecting capture lip. The capture lip has a first diameter. The fastener-retaining passageway also has a middle undercut portion that has a second diameter. The second diameter is larger than the first diameter. The plate also has at least one access channel extending through the capture lip so as to communicate with the interior middle portion of the plate. The fastener comprises a shaft, a fastener engager means extending from, disposed on or coupled with the shaft for engaging bone and a head mounted on the shaft having a radially elastic member.Type: GrantFiled: June 20, 2003Date of Patent: December 18, 2007Assignee: MedicineLodge, Inc.Inventors: T.

Patent number: 7074237Abstract: 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.Type: GrantFiled: April 22, 2003Date of Patent: July 11, 2006Assignee: Facet Solutions, Inc.Inventors: E.
