Publication number: 20120016372Abstract: A facet joint replacement system includes an inferior implant with an inferior articular surface, a superior implant with a superior articular surface, and an optional crossbar. The inferior implant and the superior implant are each polyaxially adjustably connected to fixation elements which anchor the implants to adjacent vertebrae. The optional crossbar may be polyaxially adjustably connected to bilateral implants. The system components may be provided in kits which provide components of various sizes and shapes. A set of surgical instruments may facilitate implantation of the facet joint replacement system by providing tools for bone preparation, trialing, implant insertion, implant alignment, and lock-out of modular interconnections.Type: ApplicationFiled: December 3, 2009Publication date: January 19, 2012Applicant: FACET SOLUTIONS, INC.Inventors: Andrew R.

Patent number: 7815648Abstract: A measurement tool is designed to measure the relative displacements between two bony landmarks of a spine, such as pedicles and facet surfaces. The measurement tool may have a registration interface designed to be registered to a first bony landmark, and a contact feature shaped to contact a second bony landmark. The registration interface may be registered to a frame rigidly coupled relative to the first bony landmark. The measurement tool also has a displacement structure that permits motion of the contact feature relative to the registration interface along multiple dimensions. The displacement structure may have two or three sliding joints that enable relative translation along orthogonal axes. Each sliding joint may have a rod with a plurality of markings that can easily be read to acquire measurement from the displacement structure.Type: GrantFiled: September 29, 2008Date of Patent: October 19, 2010Assignee: Facet Solutions, IncInventors: Daniel J.

Patent number: 7758581Abstract: A reamer may be designed to engage a guide member, such as a guide wire, implanted in bone at any of a plurality of relative orientations such that the resulting resection of the bone does not depend on the relative orientation. The reamer may have a shaft that receives torque and a reaming head with a cavity into which a protruding portion of the guide wire is insertable. The cavity may have a generally conical shape capable of receiving the guide wire at a variety of relative orientations. The orientation of the reaming head is determined not by that of the guide wire, but by a stationary frame to which the reamer is coupled. The reamer may optionally have an offset assembly that causes the reaming head to rotate about an axis displaced from that of the shaft to reduce the size of the incision required to reaming head.Type: GrantFiled: March 24, 2006Date of Patent: July 20, 2010Assignee: Facet Solutions, Inc.Inventors: Alan Chervitz, Daniel J.

Patent number: 7753937Abstract: 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: GrantFiled: June 2, 2004Date of Patent: July 13, 2010Assignee: Facet Solutions Inc.Inventors: Alan Chervitz, Daniel F.

Patent number: 7722647Abstract: A facet joint replacement implant may have a posterior stabilization surface designed to restrict posterior motion of a vertebra with respect to an adjacent, inferior vertebra. The facet joint replacement implant replaces the natural articular surface of one of the vertebrae, and articulates with a natural articular surface or with an articular surface of a second implant on the other vertebra. The posterior stabilization surface may be on a posterior flange of a superior facet joint implant, which extends posteriorly of a corresponding inferior facet joint implant. The inferior facet joint implant has an abutment surface that abuts the posterior stabilization surface as the superior vertebra begins to move posteriorly with respect to the inferior vertebra, thereby limiting the posterior motion.Type: GrantFiled: March 14, 2005Date of Patent: May 25, 2010Assignee: Facet Solutions, Inc.Inventors: Jeffery C. Wang, T. Wade Fallin, Robert W. Hoy, Alan Chervitz

Patent number: 7691145Abstract: Cephalad and caudal vertebral facet joint prostheses and methods of use are provided. A pair of fixation elements are adapted to be secured within a vertebra in an orientation that best assures a secure and durable attachment to cortical and/or cancellous bone. Artificial facet joint surfaces are mounted on the fixation elements, either directly or with the aid of a support. The artificial facet joint structure may be carried by an arm. The artificial facet joint structure is adapted for articulation with a complementary natural or artificial facet joint structure. Bilateral prostheses may by coupled by a brace to further secure and stabilize the prostheses.Type: GrantFiled: October 25, 2004Date of Patent: April 6, 2010Assignee: Facet Solutions, Inc.Inventors: Mark A.
