Patent number: 9949762Abstract: A posterior vertebral stabilizer has a resilient member such as a linear spring, which operates in tension and compression. The resilient member may be kept straight by a stabilization rod extending through the spring, or by a telescoping assembly that encases the resilient member. The ends of the stabilizer are attachable to pedicles of adjacent vertebrae so that the stabilizer adds stiffness to control flexion and extension of the vertebrae. Two such stabilizers may be used, and may be connected together by a crosslink designed to limit relative rotation of the stabilizers. Thus, the stabilizers may restrict axial rotation and lateral bending between the vertebrae, while permitting stiffened flexion and extension. Such stabilizers help provide the stiffness of a healthy intervertebral disc. In the event that fusion of the joint becomes necessary, a set screw or other component may be used to further restrict flexion and extension.Type: GrantFiled: October 11, 2016Date of Patent: April 24, 2018Assignee: Stryker European Holdings I, LLCInventors: T.

Patent number: 7867280Abstract: A method includes the acts of sliding a first end of a flexible first line through a channel in a first bone anchor. A portion of the first line is connected to an implant having a top articular surface and an opposing bone apposition surface. The first line extending between the implant and the first bone anchor is then tensioned. While the tensioning force is maintained on the first line, the first line is secured to the first bone anchor.Type: GrantFiled: July 28, 2004Date of Patent: January 11, 2011Assignee: Zimmer, Inc.Inventors: E.

Publication number: 20100204798Abstract: A system and method facilitate insertion of a fusion implant into the intervertebral space of a spine. The fusion implant may have a first bone engaging surface and a second bone engaging surface. An attachment interface on an insertion tool allows the implant to be releasably secured to the insertion tool, so that the insertion tool may be detached from the implant without requiring a threaded coupling. The implant may be positioned in two different orientations with respect to the insertion tool to permit usage of two different techniques to insert the implant into the intervertebral space. A recessed support member in the implant creates gaps between bone facing surfaces and the vertebral bodies such that bone graft material may occupy the gaps. The implant includes embedded radiographic markers which facilitate radiographic detection of the orientation of the implant through the surrounding tissue.Type: ApplicationFiled: April 21, 2010Publication date: August 12, 2010Applicant: STRYKER SPINEInventors: Daniel E.

Patent number: 7578824Abstract: A guide assembly for forming a tunnel through a proximal end of a tibia includes a brace having a first end and an opposing second end. A template is mounted on the first end of the brace. The template is adapted to rest on a lateral or medial facet at a proximal end of the tibia. A tubular guide sleeve has a proximal end and an opposing distal end. The tubular guide sleeve is adjustably mounted on the second end of the brace such that when the template is disposed on the lateral or medial facet of the tibia, the distal end of the tubular guide sleeve can be selectively biased against a lateral, medial, or anterior side of a proximal end of the tibia.Type: GrantFiled: December 30, 2003Date of Patent: August 25, 2009Assignee: Zimmer, Inc.Inventors: Daniel F.

Patent number: 7507242Abstract: 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: GrantFiled: November 15, 2004Date of Patent: March 24, 2009Assignee: Facet SolutionsInventors: Daniel J.
