Patent number: 9301765Abstract: A total hip femoral prosthesis provides a shortened neck and high porous coating level. Additionally, a means for strengthening the neck may be incorporated to increase stress transfer to the native bone. A method for reducing potential impingement that results from a high neck resection level includes cutting chamfered surfaces into the bone surrounding the proximal end of the implant. Instrumentation and methods of creating chamfered cuts are disclosed.Type: GrantFiled: February 3, 2012Date of Patent: April 5, 2016Assignee: Chow IP, LLCInventors: James C. Chow, Bjorn N.

Publication number: 20160000578Abstract: A system for spinal surgery includes a prosthesis comprising a plurality of bone anchors which engage an intervertebral construct for fusion or motion preservation. The fusion construct comprises a spacer optionally encircled by a jacket. The motion preservation construct may comprise an articulating disc assembly or an elastomeric disc assembly. Any of the constructs may occupy the intervertebral disc space between adjacent vertebrae after removal of an intervertebral disc. The anchors slidingly engage the construct to securely fix the prosthesis to the vertebrae. The anchors and jacket of the fusion construct provide a continuous load path across opposite sides of the prosthesis so as to resist antagonistic motions of the spine.Type: ApplicationFiled: September 17, 2015Publication date: January 7, 2016Inventors: Hyun Bae, Nicholas Slater, Joshua A. Butters, Daniel F. Justin, Dylan Hushka, Rick B. Delamarter

Patent number: 8864797Abstract: A line lock system may include a line routed through a plate. The plate may have an elongated body with a plurality of passageways. The line is routed to form at least one one-way slide so no knots are required. The system may include filaments routed through the passageways of the plate or around a dogbone feature of the plate. The filaments may be used to toggle the plate after passage through a hole to prevent withdrawal of the plate back through the hole. The system may include a line lock stabilizer or counter-tension tool to stabilize the line lock as the line is adjusted. The system may include a compression limiter to selectively reduce compression in the one-way slide to facilitate adjustment of the line. The line lock stabilizer, counter-tension tool, or compression limiter may be a filament.Type: GrantFiled: September 23, 2011Date of Patent: October 21, 2014Assignee: Coorstek Medical LLCInventors: Daniel F.

Patent number: 8628576Abstract: Systems for interbody fusion of adjacent bone portions may include an expanding implant and related instruments. An expanding implant may be formed as a linkage which is movable between a compact configuration and an expanded configuration. A shaft of the implant may increase and decrease in length to move between the compact and expanded configurations, and an implant width perpendicular to the length may be increased in the expanded configuration. The implant width may increase more in a first direction than a second direction opposite the first direction. An inserter instrument may releasably grasp the spacer and transform the implant between the compact and expanded configurations.Type: GrantFiled: February 14, 2012Date of Patent: January 14, 2014Assignee: IMDS CorporationInventors: Daniel J.
