Patent number: 9968391Abstract: Facet screws comprise a lower portion have lower threads that have a constant outer or major diameter. The lower portion of the facet screws can also have a tapered or conical shape in a direction toward the lower end, and relative to a longitudinal axis, of the facet screw. Therefore, the lower threads closest to the lower end have a greater surface area for engaging the bone of a patient as compared to the lower threads furthest away from the lower end, i.e., closest to the top of the lower threads. One or more of the lower threads also can include certain dimensions and shapes that facilitate insertion and retention of the facet screws in the bone of a patient.Type: GrantFiled: November 8, 2013Date of Patent: May 15, 2018Assignee: Fellowship of Orthopaedic Researchers, LLCInventors: Stephen D. Cook, Shoib Bajaj

Patent number: 9968394Abstract: An instrument for breaking off and retaining the tab of a reduction screw is provided. The instrument includes a breaking arm and a retaining mechanism. The breaking arm is configured to break off an excess portion of the tab of the reduction screw about a weakened section. The retaining mechanism is configured to retain the broken off tab and preventing the tab from falling into a surgical site. The retaining mechanism is further configured to allow the instrument to engage another tab while simultaneously holding a predetermined number of previously broken off tabs. Accordingly, the instrument reduces surgical time as the surgeon may simply move from one reduction screw to another while breaking off the tabs until the instrument can no longer retain additional broken off tabs.Type: GrantFiled: June 1, 2016Date of Patent: May 15, 2018Assignee: Alphatec Spine, Inc.Inventors: Nathan Meyer, Eller Torres
