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.

Patent number: 8012217Abstract: Implant devices, and method of using the same, are provided. The implant devices have a head and a stem. The head has an upper surface, an anterior surface, a posterior surface, a lateral surface and a lower surface. The anterior surface, the lateral surface, and the lower surface are approximately perpendicular to and intersect each other. The anterior surface and the posterior surface are approximately parallel to each other. Preferably, the upper surface has a general shape of at least a portion of a superior articular surface of a talus and at least a portion of a medial articular surfaces of a talus. The stem has a truncated conical portion and a cylindrical portion. The cylindrical portion is affixed to the lower surface of the head, and the truncated conical portion is affixed to the cylindrical portion.Type: GrantFiled: January 13, 2009Date of Patent: September 6, 2011Assignee: Fellowship of Orthopaedic Researchers, LLCInventors: Peter Strzepa, Stephen D Cook
