Patent number: 9522020Abstract: A bone screw, which can be a pedicle screw, is generally tulip-shaped. A bore in the bottom of the tulip permits a threaded shaft to be partially inserted into the open interior of the tulip. A seat is formed on the threaded shaft and receives the bottom of the tulip, and prevents the threaded shaft from being inserted too far into the tulip. A saddle is positioned in the interior of the tulip and receives the end of the threaded shaft on one end and can include a trough on its opposite face which can receive a rod that connects together two or more such assemblies. A retaining screw threads into the upper interior surface of the tulip to hold the subcomponents together.Type: GrantFiled: August 8, 2012Date of Patent: December 20, 2016Assignee: SPINAL U.S.A.Inventors: Adam Cermak, Jeffrey Johnson, Gil Aust
