Patent number: 11730528Abstract: Misaligned bones on opposite sides of a joint are aligned using a first rigid extension securable to one of the misaligned bones using a particular surgical approach, and a second rigid extension having a contacting surface positionable in contact with the other the two misaligned bones from the same surgical approach. The first and second rigid extensions are moved with respect to each other using a lever, whereby a pulling force is exerted on one of the bones, and a pushing force on the other, thereby aligning the first and second misaligned bones.Type: GrantFiled: January 10, 2020Date of Patent: August 22, 2023Assignee: Globus Medical, Inc.Inventors: Marcin Niemiec, Duncan Sibson, Noah Hansell, Chad Glerum, Colm McLaughlin, Daniel Davenport, Mark Weiman, Jason Gray, Khiem Pham, Michael Black, Ben Silber, Mark Fromhold, Andrew Iott, Kathleen Hill, John Gilbert, Richard Castle

Publication number: 20230190336Abstract: A modular uniplanar pedicle screw assembly for use with a polyaxial bone fastener. The modular assembly comprises a uniplanar tulip assembly adapted to be coupled to a head of the polyaxial bone fastener, wherein the uniplanar tulip assembly includes a longitudinal slot. The modular assembly further includes an adapter having a lower portion and an upper portion. The lower portion is sized and shaped to be received in a recess of the bone fastener head.
