  • Patent number: 11045212
    Abstract: An instrument for drilling a hole for a bone screw comprises a shaft having a primary drill fluted portion, a shank, and a middle portion there between. Part of an outer surface of the shaft's middle portion is non-curved. A sleeve surrounds the shaft. The sleeve has an inner surface that is complementary to the outer surface of the shaft's middle portion such that the sleeve slides with respect to the shaft. The sleeve's inner surface contacts the outer surface of the shaft's middle portion at the non-curved part such that the shaft can transmit torque to the sleeve. A countersink drill bit is provided at an end of the sleeve proximate the shaft's primary drill fluted portion. A locking mechanism selectively holds the sleeve in a fixed position with respect to the shaft, locating the countersink drill bit at a selected position with respect to the shaft's drilling end.

  • Patent number: 11020241
    Abstract: A spinal interbody implant includes a two-component cage and expander. The two-component cage, when assembled, accepts the expander through a reverse dovetail configuration between the assembled cage and the expander. The expander has a pair of legs that move within and along lateral channels formed by and between the two cage components for increasing the height of the two cage components relative to one another. The amount of expansion of the cage is determined by the height of the pair of expander legs. The cage accepts different expanders each having pairs of legs of different heights in order to provide different amounts of cage expansion and thus the interbody implant. The front of each expander leg is arch shaped for reception in the lateral channels of the assembled cage and to progressively expand the two cage components relative to one another as the expander is received by the assembled cage.

  • Patent number: 10993750
    Abstract: Variable angle holes in bone plates that are structured to facilitate the formation of axial compression or tension of a bone, or which can assist in bone distraction. The variable angle hole can extend about a central axis and includes an inwardly extending wedge wall. The variable angle hole can be sized to receive insertion of a fixation element at a location at which a central longitudinal axis of the fixation element is axially offset from the central axis of the variable angle hole by an offset distance at least when the fixation element is initially driven into bone at least in a transverse direction. The wedge wall can be configured to be engaged by a portion of the fixation element in a manner that axially displaces at least one of the bone plate, the fixation element, and/or bone(s) in a direction that can generally reduce or increase the offset distance.
