  • Patent number: 11185352
    Abstract: A pivotal bone anchor assembly includes a receiver having upright arms defining a receiver channel for receiving an elongate rod, and an axial bore extending downward from the receiver channel to a bottom opening. The upright arms include break-off extensions, outer horizontally extending curvate tool engagement grooves, and side apertures extending inwardly from outer surfaces of the upright arms to deformable crimp wall portions adjacent the axial bore. The assembly also includes a shank having an anchor portion and an integral upper portion that is positionable in the axial bore of the receiver with the shank extending downward through the bottom opening. The assembly further includes an insert with an insert channel positionable within the axial bore and having opposing depressions formed into side surfaces that are configured to cooperate with the crimp wall portions of the receiver to maintain the insert channel in alignment with the receiver channel.

  • Patent number: 11185349
    Abstract: A pivotal bone anchor assembly includes a receiver with an open channel configured to receive an elongate rod and a central bore having an inwardly protruding interference structure with a discontinuous annular upper surface. The assembly also includes a shank having a head positionable within the central bore and an anchor portion for fixation to the bone of a patient, and an insert positionable into the central bore in an initial position that is constrained from vertical movement in at least one direction by engagement between outer curvate side surfaces of the insert and the discontinuous annular upper surface. The insert is configured for forced downward displacement within the central bore by tooling from the initial position to a lower position in which the outer curvate side surfaces of the insert are wedged against the interference structure to inhibit the insert from moving back up within the central bore.

  • Publication number: 20210361323
    Abstract: A polyaxial bone screw assembly includes a threaded shank body having an upper portion, a receiver, a compression insert and an articulation structure made from at least two discrete pieces. The shank upper portion cooperates with the compression insert to place the retainer in frictional engagement with the receiver. The geometry of the retainer structure pieces corresponds and cooperates with the external geometry of the shank upper portion to frictionally envelope the retainer structure between the capture structure and an internal surface defining a cavity of the receiver.

  • Publication number: 20210338295
    Abstract: A pivotal bone anchor assembly includes a receiver having a lower portion defining a cavity with a retention structure proximate a lower opening and an upper portion defining a channel, and a shank having a capture portion with a spherical outer surface, an anchor portion opposite the capture portion for fixation to the bone, an internal drive structure opening onto a top end, an upward-facing planar surface surrounding the internal drive structure above the spherical outer surface, and a central bore extending from the internal drive structure down to the bottom of the anchor portion. The assembly also includes a retainer having an outer surface engageable with the retention structure and an inner surface engageable with the spherical outer surface, upon an uploading of the capture portion through the lower opening, so as to capture and hold the capture portion within the cavity with the shank being pivotal with respect to the receiver prior to securing a fixation rod within the channel with a closure.

  • Patent number: 11160581
    Abstract: A pivotal bone anchor assembly includes a shank having an upper capture portion and a lower anchor portion for fixation to the bone of a patient, and a receiver having an open channel for receiving a rod and a lower cavity for pivotably supporting the capture portion in a non- locked configuration. The assembly also includes an insert positionable into the receiver separate from the capture portion and thereafter downwardly deployable by tooling to apply a frictional force toward the capture portion that holds the angular position of the shank relative to the receiver prior to locking the assembly with a closure, with exterior surfaces of the insert entering into a non-threaded frictional biased engagement with interior surfaces of the receiver to maintain the insert in the deployed position. The exterior surfaces of the insert are further disengageable from the interior surfaces of the receiver by tooling to re-establish pivotal movement between the shank and the receiver.

  • Patent number: 11147592
    Abstract: A pivotal bone anchor assembly includes a receiver having a first channel configured to receive an elongate rod and an axial bore with a bottom opening, and a shank having a head portion positionable into the axial bore with the shank extending downward through the bottom opening. The assembly also includes an insert positionable into the axial bore above the head portion and having a second channel alignable with the first channel, opposite extensions extending outwardly in the direction of the channels to block rotation between the receiver and the insert, and upward-facing surfaces located radially outward from a central opening. The upward-facing surfaces are configured for releasable compressive engagement by a compressing tool after the elongate rod is received within the channels and prior to a final locking of the assembly with a closure top, so as to provisionally lock the shank from pivoting with respect to the receiver.

  • Patent number: 11147597
    Abstract: A hinged bone screw and tool set is used for implanting such bone screws in a human spine, followed by the implantation of a longitudinal connecting member into the bone screws. The hinged bone screw includes a shank with an upper portion and a receiver with integral arms forming a U-shaped channel. A lower curved seat partially defining the U-shaped channel cooperates with an upper portion of the bone screw shank for hinged movement of the shank with respect to the receiver. The tool set includes an insertion tool, a bone screw driver, a reduction tool and a closure starter. The insertion tool includes a bone screw attachment structure and a laterally opening channel. The insertion tool further includes a threaded portion for cooperation with the reduction tool to provide synchronized placement of a closure structure in the bone screw receiver while reducing and capturing a longitudinal connecting member within the receiver.

  • Patent number: 11134993
    Abstract: A pivotal bone anchor assembly includes a receiver with an open channel and a central bore having opposed recessed retaining structures with downwardly-facing surfaces located below a closure mating structure, and a shank having an upper capture portion positionable into the central bore and having a partially spherical lower surface that is slidably engageable with a partially spherical seating surface adjacent a bottom opening of the receiver to provide for pivotal motion of the shank with respect to the receiver. The pivotal bone anchor assembly also includes a compression insert disposed within the central bore having an upper rod-seating surface between insert arms and flange structures projecting laterally outward from the insert arms and configured to snap into the recessed retaining structures to inhibit axial rotation and upward movement of the compression insert within the receiver after the upper capture portion of the shank is positioned within the central bore.
