A surgical kit includes a shield for covering a portion of the spine of a subject. The shield can include an attachment portion adapted to engage a bone fixation assembly which is adapted to be fixed on multiple vertebra bones of the subject. The bone fixation assembly can include a vertebra joining member secured between two bone anchors. Each bone anchor can include a fastener portion adapted to be implanted into a vertebra bone and a head coupling portion adapted to secure the vertebra joining member. The shield can be coupled to the bone fixation assembly via separate coupling elements, such as a clip or an adjustable link secured between two vertebra joining members of the bone fixation assembly. Alternatively, the shield can include an integral attachment portion configured to engage the bone fixation assembly directly.

A pedicle screw for spinal fixation having a bone fastener portion a permanent rod coupling, a breakaway portion connected to the permanent rod coupling and a temporary rod coupling. A permanent rod can be positioned in the permanent rod coupling and a temporary rod can be positioned in the temporary rod coupling and when the temporary rod is not needed the temporary rod coupling can be removed by separation at a breakaway portion.

A rod connector device includes a first clamp having, on one side thereof, a first grip groove and a first grip expansion groove sequentially connected to each other, a second clamp contacting the first clamp, the second clamp having, on another side thereof, a second grip groove and a second grip expansion groove sequentially connected to each other, a grip applying a binding force to a first rod and a second rod, when the first and second clamps are connected to each other so that the first and second grip expansion grooves communicate with each other, and the first and second rods are grip-secured in the first and second grip grooves.

Translation screw assemblies that can include a screw, housing, load plate, and collet are described herein. The translation screw assembly advantageously allows for relative translation, angulation or pivoting, and/or rotation between the screw and the housing. Occipital plate assemblies are also described herein. An occipital plate assembly can include a plate body and one or more rod receiving assemblies. The plate assembly can include an occipital protuberance tab that can be bent relative to or sheared off from the plate body. The rod receiving assembly can include a pivot post, housing, clamp plate, and retaining washer. The rod-receiving assemblies advantageously allow for relative medial-lateral translation, medial-lateral angulation, and/or cranial-caudal angulation between the rod-receiving assemblies or portions thereof (e.g., the housings) and plate body.

Spine rods are secured together by a crosslink which includes a central body with an arch therein curving around a gap, which allows a spinous process of an adjacent vertebrae, or other anatomical structure, to be located therein. The crosslink includes left and right extensions in a preferred embodiment which are movable relative to the body to accommodate both width adjustment for the crosslink and pivoting of distal ends of the crosslink relative to each other and relative to the body. After movement is accommodated, joints between the extensions in the body can be tightened to eliminate further movement. Clamps at distal ends of the crosslink secure the crosslink to adjacent spine rods. The arch has a bend angle above a horizontal plane to further facilitate avoiding interference with anatomical structures. The arch can be further bent if needed to a desired angle.

A pedicle screw implant construct kit, comprising at least one pedicle screw, at least one collar comprising a recess for receiving a rod, the collar configured to be coupled to a head of the pedicle screw, an elongated rod for connecting the collar to one more additional collars to couple between the pedicle screw and one or more additional screws, and a locking ring sized to be positioned over at least a distal portion of the collar to restrain relative movement of the screw head and rod by exerting radial compression force onto the collar. In some embodiments, the components of the kit are comprised of carbon reinforced composite material, optionally with no radiation blocking material. In some exemplary embodiments of the invention, the kit includes two locking rings on a collar, optionally both below the rod.

Connector assemblies, systems, and methods thereof. A connector having body having a first end and a second end; a first connecting member at the first end, the first connecting member having a rod supporting member extending away from the first connector and a passage extending between the first connecting member and the rod supporting member; and a rod extending from the second end. The body and the passage extend co-axially, and a space is provided between the first end and the second end, the space being sized such that a spinal implant screw head is insertable in the space.

Connector assemblies, systems, and methods thereof. A modular connector has a first end that clamps to a first rod in an existing construct and a second end having a modular connection point configured to connect a second rod in a new construct such that the new construct can be extended from the existing construct.

A spinal distraction system, according to one aspect, includes an adjustable spinal distraction rod comprising first and second members, the adjustable spinal distraction rod configured for non-invasive elongation of the first and second members. The system includes an anchor rod configured for mounting to a bone of a subject, the anchor rod having one or more spring-biased tabs disposed at one end thereof, and a connector having first end and a second end, the first end having a receiving cup configured for detachable mounting on the anchor rod, wherein the one or more spring-biased tabs are configured to engage with an inner surface of the receiving cup, the connector having a second end operatively coupled to an end of a first member and wherein the second member is configured for mounting to a second bone of a subject.

A transverse connector for coupling between first and second elongate members of a spinal stabilization system. The transverse connector includes a connector arm, a first coupling assembly proximate a first end of the arm, and a second coupling assembly proximate a second end of the arm. The first and second coupling assemblies are secured to the connector arm through a plurality of mating engagement features, such as dovetail grooves.
