Abstract: Embodiments of the present invention are directed to an occipital plate for fixating the occipital/cervical junction between cranium and the spine configured to provide multi-axial adjustment for the rod connectors including Anterior/Posterior movement, Medial/Lateral movement and Converging/Diverging movement. Some embodiments of the present invention use a variety of components to achieve a range of motion in several different axes. This extended range of motion allows the plate to adapt to the surrounding anatomy as well as making it more facile to adapt to a posterior rod fixation system.

Abstract: A derotation reducer linkage with polyaxial locking connector for use with screw reducers/extenders in spinal fusion surgery.

Abstract: A multi-level compressor/distractor instrument that provides both linear and lordotic/kyphotic induced compression and distraction.

Abstract: A rod reducer designed to deliver a set screw by way of a decoupled ram and driver shaft. The driver shaft secures and delivers the set screw while the ram applies the load to the rod for reduction. By separating the ram and driver, the rod is reduced down below the start of the female threads, allowing for the set screw to be started by the driver, avoiding binding and additional steps.

Abstract: A stylet screw driver assembly having a screw driver/ratcheting handle assembly which houses a stylet, pre-assembled to a set length based on the screw length in use, fixed in place by a spring loaded button mechanism located on the proximal end of the ratcheting handle. The spring loaded button mates with the stylet assembly, providing various stylet protrusion lengths.

Abstract: A uniplanar screw assembly having a pedicle screw with a threaded shaft and spherical head with a circumferential groove; a U-shaped tulip having a spherical bottom sized to receive the spherical head of the pedicle screw, a bottom opening for the threaded shaft to go through, and diametrically opposed pin openings; two pins sized for insertion in the pin holes of the U-shaped tulip being configured to slideingly engage the circumferential groove in the spherical head; wherein the engagement of the diametrically opposed pins and circumferential groove limits a lateral motion of the pedicle screw with respect to the U-shaped tulip in a plane that pins are symmetric to, while allowing a rotational motion between the pins and groove so that the pedicle screw may rotate with respect to the U-shaped tulip.

Abstract: An expandable cage for placement between adjacent vertebrae having two or more upper and lower end plates having compound-angled slots, ramps or rails, and a drive means having corresponding compound-angled slots, ramps or rails configured to slidingly engage the compound-angled slots, ramps or rails of the two or more upper and lower end plates, wherein movement of the drive means in a first direction moves the two or more upper and lower end plates away from each other both vertically and horizontally to expand both a height and a width of the expandable cage from a collapsed state to an expanded state.

Abstract: A variable screw top cross connector for connecting spinal rods is provided that is designed to attach between spinal screws to add rigidity to a construct. The variable screw top cross connector includes multiple adjustment options (elongate (x axis)/pivot (x axis)/pivot (z axis)/medial-lateral pivot (y axis), and has a friction fit mechanism which ensures the components do not move from their desired location which allows for easier attachment of the components.
