  • Patent number: 9918748
    Abstract: A rod connector for joining a first rod and a second rod includes bore holes that are offset and/or non-parallel to each other. The rod connector provides an offset or non-parallel connection between the rods that allows for the rods to match the contour of a patient's body without requiring bending of the rods. The rod connector may include a first bore hole for receiving the first spinal rod and a second bore hole for receiving the second spinal rod that is adjustable relative to the first bore hole to adjust the position and/or orientation of the second spinal rod relative to the first spinal rod. The rod connector may comprise a first housing component defining the first bore hole and a second housing component that is movable relative to the first housing component and defining the second bore hole.

  • Patent number: 8728080
    Abstract: A spinal fixation plate that is adapted to be implanted in a variety of positions in the occiput is provided. In general, the plate has a substantially planar configuration and it includes a mid-line or central portion having several thru-bores formed therein, and first and second opposed branch portions that extend from the central portion and that also include at least one thru-bore formed therein. The configuration of the branch portions relative to the central portion, as well as the position of the mid-line thru-bores formed in the central portion in relation to the thru-bore(s) formed in each branch portion, allow the spinal fixation plate to be implanted in a variety of positions in the occiput, thus allowing the optimal implant site to be selected.

  • Patent number: 8672984
    Abstract: A retention system for maintaining a screw to a vertebral plate is described herein. One or more screws extend through apertures within the vertebral plate. A cavity is positioned adjacent to and overlaps into the aperture. A ring is positioned within the cavity and held in position by a cap. The cap attaches to the plate to prevent removal of the ring. The ring is deflectable between a first shape to allow the screw to be inserted and removed from the aperture, and a second shape to prevent screw back-out from the aperture.

  • Publication number: 20050228326
    Abstract: A spinal fixation system comprising at least two bone anchors, a rod connecting the bone anchors and a connecting plate extending from a proximal surface of at least one of the bone anchors. A method of fixing vertebrae relative to each other comprising the steps of: implanting bone anchors in two adjacent vertebrae, each bone anchor having a rod receiving portion; placing a rod in the rod receiving portions, thereby connecting the bone anchors; threadably engaging set screws in the rod receiving portions of at least a portion of the bone anchors, thereby fixing the rod to the bone anchors; mating one end of a connecting plate to a proximal bearing surface of at least a portion of the bone anchors; and engaging a cap with at least a portion of the set screws, thereby fixing the connecting plate to the bone anchors.
