Abstract: An occipital plate may include a central section, a pair of angled sections, and attachment assemblies comprising slide members configured to move along slots in the angled sections, and posts coupled to the slide members. Each post has a first and second cross dimensions. The first cross dimension of each post is less than a first cross dimension of a slide member. The second cross dimension of each post is approximately equal to a second cross dimension of a slide member. Rods may be coupled to the occipital plate at a variety of angles with respect to a midline of the plate. The angular adjustability may accommodate any misalignments in the rods. Further, the position of the attachment assemblies relative to the midline is adjustable to thereby provide for medial-lateral adjustability when attaching the rods to the occipital plate as part of an occipito-cervico-thoracic construct.

Abstract: An expandable surgical site access system and method for using the expandable surgical site access system to perform minimally invasive, percutaneous surgeries to access the spine or other bone structures, organs, or locations of the body is disclosed. In one embodiment, the surgical site access system includes an elongated, expandable stent that is particularly adapted to be deployed in a body during a surgical procedure to provide access to a surgical site within the body. The stent defines a working channel through the body from a point of entry to the surgical site.

Abstract: An occipital plate for use in an occipito-cervico-thoracic (OCT) construct is mounted to a patient's occipital bone. The occipital plate includes an elongate central section aligned with a midline of the base and a pair of angled sections that project away from the central section and include attachment assemblies for securing a rod to the occipital plate. The attachment assemblies have multi-adjustability features. At least a portion of the attachment assemblies is rotatable with respect to the base so that the rods may be coupled to the occipital plate at a variety of angles with respect to the midline. The angular adjustability may accommodate any misalignments in the rods. Additionally, the position of the attachment assemblies relative to the midline of the occipital plate is adjustable to thereby provide for medial-lateral adjustability when attaching the rods to the occipital plate as part of the OCT construct.

Abstract: An installation system for installing a vertebral stabilization system. The system includes an implant guide and an insert. The implant guide includes a handle and a shaft extending from the handle. The distal end of the shaft is configured for engagement with a head portion of a vertebral anchor. The shaft has flexibility characteristics allowing the shaft to flexibly bend between a first configuration and a second configuration. The insert is slidably disposed along the shaft of the implant guide. The insert inhibits the shaft from bending from the second configuration to the first configuration.

Abstract: A method for securing a graft to a bone includes forming a tunnel in the bone, positioning the graft in the tunnel, and securing the graft in the tunnel with an anchor. The method also includes attaching a distal end of an elongated anchor sleeve to a proximal end of the anchor and inserting a pre-compressed harvested bone material having a cruciate cross-section through the anchor sleeve into to a bore defined in the anchor. The bore has a mating cruciate cross-section. The method also includes removing the anchor sleeve after inserting the bone material into the anchor.

Abstract: A polyaxial body is selectively removable from a pedicle screw in a spinal fixation system without disruption of the screw's placement in the patient's spine. The polyaxial body according to various embodiments of this invention may be locked relative to the screw head and coupled to the spine rod without deformation of the screw or body components while still allowing for subsequent removal of the body from the screw head. The head of the pedicle screw is threadably engaged with a retainer ring on the polyaxial body thereby permitting selective removal of the body from the screw head without disrupting the placement of the screw in the spine. This allows for the pedicle screw to remain in the spine as the fixation system is adjusted as required by the surgeon for subsequent and reliable reanimation.

Abstract: A fixation device for securing tissue to a bone. The fixation device includes an anchor having a hollow body defining a longitudinal passage, and a plug configured to be received in at least a portion of the passage. The body comprises a cylindrical portion and a tapered tip portion. The cylindrical portion comprises a plurality of thin-walled window covers such that after implantation the window covers are resorbed first relative to other portions of the cylindrical portion for defining a plurality of apertures on the cylindrical portion.

Abstract: A system and method to assist in securing a soft tissue replacement in a bone tunnel includes an expandable member having an opening and an expandable portion. A delivery structure includes a connection portion selectively coupled to the opening of the expandable member. The delivery structure is adapted to inject a flowable medium into the expandable member thereby expanding the expandable portion and urging the soft tissue replacement into a bone surface defining the bone tunnel.

Abstract: A nucleus replacement prosthesis for a nucleus of an intervertebral disc. The nucleus replacement prosthesis includes an elastic porous construct having a plurality of interconnected pores. The porous construct may be formed of a non-hydrogel material. The porous construct is compressible by the application of an applied compressive force from an enlarged state to a smaller compressed state. The porous construct is predisposed to assume the enlarged state in the absence of the applied compressive force without hydration of the porous construct. A substance may be located in the interconnected pores of the porous construct.

Abstract: An occipital plate for use in an occipito-cervico-thoracic (OCT) construct is mounted to a patient's occipital bone. The occipital plate includes an elongate base plate oriented with a midline of the base plate longitudinal on the occipital bone. A pair of lateral sections project in opposite directions from the central section and include attachment assemblies for securing a rod to the occipital plate. The position of the attachment assembly relative to the midline of the occipital plate is adjustable to thereby provide for medial-lateral adjustability. In specific embodiments, the attachment assemblies include a slide member which mates with the lateral section of the occipital plate in a dove-tail joint configuration and a set screw is threadably engaged with the slide member to secure the slide member relative to the midline of the occipital plate and the appropriate spacing and geometry for the specific patient. The set screw also secures a cam, which fixes the rod to the occipital plate.
