  • Patent number: 8147527
    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.

  • Patent number: 8142434
    Abstract: A bone plate mounted on a bone. The bone plate has at least one opening for receiving a flush mounted cam. A through-bore passes from a side surface to opposing side surface of the bone plate. The through-bore has a diameter sized to allow insertion of a cable. A portion of the through-bore intersects with a peripheral portion of the opening. A second opening also passes from the side surface to opposing side surface. A cable may be inserted in the second opening, wrapped around the bone and its free end inserted in the through-bore. The cable may be tightened around the bone. The flush mounted cam can be rotated in place. Rotation of the cam results in the cam surface squeezing the cable between concave cam surface and walls of the opening, thereby locking the cable in the tightened state.

  • Patent number: 8062294
    Abstract: An orthopaedic implant provides a simple yet effective retention system requiring no additional components beyond the implant and the associated fastener(s). A plurality of anti-rotation protrusions on the fastener or screw head that match recesses in the implant. The protrusions engage the recesses to prevent the fastener from reversing direction, thereby assuring that the associated fastener does not backout during normal motion of the spine and other anatomical structures. A land on the fastener screw thread assures the fastener will not disengage from the implant should it strip out of the bone. Preventing the fastener from backing out assures it will not detach from the implant or staple, assuring that the implant will remain in place until all fasteners in the system have catastrophically failed. The anti-backout features of the invention provide feedback as they engage, allowing the surgeon to move quickly when placing a fastener without the concern for inadvertent over-tightening.

  • Patent number: 8016863
    Abstract: A plate of biocompatible material is provided having curvature in two planes such that it conforms to the curvature of the L5 vertebral body and to the patient's lordotic curve. Holes are provided receiving screws for anchorage in the vertebral body and sacrum. A flange or foot portion on the plate provides a wider base end area for support in the L5-S1 interspace. The foot portion is also arranged for appropriate entry angle of screws into the sacrum such as to improve anchorage in the sacrum. Anti-backout and low profile features are incorporated. The anterior lumbar plate is situated to maintain the anterior interbody bone graft in compression by resisting tensile forces during extension.

    Abstract: Ceramic precursor compositions and chemically bonded ceramic (CBC) materials, especially Ca-based, and a composite biomaterial suitable for orthopaedic applications. The CBC-system includes a binding phase (chemical cement) and additional phases with specified chemistry imparting to the biomaterial the ability of initial strength followed by interaction with the body tissue including body liquid, to form a resorbable or partly resorbable biomaterial. The ceramic precursor composition includes at least one silicate with Ca as the main cation with a resorption rate less or equal to that of the bone in-growth rate. The silicate will form the binding phase of the cured material. Implants and surface coated devices are also disclosed. The cured material exhibits a compressive strength exceeding 100 MPa.

  • Patent number: 7963980
    Abstract: An anti-subsidence, anti-translocation, fusion compression cervical plate system with interface visualization, drill guide and temporary pin is provided. In one embodiment the invention provides a vertebral plate for minimizing the ability of an inter-body cage, filled with bone (or BMP-soaked sponges, etc.), to telescope into the vertebral body and to minimize failure due to cages that telescope into adjacent vertebral bodies on a delayed basis after surgery, as well as creation of reverse lordosis due to such telescoping. Another embodiment provides method to reduce the gap between the inter-body cage and the vertebral body end plate intra-operatively using compression from the plate caused by an offset between the screw bores on the plate and the drill holes, as established with an asymmetric drill guide.

  • Patent number: 7963979
    Abstract: A provisional bone plate formed of an implantable plastic and having a length corresponding to the longest bone plate in a particular family of bone plates. The provisional bone plate includes a head contoured to match the head of a particular bone as well as a shaft for placement adjacent the bone shaft. The provisional bone plate includes a plurality of circumferential notches surrounding the elongate body or shaft of the bone plate. The circumferential notches are substantially transverse to a longitudinal axis of the bone plate and define frangible portions of the bone plate which can be removed from the distal end thereof to alter the length of the provisional periarticular bone plate to correspond to the length of the various bone plates in a family of bone plates. The provisional bone plate is constructed of a biologically suitable plastic, is radiographic, and melts at a temperature less than 200° Fahrenheit.
