  • Patent number: 8920508
    Abstract: A joint prosthesis system, specifically a shoulder prosthesis, for shoulder replacement, revision and repair. The implants provide fixation into the best bone available to a surgeon. The implants are used in a superior-inferior and anterior-posterior construct forming a type of cross or X-shape. The implants allow for interchangeability of the articulating component as well as rotational orientation. The systems will allow for augments to accommodate bone loss. The implants may allow for additional security using screws or anchors inserted into the scapula.

  • Publication number: 20140135837
    Abstract: A posterior spinal fusion system may include pedicle screws and one or more segments designed to be attached to the implanted pedicle screws via nuts to fuse spinal motion segments in a modular fashion. The pedicle screws may have semispherical receiving surfaces, and each segment may have mounting portions at both ends, with corresponding semispherical engagement surfaces. The nuts may also have semispherical surfaces. The semispherical surfaces permit polyaxial adjustment of the relative orientations of the segments and pedicle screws. Each mounting portion may have a passageway therethrough to receive the proximal end of the corresponding pedicle screw; each passageway may intersect the edge of the corresponding engagement surface to facilitate percutaneous placement. Such placement may be carried out through cannulae to provide a minimally invasive (MIS) implantation procedure.

  • Patent number: 8702796
    Abstract: A system for single tunnel, double bundle anterior cruciate ligament reconstruction includes implant constructs and instruments. The implant constructs provide a combination of cortical fixation and bone tunnel aperture fixation. The implant constructs separate a graft into distinct bundles. The instruments are used to prepare shaped bone tunnels to receive the implant constructs and graft bundles. Methods for reconstructing the antero-medial and postero-lateral bundles of the anterior cruciate ligament may rely on single femoral and tibial tunnels and a single strand of graft.

  • Publication number: 20140066931
    Abstract: External fixation systems, and methods for immobilizing joints or fractured bones. An external fixation system may include one or more clamp assemblies connected to one or more rod assemblies at polyaxial joints. Each rod assembly may be length adjustable, and may include a one-way locking mechanism to provisionally lock the length of the rod assembly, and additional locking mechanisms to permanently lock the length of the rod assembly. The system may be deployed pre-assembled as a unit to immobilize a joint or fracture. Another external fixation system further includes a spanning member extending transverse to the rod assemblies. Two or more external fixation systems may be deployed in a stacked configuration on one set of bone pins to immobilize two joints and/or fractures. The systems may be provided in kits including guiding instrumentation, bone pins and pin clamping assemblies for connecting the bone pins to the external fixation systems.

  • Patent number: 8636780
    Abstract: A system for restoring articular cartilage has a cover, an anchor, and a tether that cooperate to retain graft tissue with respect to a graft site. The cover is attached to the anchor via the tether. The tether passes through a tunnel through a bone to which the articular cartilage is attached. The tunnel may be blind or may extend through the bone. The anchor is retained within the tunnel such that tension in the tether keeps the cover in place over the tissue graft. The anchor may receive the tether such that the tether can only pass through the anchor along one direction. Thus, tension applied to the tether between the anchor and the tissue graft is automatically maintained by the anchor. After passing through the anchor, the tether may exit the tunnel through the graft site, or through the opposite side of the bone.

  • Publication number: 20140020690
    Abstract: A limb positioner apparatus includes a stabilizing plate and a movable positioning plate for arrangement about a joint or fracture. The movable plate is movable with respect to the stabilizing plate about three mutually perpendicular planes which intersect at a point corresponding to a center of rotation of the joint or fracture. The positioning plate may also be movable with respect to the stabilizing plate along at least one linear direction. At least some of the available degrees of freedom are selectively lockable. The apparatus is illustrated in the context of the foot and ankle. Methods of use are disclosed.

  • Patent number: 8628579
    Abstract: A knee prosthesis including femoral and tibial implants, a tibial insert and a cam post assembly. The femoral implant is secured to a femur and has a cam feature and condyles. The tibial implant is secured to a tibia. The tibial insert has articulating surfaces that match the contours of the condyles of the femoral implant, and may have a medial boss that aligns with the tibial implant to provide rotation about a medially displaced rotation axis. A cam post is secured to the tibial implant and passes through a channel of the tibial insert. A motion limiting structure provides limits to motion between the tibial insert and the tibial baseplate. The cam post assembly interacts with the femoral implant cam feature and allows more anatomically correct rollback and femoral external rotation during knee flexion, and varus/valgus support to the femur.

  • Patent number: 8628576
    Abstract: Systems for interbody fusion of adjacent bone portions may include an expanding implant and related instruments. An expanding implant may be formed as a linkage which is movable between a compact configuration and an expanded configuration. A shaft of the implant may increase and decrease in length to move between the compact and expanded configurations, and an implant width perpendicular to the length may be increased in the expanded configuration. The implant width may increase more in a first direction than a second direction opposite the first direction. An inserter instrument may releasably grasp the spacer and transform the implant between the compact and expanded configurations.
