摘要： In one aspect, a bone plate system that includes a bone plate having a plurality of elongated through openings. The bone plate system includes a plurality of bone screws and a plurality of sliders in the elongated through openings of the bone plate that receive the bone screws. The bone plate system includes at least one resilient member for being configured to apply a biasing force to each of the sliders to urge the slider toward one end portion of a respective through opening. Further, the bone plate system includes at least one actuator having an interference position in which the actuator inhibits shifting of the sliders toward the one end portion of the through opening and a clearance position in which the actuator permits the at least one resilient member to urge the sliders and the bone screws received therein toward the one end portion of the through openings.

摘要： A bone plate system having a retainer for resisting back-out of a bone anchor from a throughbore of a bone plate is provided. In one aspect, a bone plate system having a resilient retainer disposed in a bone plate throughbore with a pair of elongate arm portions of the resilient retainer extending along opposite sides of the throughbore. In another aspect, a bone plate system having a resilient retainer with a pair of elongate interference portions completely exposed in the throughbore and spaced from each other across the throughbore to retain a head of a bone anchor received in the throughbore. In addition, a bone plate system having a resilient retainer with a pair of opposite end portions disposed within a groove of a throughbore wall such that a bone anchor may be inserted into the throughbore without contacting either of the opposite end portions of the retainer.

摘要： A multi-stage minimally invasive surgical procedure and associated instruments are disclosed. First, the surgical site is prepared. After preparation, the bone screws or anchors are attached to the bone. Subsequent to insertion of the screws, a rod or connecting member is positioned within the yoke portion of the bone screw. Caps are then placed in a pre-lock position within the yokes. The bone screws may be compressed together or distracted along the rod or connecting member, thereby setting the final spacing of the bones or bone segments. Finally the caps are moved to a final lock position to fix the screws to the rod or connecting member to maintain the bones in position relative to each other.

摘要： An expandable interbody device for implantation within an intervertebral space is provided, together with methods and tools for use therewith. The interbody devices of the present invention include upper and lower bearing members configured to expand via an expansion mechanism configured to allow the insertion of osteoconductive materials and other structures into the interior of the interbody device before and after implantation, and before and after expansion of the interbody device. The insertion tool is configured expand the interbody device and to allow insertion of materials into the interbody device through a protected pathway.

摘要： Instruments are provided for shifting elongate members, such as spinal rods, with respect to coupling members of spinal fixation systems. The instruments include a low friction drive mechanism having one or more rolling elements that ride along a helical groove or track in order to transform rotational movement of a drive member into linear shifting of a reducer member that shifts the elongate member. A one-way locking mechanism may be provided to selectively prevent unwanted counter-rotation of the low friction drive mechanism. The one-way locking mechanism may include annular ratchet teeth arranged on the exterior of the drive member and a ratchet pawl located adjacent to the teeth and selectively engageable therewith.

摘要： Disclosed are cement products, methods of forming cement using the cement product, and methods of using the cement product in orthopedic and dental applications. Generally, the disclosed cement product includes a first component and a second component. The first component comprises a polymerizable resin comprising ethylenic unsaturated double bond, a suitable glycidyl group and/or a suitable isocyanate group. The second component includes a compound comprising more than one type of amine selected from the group consisting of primary amine, secondary amines, tertiary amines and quaternary amines. Alternatively, the second component includes a compound comprising a suitable mercapto (SH—) group, a hindered amine or a dimethylthiotoluenediamine (DMTDA). Optionally, the cement product includes a filler and/or a bioactive component to promote bone formation.
