    摘要： A spinal disc replacement surgical instrument includes a first contacting member positionable along an endplate of a first vertebra and a second contacting member positionable along an endplate of second vertebra. The second contacting member is moveable relative to the first contacting member. A handle assembly is coupled to the first contacting member and the second contacting member. At least one actuating member is positioned between the first contacting member and the second contacting member. The at least one actuating member is moveable by the hand assembly from a first position, wherein the first and second contacting members include an unexpanded configuration relative to one another for insertion in the spinal cavity, to a second position providing expanded configuration relative to one another. The actuating member is configured to displace at least one of the first contacting member and the second contacting member away from each other to move the first contacting member and the second contacting member between the first position and the second position. The first contacting member has a first distal end and the second contacting member has a second distal end. The first end has a first end shape configured to conform to a shape of the first vertebra and the second end has a second end shape configured to conform to a shape of the second vertebra. The first end shape and the second end shape are different shapes.

    摘要： The present application is directed to devices and methods for attaching one or more elongated members to a posterior surface of a vertebral member. The devices may include a body with a first face that contacts the vertebral member and a second opposite face. A hook may extend outward from the first face to engage the vertebral member. The body may also include one or more receivers to receive the elongated members. An engagement member may be movably connected to the body. The engagement member may include a first section that contacts the body, and a second section that includes a second hook. The engagement member may be positioned relative to the body to adjust a distance between the first and second hooks to attach the body to the vertebral member. A fastener may secure the engagement member to the body at the desired position. The fastener may also attach the one or more elongated members to the body.

    摘要： A hand-held instrument, with a rotary power input to a camshaft, has cam and follower arrangement to provide a reciprocating shaft output. A cutter is provided on the output shaft. In one example, rotating cam percussion is transmitted to the cutter by engaging the cutter with the tissue to be cut, and pushing the instrument forward toward the cutter. In another example, rotating cam percussion is transmitted to the cutter by engaging the cutter with the tissue to be cut, and pulling the instrument back toward the user while maintaining engagement of the cutter with the tissue. In both examples, the cutter remains in idle condition until an axially directed load, forward in the one example, or backward on the other example, is placed on the cutter by moving the instrument forward or backward, respectively, while the camshaft is rotating. A distractor with frame is used to spread and maintain space between vertebral bodies, enabling entrance of the cutter.

    摘要： Systems and methods for stabilizing the spine are provided. For stabilizing the L5-S1 junction, the system includes a plate that has a generally triangular shape with an upper node and a pair of lower nodes. The upper node has a hole through the plate to receive a screw for passage into the L5 vertebra. The lower nodes each include a hole through the plate to receive screws for passage into the S1 vertebra. The system further includes a plate having a retaining element for preventing backout of screws inserted through the plate. Instruments and methods for attaching the plate to the spinal column are also provided.

    摘要： This invention relates to methods and instruments for performing a surgical procedure in a disc space between adjacent vertebrae. The instruments include a distractor and a cutting instrument. In one embodiment the distractor includes a body portion and a pair of flanges extending along opposite sides of the body portion such that a slot is formed between the flanges and the body portion. The cutting instrument is positionable over the body portion and into the slots of the distractor so that the flanges are positioned between the cutting instrument and the adjacent tissue.

    摘要： A plating system for stabilization of a bony segment includes a plate engageable to at least first and second bony elements. For spinal stabilization, the plate is attached at least to first and second vertebrae with at least one bone fastener in each vertebra. Retaining members are attachable to the plate to prevent the bone fasteners from backing out of the plate. One retaining member is a variable retaining member that allows the bone fasteners to toggle in the plate without interference. A second retaining member is a fixed retaining member that fixes the bone fasteners relative to the plate.
