摘要： An intervertebral joint assembly includes an upper support and a lower support, each of which has two or more components. The upper and lower support components are arranged in situ to form the upper and lower supports, respectively. By arranging the supports in situ, the supports can be introduced from the back of the patient, for example with an arthroscope. Each of the upper and lower supports has a surface adapted to engage a vertebra and a surface adapted to engage the other support or an intermediate member to form an articulate joint which articulates the joint assembly. In some embodiments, the components of the upper and lower supports are assembled in situ, for example with pivoting, telescoping or bending, to form the upper and lower supports, respectively. The supports can be attached to vertebrae with pedicles screws, and/or other anchors attached to the supports.

摘要： A prosthetic disc for insertion between adjacent vertebrae includes upper and lower plates and a core having upper and lower curved surfaces disposed between the plates. At least one of the plates and/or the core includes a resilient material for absorbing shock or other forces applied by vertebrae. Optionally, resilient support members may be disposed within the resilient material to connect two portions of a plate or the core. Such support members may be springs, cylinders, wires or other resilient structures. The resilient material is held within the core or plate(s) via a surrounding retaining structure, such as a membrane. The resilient material disposed in one or more components of the prosthetic disc provides for shock absorption.

摘要： A compliant intervertebral spacer according to the present invention replaces a damage intervertebral disc and functions to maintain disc height and prevent subsidence with a large surface area while substantially reducing patient recovery time. The compliant intervertebral spacer for spanning a space formed by upon removal of an intervertebral disc includes two end plates sized and shaped to fit within an intervertebral space and a compliant connector interconnecting the inner surfaces of the two end plates in a manner which limits motion between the plates to less than a total of 5 degrees of motion in any direction. The intervertebral spacer is configured to permanently maintain the disc space between the two adjacent discs without the use of bridging bone.

摘要： An implanted intervertebral prosthesis includes first and second components adapted to attach to a first vertebra and a second vertebra, respectively, that define an intervertebral space. The prosthesis includes a first anchor structure on the first component adapted to enter a grove formed in the first vertebra, and a second anchor structure on the second component adapted to enter a grove formed in the second vertebra. The first anchor structure is offset from the second anchor structure to provide separation of the grooves to preserve vertebral thickness and avoid vertebral splitting. The offset anchor structures can be symmetrically disposed about a midline of the prosthesis or asymmetrically disposed about the midline. In some embodiments, the offset anchor structures comprise elongate anchors shaped as fins or keels. In other embodiments, the offset anchor structures comprise rows of pillars disposed in rows.

摘要： A method for inserting an intervertebral disc prosthesis into a space between two vertebrae involves inserting the prosthesis partway into the space under constraint to prevent endplates of the prosthesis from articulating, releasing the prosthesis from constraint, and inserting the unconstrained prosthesis farther into the space. In some embodiments, the method involves grasping the prosthesis with a grasping device to insert the prosthesis partway under constraint, loosing the grasping device to release the prosthesis from constraint, and pushing the prosthesis farther into the disc space using the grasping device and/or one or more separate pusher devices. A system includes a grasping device, at least one separate pushing device, and optionally a vertebral spreading device and/or a vertebral midline indicator device.

摘要： A prosthetic disc for insertion between adjacent vertebrae includes a core having upper and lower curved surfaces and upper and lower plates. At least one of the curved surfaces of the core is metallic, and in some embodiments the entire core is metallic. Each plate has an outer surface which engages a vertebra and a metallic inner curved surface which is shaped to slide over one of the curved surfaces of the core. In some embodiments, the center of rotation of the core is free to move relative to the upper and lower metallic plates. In some embodiments, one or more channels extend across one or both of the curved surfaces of the core for allowing passage of bodily fluid to promote lubrication between the core and at least one of the plates.

摘要： A prosthesis system comprises plates that can be positioned against vertebrae and a selected resilient core that can be positioned between the plates to allow the plates to articulate. The selected resilient core can be chosen from a plurality of cores in response to patient characteristics, such as age and/or intervertebral mobility, such that the prosthesis implanted in the patient is tailored to the needs of the patient. The plurality of cores may comprise cores with different resiliencies, and one of the cores can be selected such that the upper and lower plates articulate with the desired shock absorbing resiliency and/or maximum angle of inclination when the one selected core is positioned between the plates.
