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.
L'invention concerne un ensemble d'articulation intervertébrale qui comprend un support supérieur et un support inférieur, chacun possédant un ou plusieurs composants. Les composants des supports supérieur et inférieur sont disposés in situ afin de former respectivement les supports supérieur et inférieur. En disposant les supports in situ, ceux-ci peuvent être introduits à travers le dos du patient, par exemple au moyen d'un arthroscope. Chacun des supports supérieur et inférieur possède une surface conçue pour se coupler à une vertèbre et une surface conçue pour se coupler à l'autre support ou à un élément intermédiaire en vue de former une articulation qui articule l'ensemble d'articulation. Dans certains modes de réalisation, les composants des supports supérieur et inférieur sont assemblés in situ, par exemple, par pivotement, télescopage ou flexion, afin de former respectivement les supports supérieur et inférieur. Ces supports peuvent être fixés aux vertèbres au moyen de vis de pédicule, et/ou d'autres pièces d'ancrages fixées aux supports.
