  • Publication number: 20190167316
    Abstract: A facet distraction prosthesis includes an array of facet distraction base elements, connected to each other by a set of connector elements located at adjacent base elements. The set of connector elements includes a male connector having an at least partial cylindrical or spherical contour that is received in, and articulates with, an at least partial cylindrical or spherical recess of a female connector, so that adjacent ones of the base elements can bend in multiple degrees of freedom about different bending axes with respect to each other and adapt to a geometry of a facet joint.

  • Publication number: 20190151109
    Abstract: A facet distraction prosthesis (10, 30) includes an array of facet distraction base elements (12, 32) connected to each other by one or more connector elements (14, 34). A pair of diagonally adjacent base elements (12, 32) are connected to each other by a set of or more connector elements (14, 34) which intersects with another set of one or more connector elements (14, 34) that connects another pair of diagonally adjacent base elements (12, 32). The connector elements (14, 34) are flexible so that the base elements (12, 32) can flex with respect to each other and adapt to a geometry of a facet joint.

  • Patent number: 9622786
    Abstract: A spinal cage (80) including first and second spinal attachment members (82, 84) attachable to vertebrae (83, 85), the first and second spinal attachment members (82, 84) articulating with one another by means of an articulation joint (86, 88), characterized by a wedge element (90) arranged for wedging between the first and second spinal attachment members (82, 84), and an actuator (92) linked to the wedge element (90) for moving the wedge element (90) in a direction that wedges the wedge element (90) further in between the first and second spinal attachment members (82, 84) or further away from the first and second spinal attachment members (82, 84).

  • Patent number: 9427331
    Abstract: A spinal cage includes first and second spinal attachment members attachable to vertebrae, the first and second spinal attachment members articulating with one another by means of an articulation joint, and a wedge element arranged for wedging between the first and second spinal attachment members. An actuator is linked to the wedge element for moving the wedge element axially with respect to the first and second spinal attachment members. The actuator includes a threaded member adjacent the wedge element and a biasing device positioned between at least one of the first and second spinal attachment members and the wedge element. Upon turning of the threaded member, the wedge element is advanced with respect to the articulation joint so that the first and second spinal attachment members are tilted or parallel to each other. The biasing device applies a biasing force on the wedge element to move the wedge element axially.
