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.
Claims19
A facet distraction prosthesis comprising:
- an array of facet distraction base elements, adjacent ones of said base elements being connected to each other by a set of connector elements located at said adjacent ones of said base elements;
- wherein said set of connector elements comprises 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 said 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, wherein each of said base elements comprises two male connectors that protrude from adjacent, perpendicular sides of said base element, and two female connectors that protrude from two other adjacent, perpendicular sides of said base element and each of said male connectors is parallel to a corresponding one of said female connectors.
(canceled)
A joint prosthesis comprising:
- an array of joint base elements, adjacent ones of said base elements being connected to each other by a set of connector elements located at said adjacent ones of said base elements;
- wherein said set of connector elements comprises 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 said 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 joint, wherein each of said base elements comprises two male connectors that protrude from adjacent, perpendicular sides of said base element, and two female connectors that protrude from two other adjacent, perpendicular sides of said base element and each of said male connectors is parallel to a corresponding one of said female connectors.
