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.
