Patent number: 8696708Abstract: A facet interference screw (10) for insertion between the facet joints of adjacent superior and inferior vertebrae includes an externally threaded shaft portion and a head. The facet interference screw is preferably split into first (20) and second (30) components, each including an outer, semicircular externally threaded surface (22, 32) so that when coupled together the semicircular externally threaded surfaces form the externally threaded shaft portion.
