Abstract: A spinal screw assembly is provided. The assembly may be provided with a screw and a movable head in which angulation of the screw relative to the movable head is constrained so that angulation within limits is allowed in one plane but lesser or no angulation is allowed in another plane. Methods to assemble the disclosed apparatus are also disclosed.

Abstract: An anterior cervical plate is disclosed, along with threaded fasteners for securing the plate to vertebrae or other osseous material. The cervical plate has several pockets or apertures, preferably at least four, to receive a corresponding number of the fasteners. The pockets have spherical surfaces, and the fasteners have heads with similarly sized spherical surfaces, which when engaged permit each of the fasteners to be oriented at a variety of projection angles with respect to the plate. In connection with each pocket, the cervical plate incorporates a fastener retaining feature. The feature can take the form of a cantilevered tab or a beam supported at its opposite ends, in each case plastically deformable between an open position for admitting the fastener and a closed position for preventing retraction.

Abstract: The invention is directed to a retainer (10, 12, 70) for securing a sponge (16) at the point of entry for an orthopaedic elongate member (14). The retainer (10, 12, 70) is removably attachable to the elongate member (14) adjacent the sponge. The retainer, in one embodiment, includes a body (22) having a bottom (24) and a side (26), with the side (26) being disposed adjacent to the bottom (24). The body (22) further includes an opening (34) associated with each of the bottom (24) and the side (26). The opening (34) is configured for receiving the elongate member (14) therein. A clamp (40) is movably attached to the body (22) and engageable with the elongate member (14) for retaining the elongate member (14) within the opening (34). A resilient member (50) is integral or engaged with the clamp (40) for biasing the clamp (40) into engagement with the elongate member (14).
