<p>Spinal implants with features for anchorage in or onto bone or to connectors, have a body (31) with an upwardly opening channel (32) receiving a spinal rod therein. The channel has sidewalls with a curved slot (36, 37) in each of the sidewalls. A cap (46) is mounted on the implant body and has a central portion received in the channel and has tongues (48) at each side of the central portion, the tongues being received in the curved slots in the sidewalls. A set screw (57) threaded into the cap engages the spinal rod and clamps the rod between the body and the set screw and fixes the cap to the body. The curved slots enable installation of the cap in minimal space measured lengthwise of the rod. Each implant body has an integral bone screw (Fig. 2) or bone hook (18, Fig. 15), or lateral connector rod (87, Fig. 18) or parallel spinal rod receiving body (99, Fig. 20, 21) thereon.</p> |
