  • Publication number: 20170224502
    Abstract: A spinal interbody implant has a bone screw retention mechanism that prohibits bone screws from backing out after the bone screws are installed. A bone screw retention plate is received in a plate retention area of the implant to provide a barrier that keeps the installed bone screws from backing out of their bone screw pocket. The bone screw retention mechanism consists of a retention plate and a configured plate retention area in a face of the implant body. Retention plate fasteners may be used to retain the configured plate. In one form, the bone screw retention mechanism consists of a retention plate, a configured plate retention area in a face of the implant body, and a retention plate bolt. In another form, the bone screw retention mechanism consists of a retention plate, a configured plate retention area in a face of the implant body, and a retention plate bolt.

  • Patent number: 9005249
    Abstract: A spinal rod connector assembly for use with a vertebral bone screw has an articulating clamp for 1) fixing an orientation of the spinal rod connector assembly relative to and on the vertebral bone screw, and 2) attaching a separate spinal rod onto the spinal rod connector assembly in concert with one another. The articulating clamp resides in a body of the spinal rod connector assembly and transfers a received downward force laterally to a spinal rod component of the spinal rod connector assembly which is configured to abut the spinal rod and hold the spinal rod between itself and a spinal rod holder of the spinal rod connector assembly. The articulating clamp thus improves the force transfer efficacy of the system.
