  • Publication number: 20100042153
    Abstract: A posterior vertebral stabilizer has a resilient member such as a linear spring, which operates in tension and compression. The resilient member may be kept straight by a stabilization rod extending through the spring, or by a telescoping assembly that encases the resilient member. The ends of the stabilizer are attachable to pedicles of adjacent vertebrae so that the stabilizer adds stiffness to control flexion and extension of the vertebrae. Two such stabilizers may be used, and may be connected together by a crosslink designed to limit relative rotation of the stabilizers. Thus, the stabilizers may restrict axial rotation and lateral bending between the vertebrae, while permitting stiffened flexion and extension. Such stabilizers help provide the stiffness of a healthy intervertebral disc. In the event that fusion of the joint becomes necessary, a set screw or other component may be used to further restrict flexion and extension.

  • Patent number: 7628799
    Abstract: The invention is a rod to rod connector that can be used to interconnect two generally parallel spinal rods of a spinal rod and anchor system. The connector comprises a transverse rod and two pairs of clamping bodies, one for each spinal rod. Each pair connects one of the longitudinal spinal rods to the transverse rod in infinitely adjustable angular relationship. One of the two clamping bodies of each pair comprises a C-shaped channel for accepting the spinal rod. The channel is in communication with a slot that defines a hinge. A threaded screw hole passes transversely through the slot and permits a screw to squeeze the hinge, thereby causing the C-shaped channel to close around and clamp the rod. The second clamping body is similar to the first except that there is no slot or hinge and the screw hole preferably is not threaded, but includes a countersink for seating a chamfered screw head. Also, an angular portion of the screw hole intersects the C-shaped channel.
