Abstract:
1. A spinal instrumentation kit, comprising: a first bone anchor configured to be implanted in a first vertebra; a first elongate body configured to couple to the first bone anchor; a second bone anchor configured to be implanted in a second vertebra; a second elongate body configured to couple to the second bone anchor; and a connector having a ring-shaped member and a U-shaped extension, the ring-shaped member being configured to slidably receive one of the first and second elongate bodies and to prevent the one of the first and second elongate bodies from rotating relative to the ring-shaped member, and the U-shaped extension having first and second arms each having a free end, the free ends forming an open end of the U-shaped extension that faces away from the ring-shaped member, the U-shaped extension allowing the other one of the first and second elongate bodies to rotate and pivot freely toward and away from the ring-shaped member; wherein when the first and second bone anchors are implanted in first and second vertebrae and the first and second elongate bodies are coupled to the first and second bone anchors, the connector is configured to function as a fulcrum to allow pivotal movement of the first and second elongate bodies about the fulcrum to thereby compress or distract the first and second vertebrae relative to one another.
