Abstract
A clamp device includes multiple claws for collectively gripping a vertebra, particularly over a pars interarticularis. At least one of the claws is movable relative to a body of the clamp device. The movable claw includes an elongate tab received within a track extending within the body. The body or the tab includes a threaded hole within which set screws may be received for immobilizing the movable claw relative to the body. The clamp device also includes an array of rod clamps. The rod clamps are supported by the body, and more directly by a bar supported by the body. The bar is releasably connectable to the body, and the rod clamps are pivotably connectable to the bar.
