Abstract
Methods and instruments are provided for connecting a rod extending along a patient's spinal column to a misaligned vertebra. The method comprises implanting a bone anchor in the misaligned vertebra, attaching an approximating device to the implanted bone anchor and rod, approximating the vertebra toward the rod using the approximating device, and connecting the rod to the bone anchor on the approximated vertebra. In certain embodiments the approximating device may include a winch mechanism. In other embodiments the approximating device is a cannula used in conjunction with a guide system.
