Abstract
A monopedicular targeting system for posterior spinal surgery includes a first joint component, a fastener for affixing the first joint component to a single pedicle, a positioning arm having a second joint component for mating with the first joint component to form a first joint having three rotational degrees of freedom, and a connector for coupling the spinal surgery device to the positioning arm. The connector has a third joint component that mates with a fourth joint component of a spinal surgery device to form a second joint having three rotational degrees of freedom. A monopedicular targeting method for posterior spinal surgery includes affixing a fastener to a single pedicle and adjusting three translational degrees of freedom and three rotational degrees of freedom of a posterior spinal surgery device with respect to a pedicle of a vertebra by manipulating joints of a manipulator connecting the spinal surgery device to the fastener.
