摘要： A method for stabilizing bony structures comprises attaching a bone anchor with a first extender extending therefrom and having a receiving portion to a first vertebra. A second bone anchor is then attached to a second extender extending therefrom and having a receiving portion to a second vertebra. A connecting element is manipulated into a desired position relative to the first bone anchor and the second bone anchor and into a pathway defined in the second extender. A securing member is delivered through a passage in the first extender. The connecting element is secured in the receiving portion of the first bone anchor with the securing member. The second extender is manipulated so that it contacts the connecting element. The second vertebra is moved toward the connecting element while the second extender is contacting the connecting element until the connecting element is seated in the receiving portion of the second bone anchor. The connecting element is secured in the receiving portion of the second bone anchor. Finally, the first extender is disengaged from the first bone anchor and the second extender is disengaged from the second bone anchor.
