1. A method comprising:

  • engaging a bone anchor to a location on a vertebral body when the vertebral body is in a first orientation;

    coupling the bone anchor with a correction tool;

    manipulating the correction tool to move the vertebral body toward a second orientation with the bone anchor;

    electrically monitoring the bone anchor with a nerve monitoring system that provides an electrical signal that travels through the correction tool to the bone anchor to detect interference between a neural element and the bone anchor while the vertebral body is moved toward the second orientation; and

    retaining the vertebral body in the second orientation by coupling a connecting element to the bone anchor and an implant engaged to a second vertebral body, the connecting element being spaced apart from the implant while the correction tool is manipulated to move the vertebral body.
