Percutaneous registration apparatus and method for use in computer-assisted surgical navigation
First Claim
1. A method of positioning an implant in an anatomy, including a first implant portion and a second implant portion with a surgical navigation system, comprising:
- positioning the first implant portion through an opening in a soft tissue of the anatomy;
tracking a position of the first implant portion;
interconnecting an implant inserter with the second implant portion;
determining a location of the second implant portion; and
moving the second implant portion relative to the first implant portion via determining a location of the second implant portion.

Abstract
An apparatus and procedures for percutaneous placement of surgical implants and instruments such as, for example, screws, rods, wires and plates into various body parts using image guided surgery. An apparatus for use with a surgical navigation system, an attaching device rigidly connected to a body part, such as the spinous process of a vertebrae, with an identification superstructure rigidly but removably connected to the attaching device. This identification superstructure, for example, is a reference arc and fiducial array which accomplishes the function of identifying the location of the superstructure, and, therefore, the body part to which it is fixed, during imaging by CAT scan or MRI, and later during medical procedures.

19. A method of performing a spinal procedure in an anatomy with a surgical navigation system, comprising:
-
positioning a first screw implant in a vertebrae percutaneously through an opening in a soft tissue of the anatomy;
tracking a position of the first screw implant;
orientating the first screw implant in a selected orientation at least in part via tracking the position of the first screw implant;
interconnecting an implant inserter with a rod;
determining a position of a portion of the rod; and
moving the rod relative to the first screw implant via determining a location of the rod to interconnect the screw with rod. - View Dependent Claims (20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53)
