Instrumentation and method for mounting a surgical navigation reference device to a patient
First Claim
1. A method of mounting a surgical navigation reference device to a patient for performing an image-guided surgical procedure adjacent the patient'"'"'s spinal column, comprising:
- providing a bone anchor having a bone engaging portion;
anchoring the bone engaging portion of the bone anchor to bone at a location remote from the patient'"'"'s spinal column; and
coupling the reference device to the bone anchor to mount the reference device in a substantially fixed position relative to the patient'"'"'s spinal column.

Abstract
Instrumentation and methods are provided for mounting a surgical navigation reference frame to a patient for performing an image-guided surgical procedure on an anatomical component. In one embodiment of the invention, a trocar is positioned within a cannula to form an insertion device adapted for percutaneous introduction into the patient. A bone anchor having a bone engaging portion is inserted through the cannula and is anchored to bone. The bone anchor cooperates with the cannula to form a mounting device adapted for coupling with the surgical navigation reference frame. In one embodiment of the invention, an image-guided surgical procedure is performed at a location remote from the anchoring location. In a specific embodiment, an image-guided surgical procedure is performed adjacent the spinal column, with the bone engaging portion of the bone anchor anchored to the iliac region of the pelvic bone, and more specifically to the iliac crest of the pelvic bone.
