Instrumentation and method for mounting a surgical navigation reference device to a patient
First Claim
1. A method of mounting a number of surgical navigation reference devices to a patient for performing an image-guided surgical procedure adjacent the patient'"'"'s hip joint, comprising:
- providing first and second bone anchors, the bone anchors having respective longitudinal axes, the first bone anchor having a first coupling member, and the second bone anchor having a second coupling member, the first bone anchor having an adjustable stop member positioned prior to insertion of the first bone anchor into a patient, to establish an insertion distance for a bone-engaging portion of the first bone anchor;
anchoring the first bone anchor to a portion of the patient'"'"'s pelvic bone, said anchoring including inserting said first bone anchor through a cannula and into engagement with the pelvic bone, and rotating said first bone anchor while maintaining the stop member stationary with respect to the first bone anchor to insert the first bone anchor into the pelvic bone until the stop member abuts a portion of said cannula to block further rotation of the first bone anchor;
coupling a first reference device to the first coupling member by moving a portion of the first reference device toward the axis of the first bone anchor to mount the first reference device in a substantially fixed position relative to the pelvic bone;
anchoring the second bone anchor to a portion of the patient'"'"'s femur;
coupling a second reference device to the second coupling member by moving a portion of the second reference device toward the axis of the second bone anchor to mount the second reference device in a substantially fixed position relative to the femur; and
performing an image-guided surgical procedure adjacent the patient'"'"'s hip joint.

Abstract
Instrumentation and methods are provided for mounting a surgical navigation reference frame to a patient. In one embodiment, 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 for anchoring to bone. The bone anchor cooperates with the cannula to form a mounting device adapted for coupling with the surgical navigation reference frame. In a further embodiment, an image-guided surgical procedure is performed at a location remote from the anchoring location. In a specific embodiment, a minimally invasive surgical procedure is performed adjacent the spinal column, with a reference frame anchored to the pelvic bone, and more specifically to the iliac region of the pelvic bone. In another specific embodiment, a minimally invasive surgical procedure is performed adjacent the hip joint, with a first reference frame anchored to the pelvic bone, and more specifically to the iliac region of the pelvic bone, and with a second reference frame anchored to the femur.
