Patent ID: 8180429

Claim:
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.
