A device for positioning a fiducial marker (160) on an anatomical structure includes a fiducial base (40) and a fixation member (60). The fiducial base (40) comprises a turn (44) and an extension (42) configured to position the fiducial marker (160) within the field of view of a tracking sensor (210). The fiducial marker (160) is positioned away from the anatomical structure. The fixation member (60) is configured to have a low profile and further configured to fix the fiducial base (40) to the anatomical structure. The fixation member (60) is fixed to the anatomical structure through a primary surgical incision and positioned on the anatomical structure such that the fixation member (60) is isolated from the surgical approach. The fiducial base (40) extends from the fixation member through the primary surgical incision. |
