Abstract
The invention includes a method of determining a surgical patient's pelvic position and inputting that position into a computer via a tracking system, suitable for use in navigating partial or total hip replacement surgery. The patient is first aligned with anatomical reference points in relation to corresponding locating features on a patient positioner. The positions of index features on the patient positioner are then acquired via a tracking system. Based on the positions of the index features and their known relationship to the locating features, the locations of the anatomical reference features are calculated and a pelvic plane is defined therefrom. The invention also includes a surgical tool for mounting a trackable target to a human bone, suitable for fixation to a human femur. This tool includes a removable bone clamp and a releasable coupling member, integrated with said removable bone clamp.
