Title:
METHOD AND SURGICAL NAVIGATION SYSTEM FOR CREATING A RECESS TO RECEIVE AN ACETABULUM
Document Type and Number:
WIPO Patent Application WO2006133806
Kind Code:
A8
Abstract:
The invention relates to a method and a navigation system for creating a recess to receive an acetabulum in a navigated pelvic bone with the aid of a navigated tool. To help the operating surgeon determine the position of the receiving recess, the invention proposes that a navigated scanning instrument be used to locate the tear-drop point on the pelvic bone, that these position data and the plane of the pelvic inlet be used to determine a tear-drop plane that lies perpendicular to the latter plane and extends parallel to a line connecting the two anterior superior iliac spines and through the scanned tear-drop point, that a reference point be determined at a defined height above the tear-drop plane and in a defined position in the anterior-posterior direction and at a defined distance from the external aspect of the pelvic bone in the lateral-medial direction, and that the tool be worked into the pelvic bone in a desired direction relative to the reference point until a defined position of the tool relative to the reference point is reached.
