A localization device display method and apparatus for recording positional parameters associated with a tool being navigated with the localization device. The localization device monitors the position of a tool and automatically records positional parameters associated with the tool when the positional parameters conform to an area of interest and the tool is stable.

Recording localization device tool positional parameters

A system and method for creating a cavity to receive an acetabulum in a pelvic bone with the aid of a navigated tool are provided. A tear-drop point on a pelvic bone is located by means of a scanning instrument. A tear-drop plane is determined from position data of the tear-drop point and the plane of the pelvic inlet. The tear-drop plane lies perpendicular to the plane of the pelvic inlet, extends parallel to a line connecting the two anterior superior iliac spines, and runs through the tear-drop point. A reference point is determined which is at a defined height above the tear-drop plane, in a defined position in an anterior-posterior direction, and at a defined spacing from an outer surface of the pelvic bone in a lateral-medial direction. A tool is worked into the pelvic bone in a desired direction relative to the reference point.

Method and surgical navigation system for creating a recess to receive an acetabulum

A method and apparatus for cross checking points palpated with a localization device. Points corresponding to the palpated points are obtained from a preoperative image of an object such as an X-Ray of a tibia bone. During a surgical procedure, the accuracy of palpated points are determined based on the palpated points and corresponding points obtained from the preoperative image. If a palpated point is inaccurate, an indicator is generated to indicate the inaccuracy of the palpated point.

Localization device cross check

An apparatus for positioning the cutting angle of a bone cutting guide, wherein the bone is preferably a tibia and/or a femur, which includes a first fastener to fasten the positioning apparatus to the bone such that the whole of the apparatus and the fastener of the cutting guide can rotate relative to the fastening axis, and a second fastener to fasten the positioning apparatus at a second fastening location onto the bone different from the first fastening location, so as to fix apparatus at a required position within the rotation relative to the first fastening axis.
