Abstract
A surgical reference device for use with a computer-assisted surgery system comprises an engaging member adapted to engage directly on soft tissue of a body part such that substantially no relative movement is possible between the engaging member and a bone element of the body part. A trackable member is attached to the engaging member and comprises a detectable element for being located and tracked in three-dimensional space by the computer-assisted surgery system to measure a position and an orientation of the trackable member in time, whereby the bone element is tracked as a function of the position and orientation of the trackable member. A method for tracking a position and an orientation of a bone element using a computer-assisted surgery system is also provided.
