Abstract
A surgical bone reference assembly is communicable with an image guided surgical system such that position and movement of a bone element are monitorable. A bone anchor member comprises a trackable member and teeth engageable with the bone element. The trackable member comprises a detectable element adapted to be located and tracked in three dimensional space by the image guided surgical system, thereby defining position and movement of the trackable member. A protective guide member is used with the bone anchor member such that the bone anchor member is insertable through soft tissue covering the bone element without causing significant damage thereto. The bone anchor member is engageable with the bone element, such that the teeth are forced into engagement with the bone element and the bone anchor member is fastenable to the bone element in a fixed relation thereto.
