Claim:
1. A method for tracking a bone with a gyroscope sensor unit secured to the bone, comprising: obtaining, by a processor of a system for tracking a bone, gyroscope readings for three axes of rotation during specific movements of the bone about a desired axis, the specific movements being reciprocating movements of rotation of the bone about the desired axis with the bone and the desired axis both being fixed in position in space, the bone having an elongated shape and the desired axis being a longitudinal axis of the elongated shape; summing, by the processor, at least part of the gyroscope readings; determining, the processor, an orientation of the desired axis with respect to the gyroscope sensor unit by normalizing the summed gyroscope readings in the three axes; tracking, by the processor, the orientation of the desired axis of the bone from the gyroscope readings; and displaying, by a display of said system, tracking data from the tracked orientation of the desired axis of the bone.
