A vertebral spreading instrument for moving apart two vertebrae of a spine includes a plurality of spreading fingers and a spreading mechanism for adjusting a distance between the spreading fingers. The spreading mechanism includes a first and a second part, the first and second parts each including a respective marker trackable by a navigation system. Relative positions of the first and second parts change when the distance between the spreading fingers is adjusted, and different relative positions are unequivocally assigned to different distances of the spreading fingers.
