Abstract

A method and system of computer assistance to the preparation of the reduction of a fracture such that a patient's bony fragments are separated into first and second bone segments, with in bone segments being symmetrical to a third bone element. The method includes the steps of determining a first representation or bone model of the surface of the first bone segment, a second representation, at an initial position, of the second segment, and a third representation of the third bone element; determining by symmetry a fourth representation of the first and second bone segments of the fractured bone in the absence of a fracture, the fourth representation being matched with the first representation; matching the second representation with the fourth representation at a final position; and providing, by an interface element, information representative of the difference between the initial position and the final position.
