The logic can determine how to restore the bone segments. The logic can transmit one or more images for display with the at least two bone segments. The logic can identify a first restoration point and a third point on a first bone segment and a second restoration point and a fourth point on a second bone segment. The logic can identify a fifth point on the first bone segment and a sixth point on the second bone segment. The logic can also divide one or more images along a line or plane between the bone segments, bring the second restoration point and associated image segment to the first restoration point, align the line or plane of the second bone segment with the line or plane of the first bone segment. Further, the logic can adjust for the alignment and record the movement of the image segment or compare the original position and the final position to determine deformation parameters.
