Part comparison analysis for the example of radius in case 5 (distances in mm). a Preoperative versus planned part: only 41% of surface points are situated in the range of − 3 mm to + 3 mm. The red colour of the preoperative part indicates a deviation of > 3 mm from the planned part. b Postoperative versus planned part. 99% of surface points are situated in the range of − 3 mm to + 3 mm. Green colour of the postoperative part shows the same position as the two parts. The analysis statistics and histogram show the minimum and maximum deviations of the two parts, the mean value of the point deviations, and the statistical dispersion of the same
