Abstract

The patent discloses a system and method for correcting changes in the shape of joint bones in a bone joint, including: providing a three-dimensional imaging data set of a bone joint; identifying the joint bones in the data set based on the shapes of the joint bones; inscribing a portion of a joint bone to be reconstructed with a base shape; determining contour deviations of the inscribed joint bone from the base shape by ascertaining contour distances between the base shape and the shape of the inscribed joint bone in different incision planes; determining a three-dimensional deviating volume using the contour deviations; and using the deviating volume for correction planning.
