A method for pre-operative planning a surgical intervention, and computing system

摘要

The present invention relates to a method and an arithmetic unit (10) having a program code for pre-operative planning of a surgical intervention, to be carried out after a longer fragment fracture of a bone (k) with:– Transfer of a 3d - representation of the, in bone fragments (f1– F5) fractured bone (k),– Segmentation of the individual bone fragments (f1, f5),– Generation of a physical simulation (f1 ’ – f5 ’) of the segmented bone fragments (f1, f5),– repositioning the simulated bone fragments (f1 ’ – f5 ’) to an anatomically correct bone model (km),– Determination of the relative position of the repositioned position and position of the simulated bone fragments (f1 ’ – f5 ’) in the repositioned state,– Determination of the relative linear displacement (t2, t4) and the relative rotation (r2, r4) between the simulated bone fragments (f1 ’ – f5 ’) in the bone model (km) and the corresponding bone fragments (f1, f5) in the 3d - representation,– Creating and output or storage of an operation plan, in which the relative displacement (t2, t4) and the relative rotation (r2, r4) for repositioning for each of the bone fragments (f2 are predetermined – f4).
