Abstract

A bone fracture is treated by employing a database with comparison data records. The records each include at least one 3D image data record of at least one bone. Each comparison data record is assigned to an examination object, into which a comparison implant was implanted prior to recording the 3D image data record. A two-dimensional x-ray image of a target bone is generated. A 2D/3D registration of the x-ray image with 3D image data records is effected and a deviation value is calculated for each comparison data record. A reference data record is determined by selecting the comparison data record that includes the 3D image data record with the lowest deviation value. An implantation parameter is determined which describes a parameter of the implant and/or of a fastening element for fastening the implant, using the reference data record and/or displaying data of the reference data record on a display.
