| 摘要 |
The present invention is comprised of a method for determining, in three dimensions, where to position fixating means (32) in bone structure fracture s (30) by pre-surgery analysis of at least one anteroposterior and one lateral digitized radiograph of a fracture. The method is applied to control arrangements (100, 140, 150, 200) with a tool for perforating bones in the correct direction in order to accomplish a best possible healing of a fractured bone structure (30), thereby determining positions, distances, X-r ay distorsion etc. |
