Abstract

Fractures of the forearm are among the most common orthopedic injuries. Marginally displaced fractures are usually treated by closed reduction or immobilization. However, depending on the degree of displacement, bone healing in non-anatomic position (malunion) may result, leading to pain, functional impairment, and aesthetic problems. Particularly, deformities of the forearm bones can cause impingements and increased tension in ligaments, resulting in a limitation of the range of motion. A corrective osteotomy has become the standard treatment for malunited forearm bones to reconstruct normal anatomy. We present a comprehensive computer-aided planning system for corrective osteotomies. The key concept of our approach is to directly use the 3-d information of a patient's bone morphology, available from the CT data, in the comparison to the contralateral bone. The proposed semi-automatic 3-d approach improves the accuracy of the planning compared to conventional 2-d methods that rely on manual measurements.
