O3117 NEW BIOLOGICAL METHOD OF INTERNAL FIXATION OF THE FEMUR

Abstract

Aims: The purpose of this abstract is to present one new minimally invasive method and one 3D device for internal þxation. Methods: The device is constructed to be self-dynamisable. It has been investigated biomechanicaly. In clinical use it has been applied to 34 patient. Twenty-nine applications have been performed to the femoral comminuted fractures, four in established femoral non-union and one in pathological metastatic fracture. The age of patients was from 17 to 73 years. Twenty-three were mail and eleven females. This internal þxator is applied by small incisions using indirect or direct fracture reduction. Results: Received clinical results are promising, as it has been shown early callus formation and radiological union within the 3–4 months. It has been allowed to patients early full weight bearing. During the treatment it has been conþrmed working of self-dynamisation concept, which probably all together with 3D conþguration resulted in unexpectedly quick fracture healing. Follow up was 11 months (3–27). This concept is compatible with reduction device developed by the author and mechanical monitoring device recently developed by the author and Professor Perren in Davos. Conclusions: According to the þrst 34 patients, it can bee concluded that new internal þxator can be successfully used routinely in every day practice.
