Summary
The results of the surgical correction of scoliosis through posterior approach have significantly improved by the introduction of new implants during the past decades. Even with these improvements the available implants only allow limited correction especially regarding axial rotation, and also their application is rather complicated. We developed a new implant which simultaneously grasps and exerts forces on both transverse processes of the vertebrae, to achieve a more efficient and safer correction with a simple surgical technique. In our paper we report on the concept of the new implant, its most important features, its mechanical tests, cadaver experimentations, and biomechanical assessments.
