The main purpose of this paper is to develop a new adapted osteosynthesis implant, used for transsindesmotic fibula’s fracture. We have chosen to design this medical implant, because the lateral malleolar fracture represents from 40% to 45% of skeletal fractures. At the present moment, orthopaedic screws and metallic plates do the osteosynthesis of this region, but the results are not satisfactory. In order to reduce the healing time of the fractured bone, we have considered optimiz­ing the geometrical shape of the existing osteosynthesis metallic plate, thus to fulfil two major functionalities such as implant’s capacity to adapt to the bone surface and keeping the periosteum vascular circulation in the contact region. The proposed solution is based on a method, which combines the medical image processing techniques and CAD modelling.
