Design of Osteoflxation Devices - Personalised Approach

摘要

Treatment of patients after major bone trauma, regardless of whether they are caused by fractures, osteoporosis, cancer or infections, require application of implants, fixators, scaffolds or other osteoflxation devices. The speed and quality of bone regeneration depends to a large extent on degree of adaptability of implants or fixators to a specific patient and a specific trauma. The personalized approach to design makes it possible to create the devices most suited to the patient. For the design of personalized osteoflxation devices, a 3D geometric model of bone before trauma is needed. However, in case of major trauma, there is usually no longer a part of the bone, so it is not possible to create a 3D model of the entire bone. The paper presents original methods for reverse engineering of human bones even in cases where there is no medical picture of the complete bone. Also, it is shown how such a model is applied for the design of personalized osteoflxation devices.
