Abstracts
Patient-specific orthopaedic implant application improves the recovery of the fractured bone in comparison to the conventional implant of standardized shape and size. The main challenge regarding creation of this kind of implant is its design process because the conventional modelling techniques based on using NURBS for shaping the unique bio-forms take a lot of time and effort. The research found out that the application of combination of two design techniques may accelerate the whole design process for more than 60% comparing to the conventional approach while improving the geometric congruency of the implant and the bone. The first is about digital reconstruction of the bone geometry by the polygonization of the synthetic cloud of points built on radiographic images of the injured bone. The second is applying semi-automated surface subdivision modelling technique for shaping the implant. The research was done for the case of designing the internal fixator of Mitkovic type aimed for lateral tibial plateau fracture.
