Simulation for preoperative planning and intraoperative application of titanium implants

Towards semi-automated transfer of preoperatively planned bone repositionings in the operation theatre, this paper presents a solution by performing preoperative bending of common titanium plate implants. The approach is based on our simulation system KasOp which defines preoperatively bone cut trajectories and bone repositionings. According to physiological matters the segments are repositioned and the computer models of the implants are bended in respect to physical constraints following the physiological shape of a bone of same age and sex. We are in process of developing a bending device which can bend standard titanium implants corresponding to the simulation. Therefore, precast implants can be used during surgery speeding up the fixation procedure of the cut bone segments.
