Fatigue crack growth in orthopaedic locking compression plates (LCP), under four-point bending, has been simulated by the extended finite element method (xFEM) to assess LCP optimal geometry in respect to remaining life. Loads corresponded to those occurring in human tibia during gait cycle for different body weights (60, 90 and 120 kg). Experimental investigation consisted of tensile testing and fatigue crack growth rate testing of Ti6Al-4 V alloy, as used for LCP, by standard testing using tensile testing machine and Fractomat, respectively. Results showed that the remaining life of LCPs strongly depend on plate geometry and patient body weight (load).
