Reliability Based Design of Femoral Locking Plate Systems

Reliability based design and optimization approach is developed for femoral locking plate systems. The new approach encompasses finite element analysis, advanced probabilistic analysis, and robust design methodology. A three dimensional finite element model of a locking plate system with a supracondylar femoral fracture will be generated to investigate the device performance. The model will include all physiological loading conditions-hip contact, knee contact, and muscle forces-associated with a normal walking gait cycle. In conjunction with probabilistic methods, Taguchi design optimization will be used to optimize implant design to minimize the probability of failure.Copyright © 2016 by ASME
