Simulation-based design of patient-specific femoral locking plate using topology optimization

Abstract

Femoral locking plates are orthopedic implants used in closed reduction of the fractured femur. These orthopedic implants designed using conventional methods apply finite element analysis to evaluate their performance. These traditional approaches result in failure of implants and need for revision surgery. Designing a patient-specific or a customised implant can make a substantial difference to the expected performance response and reduce the failure or breakage of implant. Therefore, a simulation-based design approach is employed which encompasses medical imaging segmentation, finite element analysis, Taguchi design methodology and topology optimization. The intent is to provide a methodology that will help surgeons to make informed decisions backed by engineering analysis.
