Finite Element Analysis of Existing and Modified Intramedullary Rod for Orthopedic Applications

Abstract

Finite Element Analysis (FEA) has been used in the field of biomedical engineering and especially in biomechanics, which helps to predict and validate feasible designs for complex cases. The role of biomechanics has grown steadily in the field of orthopedic surgery. For example, fixation was performed to stabilize a large femoral bone fragment. Femoral injury is analyzed in real time, and the experiment provides a three-dimensional visualization of finite elements designed to explain the mechanical properties of the femur. Modified trapezoidal nail shape is used in the modified intramedullary rod setup in order to obtain additional strength and stability. It also provides resistance to femoral head rotation. Potentially it improves patient mobility and recovery since the modified design is in par with the anatomy of the human femur bone.
