Research progress on application of finite element analysis in internal fixation of distal femoral fractures

Most distal femoral fractures are comminuted and unstable, often involving the articular surface, and internal fixation is the preferred treatment for distal femoral fractures. Finite element analysis method can be used to study the reconstruction and simulation of the distal femur, explore the injury mechanism of fracture, analyze the biomechanical characteristics of different internal fixations, and guide the improvement of internal fixation methods and materials. This study reviewed the finite element modeling of distal femur and clinical application value from the perspective of finite element analysis.
