“…Numerical analysis was typically performed using the finite element method (FEM). Edwards et al [ 21 ], Matsuura et al [ 22 ], Mancuso et al [ 23 ], and Revel et al [ 24 ] conducted finite element analysis (FEA) using finite element models of the radius or wrist bones. The simulation quantitatively evaluated the stress and strain at the distal radius, and the results were considered reasonable when compared to the results obtained from the experimental study.…”

Distal radial fractures exhibit various fracture patterns. By assuming that the strain distribution at the distal radius affects the diversification of the fracture pattern, a parameter study using the finite element model of a wrist developed from computed tomography (CT) images was performed under different loading conditions. The finite element model of the wrist consisted of the radius, ulna, scaphoid, lunate, triquetrum, and major carpal ligaments. The material properties of the bone models were assigned on the basis of the Hounsfield Unit (HU) values of the CT images. An impact load was applied to the scaphoid, lunate, and triquetrum to simulate boundary conditions during fall accidents. This study considered nine different loading conditions that combine three different loading directions and three different load distribution ratios. According to the analysis results, the strain distribution at the distal radius changed with respect to the change in the loading condition. High strain concentration occurred in regions where distal radius fractures are commonly developed. The direction and distribution of the load acting on the radius were considered to be factors that may cause variations in the fracture pattern of distal radius fractures.
