Highlights

Distal radius fractures are the most common upper extremity fractures in adults (65 years and older) occurring after a fall from standing height or lower (Vogt et al 2002). These fractures are associated with age related decline in bone quality and because they occur earlier in life than other osteoporotic fractures, they can be interpreted as a warning signal for later and more deleterious fractures (Melton et al 2010)
Radius bone strain can be predicted by finite element analysis in forward fall configuration
ResultsResults and discussionDue to experimental issues, only 27 bones were tested successfully

Summary

Introduction

Distal radius fractures are the most common upper extremity fractures in adults (65 years and older) occurring after a fall from standing height or lower (Vogt et al 2002). These fractures are associated with age related decline in bone quality and because they occur earlier in life than other osteoporotic fractures, they can be interpreted as a warning signal for later and more deleterious fractures (Melton et al 2010). Subject-specific finite elements models have been proposed to evaluate both bone strain and fracture risk. The main aim of the current study was to assess the surface strains prediction of radius specimen-specific finite element models
