Abstract EN
The elderly are more likely to suffer from fracture because of age-related trabecular bone loss.
Different bone loss locations and patterns have different effects on bone mechanical properties.
Extended finite element method (XFEM) can simulate fracture process and was suited to investigate the effects of bone loss on trabecular bone.
Age-related bone loss is indicated by trabecular thinning and loss and may occur at low-strain locations or other random sites.
Accordingly, several ideal normal and aged trabecular bone models were created based on different bone loss locations and patterns; then, fracture processes from crack initiation to complete failure of these models were observed by XFEM; finally, the effects of different locations and patterns on trabecular bone were compared.
Results indicated that bone loss occurring at low-strain locations was more detrimental to trabecular bone than that occurring at other random sites; meanwhile, the decrease in bone strength caused by trabecular loss was higher than that caused by trabecular thinning, and the effects of vertical trabecular loss on mechanical properties were more severe than horizontal trabecular loss.
This study provided a numerical method to simulate trabecular bone fracture and distinguished different effects of the possible occurrence of bone loss locations and patterns on trabecular bone.
