HUMAN CORTICAL BONE TOUGHNESS AT TWO STRAIN RATES ON THREE PAIRED ANATOMICAL LOCATIONS
Résumé
Most of the fractures occur at the radius or at the femoral neck after a fall, involving high strain rate (10-1.s-1) [1]. Cortical bone toughness is usually measured under quasi-static loading condition even though it is known to have viscoelastic properties [2]. A recent study on one subject actually showed that the toughness of femoral shaft specimens is lower at a strain rate representative of a fall [3]. We hypothesize this effect could be the same whatever the anatomical location. The aim of this study is thus to quantify human cortical bone toughness using paired radii and femurs (neck and shaft) considering two strain rates (quasi-static and representative of a fall).
