Correlations between cancellous bone architecture and its dynamic behaviour
TypeCommunications avec actes
Previous studies showed that in vivo evaluation of the fracture risk of cancellous bone can be assessed by identifying the relationships between its microarchitecture description extracted from clinical imaging and its mechanical properties. The mechanical properties under dynamic loadings (with and without confinement) were obtained and compared to quasi-static ones. The architectural parameters of each specimen were extracted from pQCT images and split into four groups: geometry, topology, connectivity and anisotropy. Results show that architectural parameters are strong determinants of mechanical behaviour for the different applied boundary conditions.

The behavior of cancellous bone from quasi-static to dynamic strain rates with emphasis on the intermediate regime PROT, Marianne; CLOETE, Trevor John; SALETTI, Dominique; LAPORTE, Sébastien (Elsevier, 2016)Previous studies, conducted using quasi-static and dynamic compression tests, have shown that the mechanical strength of cancellous bone is strain rate dependent. However, these studies have not included the intermediate ...
Fracture characterization in cancellous bone specimens via surface difference evaluation of 3D registered pre- and post-compression micro-CT scans PROT, Marianne; DUBOIS, Guillaume; CLOETE, Trevor John; SALETTI, Dominique; LAPORTE, Sébastien (Taylor & Francis, 2015)In recent years, increasingly stringent passenger vehicle safety requirements have led to a renewed interest in the fracture properties of bone. It has been shown that can- cellous bone architecture is strongly linked ...
