Trabecular micro-architecture of the proximal femur during post-natal growth

In sharp contrast to the great interest in morphology of the proximal femur in aged individuals, there is a paucity of studies in children. To date, a comprehensive quantitative analysis of trabecular micro-architecture in various biomechanically relevant subregions of the immature proximal femur has been lacking. The aim of this study was to characterize postnatal development of trabecular bone in various regions of the human proximal femur. The study sample was comprised of ...

Morphology of muscle attachment sites and microarhitecture of underlying bone as the markers of physical activities of past populations

Habitual physical activities of past populations are frequently reconstructed based on musculoskeletal markers (MSM) in human skeletal remains, i.e. particular morphological features of muscles attachment sites. However, the relationship between muscular activity and bone microstructure at the site of muscle attachments is unexplored. Therefore, this study aimed at analyzing bone microstructural characteristics of the muscles attachments sites and correlating these features wi...

Despite widely accepted classical mechanical theory of buttresses as a load bearing areas in the midfacial skeleton, the data related to its microstructural adaptation on functional demands are scarce. In this study we investigated microstructural features of the different regions in the facial bones in relation to the occlusal load dissipation using a combination of finite element analysis (FEA) and micro-CT analysis (╬╝CT). The FEA was performed on the model of the dry h...

Micro-morphological properties of osteons reveal changes in cortical bone stability during aging, osteoporosis and bisphosphonate treatment in women

Bone remodeling is the key process in bone structural reorganization, and its alterations lead to changes in bone mechanical strength. Since osteons reflect different bone remodeling patterns, we hypothesize that the femoral cortex of females with miscellaneous age, disease, and treatment conditions will display distinct osteonal morphology and osteocyte lacunar numbers along with different mechanical properties.The specimens used in this study were coll...
