Finite Element Modeling of the Cortical Bone Region Using Clinical CT Images

Journal of Biomechanical Science and Engineering, 2006
Since the cortical bone has higher elastic modulus compared to the cancellous bone, its geometry is very important for stress analysis of bone structure.

Adenine-induced chronic kidney disease induces a similar skeletal phenotype in male and female C57BL/6 mice with more severe deficits in cortical bone properties of male mice.

PLoS ONE, 2021
Chronic kidney disease (CKD) causes bone loss, particularly in cortical bone, through formation of cortical pores which lead to skeletal fragility. Animal models of CKD have shown variability in the skeletal response to CKD between males and females ...

Excessive growth hormone expression in male GH transgenic mice adversely alters bone architecture and mechanical strength [PDF]

, 2015
Patients with acromegaly have a higher prevalence of vertebral fractures despite normal bone mineral density (BMD), suggesting that GH overexpression has adverse effects on skeletal architecture and strength. We used giant bovine GH (bGH) transgenic mice

Influences of organic component on mechanical property of cortical bone with different water content by nanoindentation

AIP Advances, 2018
The phenomenon that water in bone has important influences on mechanical properties of cortical bone has been known. However, the detail of the influence mechanism is not clear, especially in the component hierarchy.

Changes of cortical bone pores structure and their effects on mechanical properties in tail-suspended rats

Medicine in Novel Technology and Devices, 2022
Cortical bone is the main mechanical bearing structure of bone, and the mechanical properties of materials are not only related to bone mineral density, but also largely depend on its pores microstructure which affected by blood vessels.

Higher fracture prevalence and smaller bone size in patients with hEDS/HSD-a prospective cohort study

, 2020
Increased fracture risk in patients with Ehlers-Danlos syndromes has been reported, but the reasons for it are incompletely understood. We aimed to investigate possible determinants of this increased risk and found that hEDS/HSD patients present with a ...

Identification of anisotropic tensile strength of cortical bone using Brazilian test. [PDF]

, 2014
For a proper analysis of cortical bone behaviour, it is essential to take into account both the elastic stiffness and the failure criteria. While ultrasound methods allow complete identification of the elastic orthotropic coefficients, tests used to ...

A CBCT Evaluation of the Proximity of Mandibular Molar Roots and Lingual Cortical Bone in Various Vertical Facial Patterns and Factors Related to Root-Cortical Bone Contact

Applied Sciences, 2023
The objective of this study was to assess the proximity of the mandibular molar roots and the lingual cortical bone in patients with various vertical facial patterns and determine factors related to root-cortical bone contact. A total of 145 patients (84
