Sub-trabecular strain evolution in human trabecular bone [PDF]

Scientific Reports, 2020
AbstractTo comprehend the most detrimental characteristics behind bone fractures, it is key to understand the material and tissue level strain limits and their relation to failure sites. The aim of this study was to investigate the three-dimensional strain distribution and its evolution during loading at the sub-trabecular level in trabecular bone ...

Update on trabecular bone score

Archives of Endocrinology and Metabolism, 2022
Trabecular bone score (TBS) is an indirect and noninvasive measure of bone quality. A low TBS indicates degraded bone microarchitecture, predicts osteoporotic fracture, and is partially independent of clinical risk factors and bone mineral density (BMD).

Cortical unlike trabecular bone loss is not associated with vascular calcification progression in CKD patients

BMC Nephrology, 2020
Background Vascular calcification progression has been associated with the loss of trabecular bone in chronic kidney disease (CKD) patients. There are few data evaluating the relationship between cortical bone loss and vascular calcification in this ...

Different subchondral trabecular bone microstructure and biomechanical properties between developmental dysplasia of the hip and primary osteoarthritis

Journal of Orthopaedic Translation, 2020
Objective: Developmental dysplasia of the hip (DDH) is recognized as a frequent cause of secondary osteoarthritis (OA). The purpose in this study was to compare structural and biomechanical properties of subchondral trabecular bone ​and its relationship ...

Unique suites of trabecular bone features characterize locomotor behavior in human and non-human anthropoid primates. [PDF]

PLoS ONE, 2012
Understanding the mechanically-mediated response of trabecular bone to locomotion-specific loading patterns would be of great benefit to comparative mammalian evolutionary morphology.

Local origins impart conserved bone type-related differences in human osteoblast behaviour [PDF]

, 2015
Osteogenic behaviour of osteoblasts from trabecular, cortical and subchondral bone were examined to determine any bone type-selective differences in samples from both osteoarthritic (OA) and osteoporotic (OP) patients.

Osteoporotic Goat Spine Implantation Study Using a Synthetic, Resorbable Ca/P/S-Based Bone Substitute

Frontiers in Bioengineering and Biotechnology, 2020
One primary purpose of the present study is to clarify whether the highly porous, resorbable Ca/P/S-based bone substitute used in this study would still induce an osteoporotic bone when implanted into the osteoporotic vertebral defects of ovariectomized (

Distributional variations in trabecular architecture of the mandibular bone: an in vivo micro-CT analysis in rats. [PDF]

PLoS ONE, 2015
PURPOSE:To evaluate the effect of trabecular thickness and trabecular separation on modulating the trabecular architecture of the mandibular bone in ovariectomized rats.

Trabecular bone deterioration in a postmenopausal female suffering multiple spontaneous vertebral fractures due to a delayed denosumab injection – A post-treatment re-initiation bone biopsy-based case study

Bone Reports, 2023
Background: Denosumab, is a potent anti-resorptive that, increases bone mineral density, and reduces fracture risk in osteoporotic patients. However, several case studies have reported multiple vertebral fractures in patients discontinuing denosumab ...

Effect of trabecular bone loss on cortical strain rate during impact in an in vitro model of avian femur

BioMedical Engineering OnLine, 2006
Background Osteoporotic hip fractures occur due to loss of cortical and trabecular bone mass and consequent degradation in whole bone strength. The direct cause of most fractures is a fall, and hence, characterizing the mechanical behavior of a whole ...
