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.

Effect of micro-computed tomography voxel size and segmentation method on trabecular bone microstructure measures in mice

Bone Reports, 2016
Micro-computed tomography (μCT) is currently the gold standard for determining trabecular bone microstructure in small animal models. Numerous parameters associated with scanning and evaluation of μCT scans can strongly affect morphologic results ...

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 ...

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

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 (

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 ...

Cortical and trabecular bone microarchitecture as an independent predictor of incident fracture risk in older women and men in the Bone Microarchitecture International Consortium (BoMIC): a prospective study.

The Lancet Diabetes and Endocrinology, 2019
BACKGROUND Although areal bone mineral density (aBMD) assessed by dual-energy x-ray absorptiometry (DXA) is the clinical standard for determining fracture risk, most older adults who sustain a fracture have T scores greater than -2·5 and thus do not meet

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 ...

The role of bone marrow on the mechanical properties of trabecular bone: a systematic review

BioMedical Engineering OnLine, 2022
Background Accurate evaluation of the mechanical properties of trabecular bone is important, in which the internal bone marrow plays an important role.
