Cortical Bone Microarchitecture in Dialysis Patients

American Journal of Nephrology, 2020
<b><i>Background:</i></b> The incidence of skeletal fractures is high in dialysis patients. Current available tools are insufficient to predict bone fragility. We analyzed the microarchitecture in patients on dialysis therapy using bone biopsies and peripheral microcomputed tomography.

Bone vascularization: a way to study bone microarchitecture?

SPIE Proceedings, 2014
Trabecular bone and its microarchitecture are of prime importance for health. Studying vascularization helps to better know the relationship between bone and vascular microarchitecture. This research is an animal study (nine Lewis rats), based on the perfusion of vascularization by a contrast agent (a mixture of 50% barium sulfate with 1.5% of gelatin)

Relationship Between Sex Steroids and Deterioration of Bone Microarchitecture in Older Men: The Prospective STRAMBO Study

Journal of Bone and Mineral Research, 2019
International audienceIn older men, low estrogen levels are associated with poor bone microarchitecture. Data on androgens are discordant. We studied the link between baseline sex steroid levels (total 17β -estradiol [17βE2], total testosterone [tT ...

Bone density and microarchitecture in endogenous hypercortisolism

Clinical Endocrinology, 2015
SummaryObjectiveOsteoporosis is a serious and underestimated complication of endogenous hypercortisolism that results in an increased risk of fractures, even in patients with normal or slightly decreased bone mineral density (BMD). Alterations in bone microarchitecture, a very important component of bone quality, may explain bone fragility.

Imaging techniques for evaluating bone microarchitecture

Joint Bone Spine, 2006
At present, fracture risk prediction in the individual patient relies chiefly on bone mineral density (BMD) measurements. However, many lines of evidence indicate that the decreased bone strength characteristic of osteoporosis is dependent not only on BMD, but also on other factors, most notably bone microarchitecture.

Noninvasive assessment of bone microarchitecture by MRI

Current Osteoporosis Reports, 2006
In determining fracture risk, it has become apparent that bone mineral density accounts for only a portion of bone strength, with the remainder being determined by the material and structural properties of the bone tissue. Over the past 15 years, high-resolution MRI has provided a window into the structural nature of bone disease.

Surface curvatures of trabecular bone microarchitecture

Bone, 2002
Microstructure of trabecular bone has been examined with a particular emphasis on surface curvatures in two-phase (trabecular and intertrabecular space- i.e., marrow space) structures. Three trabecular bone samples, quantified as "plate-like," "rod-like," and a mixture of these two structural elements according to the structure model index (SMI), were ...

Composition and microarchitecture of human trabecular bone change with age and differ between anatomical locations

Bone, 2013
The microarchitecture of trabecular bone adapts to its mechanical loading environment according to Wolff's law and alters with age. Trabecular bone is a metabolically active tissue, thus, its molecular composition and microarchitecture may vary between ...

Microarchitectural Pattern of Pristine Maxillary Bone

The International Journal of Oral & Maxillofacial Implants, 2015
There is limited evidence available on the influence of location on bone density in the maxilla. Therefore, this study was aimed at comparing the microarchitecture of bone harvested from different nonatrophic maxillary locations.A total of 37 partially edentulous subjects (aged 48.15 ± 15.85 years) were included in the study.

Bone turnover correlates with bone quantity but not bone microarchitecture in chronic hemodialysis

Journal of Bone and Mineral Metabolism, 2020
In chronic hemodialysis, high-turnover bone disease was associated with decreased bone mineral density (BMD), poor bone quality (chemical and structural), and increased fracture risk. Our aim was to correlate bone turnover markers (BTMs) with bone microarchitecture measured by trabecular bone score (TBS) before and after correction for BMD.We measured ...
