Assessment of the Bone Mineral Content in the Mandible by Dual-Energy X-Ray Absorptiometry to Evaluate Short-Term Change
With the objective of being able to assess response to disease or clinical treatment, the densitometry community has long sought the ability to assess short-term change in bone density. The mandible, known to have a high bone turnover, an increased vascularity, and a greater susceptibility to osteoclastic and osteoblastic activities, has long been suggested but has fallen short as a site from which to monitor an early change in the response to a treatment or a disease. The current study developed a method to assess bone density in the superimposed left and right mandibles. (Source: Journal of Clinical Densitometry)

Fracture Risk Assessment Tool (FRAX ®) Results Calculated With and Without Bone Mineral Density Values for the Evaluation of Fracture Risk in Postmenopausal Women With Osteopenia
The aim of this study was to evaluate the agreement between fracture risk predictions based on calculations made with and without bone mineral density (BMD) values using the Fracture Risk Assessment Tool (FRAX ®) in Turkish postmenopausal women with osteopenia and to compare the treatment recommendations. This descriptive, cross-sectional study included postmenopausal women aged 50–79 yr with a diagnosis of osteoporosis who were not receiving any treatment. A questionnaire was administered to the par ticipants face-to-face to obtain sociodemographic characteristics, medical history, and fracture history. (Source: Jour...

Height Loss Was Associated With Osteoporosis in Korean Elderly Men, Not in Women: The Korea National Health and Nutrition Examination Survey 2008 –2010
The objective of this study was to examine the relationships between height loss and bone mineral density (BMD) and to assess the prevalence of osteoporosis according to the height loss quartiles. Data from the Korea National Health and Nutrition Examination Survey were analyzed. A total of 2799 participants more than 60 years old were included and subdivided into quartiles according to height loss (Q1 –Q4). (Source: Journal of Clinical Densitometry)

Dual-Energy X-ray Absorptiometry Predictors of Vertebral Deformities in Beta-Thalassemia Major
Vertebral fractures in beta-thalassemia major are increasingly found because of the longer life expectancy of patients, with a major negative impact on their quality of life. We performed a retrospective cross-sectional study to investigate the prevalence of vertebral deformities in thalassemic patients and to identify their best dual-energy X-ray absorptiometry (DXA) predictor among trabecular bone score (TBS), bone mineral density (BMD), and Z-score. Eighty-two outpatients with beta-thalassemia major on regular conventional treatment were studied at a single academic center. (Source: Journal of Clinical Densitometry)

An Investigation Into the Differences in Bone Density and Body Composition Measurements Between 2 GE Lunar Densitometers and Their Comparison to a 4-Component Model
We describe a study to assess the precision of the GE Lunar iDXA and the agreement between the iDXA and GE Lunar Prodigy densitometers for the measurement of regional- and total-body bone and body composition in normal to obese healthy adults. We compare the whole-body fat mass by dual-energy X-ray absorptiometry (DXA) to measurements by a 4-component (4-C) model. Sixty-nine participants, aged 37 ± 12 yr, with a body mass index of 26.2 ± 5.1 kg/cm2, were measured once on the Prodigy and twice on the iDXA. (Source: Journal of Clinical Densitometry)

Tools for Enhancement and Quality Improvement of Peer Assessment and Clinical Care in Endocrinology and Metabolism
Members of the College of Physicians and Surgeons of Ontario Endocrinology and Metabolism Peer Review Network have been involved in a quality improvement project to help standardize the peer assessment of physicians practicing in endocrinology and metabolism. This has included developing state-of-the-art summaries of common endocrine problems by Canadian experts in endocrinology and metabolism. These tools have been developed in response to the educational needs, as identified by peer reviewers, of practicing endocrinologists in Ontario. (Source: Journal of Clinical Densitometry)

Quantitative Ultrasound (QUS) in the Management of Osteoporosis and Assessment of Fracture Risk
The use of quantitative ultrasound (QUS) for a variety of skeletal sites, associated with the absence of technology-specific guidelines, has created uncertainty with respect to the application of QUS results to the management of individual patients in clinical practice. However, when prospectively validated (this is not the case for all QUS devices and skeletal sites), QUS is a proven, low-cost, and readily accessible alternative to dual-energy X-ray absorptiometry (DXA) measurements of bone mineral density (BMD) for the assessment of fracture risk.

Osteoporosis Risk Calculators
Osteoporosis is a silent disease until fractures occur, patient recognition is the greatest clinical challenge. Although more than 20 million women in the US are estimated to have established osteoporosis the majority are not appropriately identified. Bone densitometry is the current gold standard for diagnosis of osteoporosis; but may not be feasible or cost-effective to recommend for all postmenopausal women. Therefore, questionnaires incorporating risk factors have been developed to aid the clinician in identifying women with osteoporosis. (Source: Journal of Clinical Densitometry)

Assessment of Osteoporosis Fracture Risk
Osteoporosis-related fractures (low-trauma, low-impact, fragility) are associated with significant morbidity, mortality, and health-care expenditure worldwide. In the absence of a defining fracture, the diagnosis of osteoporosis is based on the World Health Organization's T-score criteria (less than or equal to −2.5) by central dual-energy X-ray absorptiometry (DXA). Using the World Health Organization's diagnostic criteria, greater than 50% of patients who sustain a low-trauma fracture have a T-score above the diagnostic threshold for osteoporosis.

The Future of Fracture Risk Assessment in the Management of Osteoporosis
There have been many advances in the field of osteoporosis that add to a greater understanding of skeletal integrity and the adverse effects menopause and aging have on bone. The World Health Organization, the International Osteoporosis Foundation, and numerous additional governmental and privately sponsored organizations, societies, and their respective task forces have provided guidance for the use of appropriate fracture assessment methodologies and fracture risk assessment tools, and for the prevention and management of osteoporosis.

Worldwide Fracture Prediction
The substantial increase in the burden of non-communicable diseases in general and osteoporosis in particular, necessitates the establishment of efficient and targeted diagnosis and treatment strategies. This chapter reviews and compares different tools for osteoporosis screening and diagnosis; it also provides an overview of different treatment guidelines adopted by countries worldwide. While access to dual-energy X-ray absorptiometry to measure bone mineral density (BMD) is limited in most areas in the world, the introduction of risk calculators that combine risk factors, with or without BMD, have resulted in a paradigm ...
