Our aim was to determine the prevalence of radiographically defined vertebral deformity, as a marker of vertebral osteoporosis, in different regions and populations within Europe. We used a cross-sectional population-based survey. Population-based sampling frames were obtained from 36 centers in 19 European countries. Stratified random sampling was used to(More)
UNLABELLED ONJ has been increasingly suspected to be a potential complication of bisphosphonate therapy in recent years. Thus, the ASBMR leadership appointed a multidisciplinary task force to address key questions related to case definition, epidemiology, risk factors, diagnostic imaging, clinical management, and future areas for research related to the(More)
BACKGROUND Strontium ranelate, a new oral drug shown to reduce vertebral fracture risk in postmenopausal women with osteoporosis, was studied in the Treatment of Peripheral Osteoporosis (TROPOS) study to assess its efficacy and safety in preventing nonvertebral fractures also. METHODS Strontium ranelate (2 g/d) or placebo were randomly allocated to 5091(More)
UNLABELLED Oral daily (2.5 mg) and intermittent ibandronate (between-dose interval of >2 months), delivering a similar cumulative exposure, were evaluated in 2946 osteoporotic women with prevalent vertebral fracture. Significant reduction in incident vertebral fracture risk by 62% and 50%, respectively, was shown after 3 years. This is the first study to(More)
The lack of standardization in bone mineral measurements of the lumbar spine and other skeletal sites is generally recognized as an important and unresolved issue. We report and discuss efforts at standardization and cross-calibration of DXA and QCT equipment. We have designed and tested a geometrically defined, semi-anthropomorphic phantom, the European(More)
In this study we investigated metabolic power during whole-body vibration exercise (VbX) compared to mild resistance exercise.

In Germany, accurate data on the prevalence and treatment of osteoporosis, as well as the cost of this illness, are not available. The aim of this study is to give a valid estimation of these items for the year 2003. Routine data from a German sickness fund covering 1.5 million beneficiaries and billing data for outpatient visits were used to obtain(More)
Vibration exercise (VE) is a new neuromuscular training method which is applied in athletes as well as in prevention and therapy of osteoporosis. The present study explored the physiological mechanisms of fatigue by VE in 37 young healthy subjects. Exercise and cardiovascular data were compared to progressive bicycle ergometry until exhaustion. VE was(More)
This randomized, double-masked, placebo-controlled trial evaluated the safety, tolerability and effects on bone mineral density (BMD) of alendronate in a large, multinational population of postmenopausal women with low bone mass. At 153 centers in 34 countries, 1908 otherwise healthy, postmenopausal women with lumbar spine BMD 2 standard deviations or more(More)
Whole-body vibration (WBV) is receiving increasing interest as a therapeutic modality to improve neuromuscular performance or to increase bone mass or density. In order to help improve the quality of reports about WBV treatment studies, the International Society of Musculoskeletal and Neuronal Interactions (ISMNI) invited experts in the field to provide(More)
