We evaluated the prevalence and geographic variation of short-interval (repeated in under 2 years) dual-energy X-ray absorptiometry tests (DXAs) among Medicare beneficiaries. Short-interval DXA use varied across regions (coefficient of variation = 0.64), and unlike other DXAs, rates decreased with payment cuts. ⋯ One out of ten DXAs was administered in a time frame shorter than recommended and at a substantial cost to Medicare. DXA use varied across regions. Short-interval DXA use was responsive to reimbursement changes, suggesting carefully designed policy and payment reform may reduce this care identified by rheumatologists as low value.

Only few studies have been published hitherto on country-specific incidence of distal forearm fracture. In the prevailing study, incidences were estimated, and trend analyses were performed for the entire Austrian population aged ≥50á. Incidence decreased significantly in women, but not in men, over the past 12 years of observation. ⋯ Incidence of distal forearm fracture in the entire Austrian population is comparable to hip fracture incidence which is known to be among the highest worldwide. However, trend analyses reveal a significant decrease for all distal forearm fractures in women, but not in men, over the last 12 years.

Spinal cord injury (SCI) causes rapid and marked bone loss. The present study demonstrates that low-intensity vibration (LIV) improves selected biomarkers of bone turnover and gene expression and reduces osteoclastogenesis, suggesting that LIV may be expected to benefit to bone mass, resorption, and formation after SCI. ⋯ The findings demonstrate an ability of LIV to improve selected biomarkers of bone turnover and gene expression and to reduce osteoclastogenesis. The study indicates a possibility that LIV initiated earlier after SCI and/or continued for a longer duration would increase bone mass.
