An automated image processing method is presented for simulating areal bone mineral density measures using high-resolution peripheral quantitative computed tomography (HR-pQCT) in the ultra-distal radius. The accuracy of the method is validated against clinical dual X-ray absorptiometry (DXA). This technique represents a useful reference to gauge the utility of novel 3D quantification methods applied to HR-pQCT in multi-center clinical studies and potentially negates the need for separate forearm DXA measurements. ⋯ The results demonstrate that aBMD can be simulated from HR-pQCT images of the distal radius. This approach has the potential to serve as a surrogate forearm aBMD measure for clinical HR-pQCT studies when axial bone mineral density values are not required.

Multicenter Study
Incidence of hip fracture in the Republic of Ireland and future projections: a population-based study.
There are no previously published data for hip fracture incidence rates in the Republic of Ireland. The rates of fracture for the total population aged 50 years and over were 407 and 140 per 100,000 for females and males, respectively. Assuming a stable incidence rate, the absolute number of hip fractures occurring on an annual basis is expected to increase by 100% by the year 2026. Health care providers should accommodate these increases into future strategies. ⋯ Health service providers should take into account the expected increase in hip fracture numbers when allocating resources for the care of these patients in the mid-term future.

This study was undertaken to investigate the radiologic and clinical outcomes of vertebroplasty with calcium phosphate (CaP) cement in patients with osteoporotic vertebral compression fractures. The morphological changes of injected CaP cement in osteoporotic compressed vertebral bodies were variable and unpredictable. We suggest that the practice of vertebroplasty using CaP should be reconsidered. ⋯ The morphological changes of the injected CaP cement in the vertebral bodies were variable and unpredictable. The compression of the CaP-augmented vertebrae progressed continuously for 2 years or more. The findings of this study suggest that vertebroplasty using CaP cement should be reconsidered.
