Multicenter Study
Generation and validation of a normative, age-specific reference curve for lumbar spine trabecular bone score (TBS) in French women.
Age-related changes in lumbar vertebral microarchitecture are evaluated, as assessed by trabecular bone score (TBS), in a cohort of 5,942 French women. The magnitude of TBS decline between 45 and 85 years of age is piecewise linear in the spine and averaged 14.5%. TBS decline rate increases after 65 years by 50%. ⋯ The age-specific reference curve for TBS generated here could therefore be used to help clinicians to improve osteoporosis patient management and to monitor microarchitectural changes related to treatment or other diseases in routine clinical practice.

We report the bone attenuation of ankle joint measured on computed tomography (CT) and the cause of injury in patients with ankle fractures. The results showed age- and gender-dependent low bone attenuation and low-energy trauma in elderly females, which suggest the osteoporotic features of ankle fractures. ⋯ Ankle fracture had features of osteoporotic fracture that is characterized by age- and gender-dependent low bone attenuation. Ankle fracture should not be excluded from the clinical and research interest as well as from the benefit of osteoporosis management.

Our fracture liaison service identifies patients with low trauma fractures, determines the need for osteoporosis therapy and instigates therapy if necessary. We describe the tracking and outcome of 768 patients attending our emergency department over 1 year and discuss the problems we encountered and potential solutions. ⋯ Our fracture liaison service was effective at identifying most low trauma fracture patients at risk of further fracture and providing access to osteoporosis assessment. There were many difficulties: we outline logistic and practical issues in delivering our service and suggest potential improvements.

Changes in frailty-related characteristics of the hip fracture population and their implications for healthcare services: evidence from Quebec, Canada.
This study provides evidence that a number of frailty-related characteristics (older age, de novo admission to long-term care (LTC), comorbidities [Charlson Index, osteoporosis, osteoporosis risk factors, sarcopenia risk factors, and dementia]) have increased in the hip fracture population from 2001-2008. This will have significant impact on community resources, as the number of people discharged to the community is also increasing. ⋯ Although hip fracture rates decreased for older hip fracture patients, the absolute number and prevalence of specific frailty-related characteristics increased. Policy makers should review care models to ensure that adequate resources are provided to the community to offset the expected increase in demand arising from ongoing changes in patients' characteristics.

The aim of this study is to identify osteoporosis values, beyond which there is a high risk of osteosynthesis failure. Bone mineral density (BMD) of 30 cadaveric femora with a pertrochanteric fracture osteotomy was correlated to the risk of cut out after osteosynthesis on a biomechanical testing approach. For a BMD less than 250 mg/cm(3), there is a high risk of fixation failure after surgical treatment of pertrochanteric fractures. This value can be regarded as a reference value for future experimental and clinical studies. ⋯ For a BMD less than 250 mg/cm(3), there is a high risk of fixation failure after surgical treatment of pertrochanteric fractures. Although this value is based on an experimental in vitro study design with all its associated limitations, it can be regarded as a reference value for future experimental and clinical studies.
