Compliance with prescribed drugs is poor in most chronic conditions and osteoporosis is no exception. Compliance integrates the concepts adherence (how much drug is taken) and persistence (for how long) and also if the patient follow the instructions for a correct use of the medication. Between 50 and 75% of patients initiating antiosteoporosis drugs are not taken the treatment 1 year later. Obviously, this problem significantly decreases the effect of drugs. A smaller increas...

Incidence of vertebral fractures in the EU has been estimated in 520 000 for the year 2010. Clinical vertebral fractures cause most of the impact in terms of morbidity, quality of life and economic burden. However, even the sub-clinical ones are not neutral in these aspects. Unlike hip fractures, their incidence is less dissimilar across Europe. Mortality in the first year after a vertebral fracture is higher than for hip fracture, especially in the younger age groups. Vertebr...

No treatment for osteoporosis abolishes the risk of fracture. Even under the ‘ideal’ conditions of adherence and monitoring, in the controlled pivotal trials, a significant proportion of individuals receiving the active drug still suffer new fractures. In everyday practice the situation is even more challenging. Adherence to medication is poor, patients are often older than in trials, or suffer from a number of comorbidities that could have excluded them from the ori...

Anabolic drug (AD) options are currently limited to PTH analogs. With potent bone-forming effects, AD offer marked increases in BMD. However, the demonstration of their efficacy on fracture risk reduction was possibly limited by the early discontinuation of the pivotal trial for safety concerns. Therefore, their use must rely both in the available evidence as well as in the clinical judgment for the individual patient. Indeed, potential contraindications are the first step in ...

A micro-indentation technology potentially allows in vivo investigation of intrinsic bone tissue quality, a determinant of bone fragility. Thus the signification of the parameters investigated is still unclear.Since protein malnutrition affects bone material level properties – geometry and strength – rats were fed a normal or an isocaloric low-protein diet. Both femurs were collected and measurements of geometry using micro CT, materia...

Impaired bone material properties have been invoked as being responsible for the development of atypical femoral fractures (AFF) after long term bisphosphonate use. We therefore analyzed bone material properties in a bone biopsy obtained at the fracture site from an 88-year-old female with AFF, who had been treated with alendronate for 8 years. We used conventional histology, quantitative backscattered electron imaging (qBEI), and Raman spectroscopy (RS).<p class="abstext"...

Hip+ fracture rate in Norway is the highest registered in World, and more than double that of Spanish women. Previous studies were unable to demonstrate significant differences between the two populations with respect to bone mass or calcium metabolism. In order to test, whether the difference in fracture propensity between both populations could be explained by differences in bone material quality we assessed bone material strength using microindentation in 41 Norwegian and 4...

Purpose: To determine the association between socio-economic status (SES) and risk of hip fracture.Methods: Retrospective cohort study. We used a population database which contains primary care and hospital inpatient records of over >5 million people. Anyone registered in this database in 2009–2012 and resident in an urban area was eligible. Main measures: a validated SES composite index (accounting for proportion of unemployed, insufficiently e...
