Osteoporosis is a significant health problem in the older population affecting at least 40% of women and 15 % of men over the age of 50 years. Fracture leads to increased morbidity and mortality and healthcare costs as well as predisposing to future fractures. Patients with a history of low-energy fracture are at significantly increased risk for further fractures in the short-term. There is a universal consensus supported by high-quality randomized trial evidence for secondary prevention: patients with low-trauma fragility fractures should have BMD testing and most of them would benefit from anti-osteoporotic treatment There is, unfortunately, also a well-documented and near-universal gap between evidence-based best practice and usual care for patients with fragility fractures. Although osteoporotic fracture indicates a two- to threefold increased risk of future fracture, only one in five patients receive medical intervention after sustaining an osteoporotic fracture. Diverse post fracture interventions have been developed for improving osteoporosis diagnosis and treatment: provided educational materials to patients and/or primary physician, use of medical reminders, more intensive interventions using osteoporosis case manager (nurse, doctor) and fracture liaison service. the most effective post fracture interventions are those which are more proactive, complex, time consuming, coordinator manager dependant, and costly. Taking account the costs and the humans resources needing, we propose to improve post fracture patient management using mobile telecommunication already used for other chronic diseases management. There is no study about the use of phone short message service (SMS) support in the field of osteoporosis, especially in the post-fracture management: bone mineral density (BMD) screening, anti-osteoporotic treatment initiation and monitoring and improvement of adherence. One of the limitations could be the use of phone mobile in these older patients. We assessed the number of mobile phone users among 100 consecutive subjects who were hospitalized for non vertebral fracture (mean age 69.5 years (50-98); 58 women and 42 men) in the Emergency department of Cochin hospital: 61 % had a mobile phone and used SMS; 61% have a mobile phone.
