[Osteoporosis in the elderly].

Osteoporosis is a frequent disease among the elderly and has major consequences in terms of mortality, morbidity and cost. Guidelines for diagnostic procedures are often difficult to apply in frail, elderly patients with multiple comorbidities. Bisphosphonates are the reference treatment for the elderly, combined with vitamin D and calcium supplementation. Vitamin D deficiency must also be treated to prevent falls and fractures. Strontium ranelate is a promising treatment in this population. Fall prevention is a major part of osteoporosis management. The potential benefit of hip protectors is questionable, even in institutionalized patients.
