Abstract

Fragility fractures are usually related to other successive osteoporotic fractures [1-3]. Patients presenting a hip fracture, may suffer another sudden fall with the result of a contralateral hip fracture, a distal radius fracture, a proximal humeral fracture, a vertebral fracture or a periprosthetic fracture. Despite all the efforts for increasing bone mineral density (medical treatment, nutritional advice and moderate exercise), elderly patients keep falling down and presenting bone fractures. On the other side, aging has a direct impact on the skeletal muscle system: it is not only skeletal muscle mass loss, but also loss of muscle power and reaction speed; the so call sarcopenia. Little interest has been taken on this loss of muscle function, which might be related to the increase in the number of falls. And falls are a direct risk factor for bone fractures [4].
