[Locomotive syndrome and frailty. Osteoporosis as an underlying disorder in the locomotive syndrome].

Osteoporosis, a disorder related to locomotive syndrome, has been nicknamed "the silent disease" since it has no symptoms until fragility fracture occurs. However, a new fragility fracture cannot only reduce daily activity but can also increase fracture risk resulting in possible repetition of the fracture or other new fractures. As a result, daily living activities requiring mobility are often rapidly reduced and the quality of life can be considerably impaired. There are three strategies for preventing fragility fractures : prevention of falls, anti-osteoporosis treatment and hip protectors. A multidisciplinary approach including these strategies should be emphasized to impede the damaging process involved in fragility fracture.
