Osteoporosis is a major public health problem. Its screening and its treatment remain largely insufficient while therapies have demonstrated their effectiveness. In the event of a severe fracture, the update of the 2016/2017 recommendations, prepared by the Research and Information Group on Osteoporosis and the French Rheumatology Society, concerning osteoporosis recommends a specific treatment with bisphosphonates as first-line treatment, without bone densitometry, regardless of age. The frequency of prescribing anti-osteoporotic treatment as an outpatient after a fracture of the upper extremity of the femur is very low (2% to 21% according to the studies). The main factors associated with non-prescription found are co-morbidities (charlson score> 6), dementia, obesity (BMI> 30), chronic alcoholism, male sex, polypharmacy> 4, age. Conversely, the factors associated with prescribing are recurrent falls (> 2 / year), a history of osteoporotic fracture, an Iso Resource Group> 3, female sex, and corticosteroid therapy.

1. / The collection of patients' characteristics upon admission will be based on the computerized patient file and the paper file: socio-demographic data, co-morbidities, functional status, entry / exit treatments, place of residence, source, balance sheet hospital.
2. / Determination with the treating doctor or the pharmacist of the prescriptions of the anti-osteoporotic treatments at 6 months of the hospital care.
3. / Research factors associated with the prescription (or non-prescription) of anti-osteoporotic treatments.
