Irrespective of their age, patients with recent fragility fracture have an increased risk of recurrence : this is the imminent fracture risk of multiple origins. As well the vertebral than the non-vertebral fractures are equally predictive of an increased and early fracture risk. Therefore, a fragility fracture is a strong signal for the clinicians to introduce a treatment against osteoporosis. Especially since most of the treatment have been shown to reduce quickly the incidence of fractures. To target easily patients with the highest risk of re-fractures would allow to improve our efficacy.
