Fracture risk categorization.

Fracture risk	Criteria
Low risk	All of the following criteria -No previous fragility fracture -T-score ≥ −1.0a -A 10-year probability of hip fracture < 3%b
Moderate risk	All of the following criteria -No previous fragility fracture -T-score between −1.0 and −2.5a -A 10-year probability of hip fracture < 3%b
High risk	One of the following criteria -A fragility vertebral or hip fracture -T-score ≤ −2.5a -T-score between −1.0 and −2.5 and a 10-year probability of hip fracture ≥ 3%b -T-score between −1.0 and −2.5 and a fragility fracture of the proximal humerus, pelvis, or distal forearm
Very high risk	One of the following criteria -Fragility vertebral or hip fracture within 12 months in patients ≥ 65 years with T-score ≤ −2.5 (IIa, B) -Recurrent vertebral fracture or vertebral fractures ≥ 2 levels with moderate to severe deformity (IIa, B) -Bilateral hip fractures, hip and vertebral fractures, or multiple fractures (≥ 3 times or ≥ 3 sites) (IIa, B) -Fragility fracture while on osteoporosis therapy for ≥ 2 years and no secondary cause of osteoporosis (IIa, B) -T-score ≤ −3.5 in women ≥ 65 years or men ≥ 70 years (IIb, D)
