In a case with spinal osteoporosis T-score -2.7 and FRAX major fracture risk 8% and hip risk 2%, how should you interpret treatment need?

• A. FRAX risk alone justifies treatment, regardless of T-score.
• B. Treat only if hip fracture risk exceeds 3%.
• C. With a T-score of -2.7, treat only after a vertebral fracture.
• D. Osteoporosis by BMD; FRAX risk might be reasonable; treatment indicated given T-score and fracture risk; spine fracture risk supports therapy.

Answer: (D)

The key idea is that treatment decisions for osteoporosis consider both the bone density category and the estimated fracture risk. A T-score of −2.7 places the patient in the osteoporosis range by BMD criteria, which by itself supports starting anti-osteoporosis therapy. The FRAX estimate adds context: an 8% 10-year risk of a major osteoporotic fracture and a 2% risk of hip fracture indicate a meaningful overall fracture risk, reinforcing the need for treatment. The fact that spine fracture risk is involved further strengthens the case, since vertebral fragility is a strong predictor of future fractures and often guides the urgency and choice of therapy. Together, osteoporosis by BMD plus the notable fracture risk justify initiating treatment, and spine-related risk supports that decision.
