What is the recommended management plan for a patient with osteopenia, with a 7.6% and 6.4% probability of major osteoporotic fractures and a 2.8% and 2% probability of hip fractures within the next 10 years?

Management of Osteopenia with Low Fracture Risk

This patient does not require pharmacological treatment at this time, as the FRAX scores (7.6% and 6.4% for major osteoporotic fracture; 2.8% and 2% for hip fracture) fall well below the National Osteoporosis Foundation treatment thresholds of ≥20% for major osteoporotic fracture and ≥3% for hip fracture. 1

Risk Stratification

Your patient falls into the low fracture risk category based on current evidence-based thresholds 1, 2:

• Major osteoporotic fracture risk: 7.6% and 6.4% (threshold for treatment: ≥20%) 1
• Hip fracture risk: 2.8% and 2% (threshold for treatment: ≥3%) 1, 2
• Diagnosis: Osteopenia (T-score between -1 and -2.5) without meeting treatment thresholds 1

The American College of Rheumatology defines low fracture risk as FRAX-adjusted 10-year risk of major osteoporotic fracture <10% and hip fracture <1%, with BMD >-1.0 3. While this patient's hip fracture risk slightly exceeds 1%, it remains well below the 3% treatment threshold established by the National Osteoporosis Foundation 1, 2.

Recommended Non-Pharmacological Management

Calcium and Vitamin D Supplementation

• Calcium: 1,000-1,200 mg daily through diet and/or supplements 3, 1
• Vitamin D: 600-800 IU daily, targeting serum levels ≥20 ng/mL 3, 1

Exercise Program

• Weight-bearing exercises and resistance training at least 3 times per week 1
• These activities directly reduce fracture risk independent of bone density changes 1

Lifestyle Modifications

• Smoking cessation if applicable 1
• Limit alcohol to 1-2 drinks per day maximum 1
• Maintain healthy weight in recommended range 1
• Fall prevention strategies including home safety assessment, balance training, and review of medications causing drowsiness or hypotension 1, 4

Monitoring Strategy

Bone Density Reassessment

• Repeat DXA scan in 2 years to assess for progression 1, 2
• Consider earlier reassessment (1 year) if new risk factors develop, such as initiation of glucocorticoid therapy, new fragility fracture, or significant weight loss 1, 5

Vertebral Fracture Assessment

• Include vertebral fracture assessment (VFA) or spinal x-ray with follow-up DXA to detect asymptomatic vertebral fractures 3, 2

Thresholds for Initiating Pharmacological Treatment

You should initiate pharmacological therapy if any of the following occur 1, 2:

• FRAX score increases to ≥20% for major osteoporotic fracture OR ≥3% for hip fracture 1, 2
• Any fragility fracture occurs (nontraumatic fracture of spine, hip, wrist, or humerus) 3, 1
• Bone density decreases to osteoporosis range (T-score ≤-2.5) 1
• Development of additional significant risk factors such as glucocorticoid therapy ≥2.5 mg/day prednisone equivalent 3

Glucocorticoid-Specific Considerations

If this patient initiates glucocorticoid therapy at doses >7.5 mg/day prednisone equivalent, manually adjust FRAX scores by multiplying major osteoporotic fracture risk by 1.15 and hip fracture risk by 1.2 3, 5. This adjustment would change the hip fracture risk from 2.8% to 3.36%, which would then meet treatment thresholds and warrant pharmacological intervention 3, 2.

Pharmacological Options When Treatment Becomes Indicated

If future reassessment indicates treatment is needed, oral bisphosphonates (alendronate or risedronate) are strongly recommended as first-line therapy for patients at high fracture risk 3, 6, 7:

• Bisphosphonates reduce vertebral fractures by 40-70%, nonvertebral fractures by 25-40%, and hip fractures by 40-53% 6
• For patients at very high risk (prior osteoporotic fracture, T-score ≤-3.5, or FRAX ≥30% for major osteoporotic fracture/≥4.5% for hip fracture), anabolic agents like teriparatide or romosozumab should be conditionally recommended over bisphosphonates 3, 2, 6
• Denosumab 60 mg subcutaneously every 6 months is an alternative that reduces vertebral fractures by 68% and hip fractures by 40% over 3 years 8

Common Pitfalls to Avoid

• Do not initiate pharmacological treatment based solely on osteopenia diagnosis without considering absolute fracture risk 1
• Do not use FRAX scores without considering glucocorticoid dose adjustments if the patient is on >7.5 mg/day prednisone 3, 5
• Do not neglect non-pharmacological interventions even in low-risk patients, as calcium, vitamin D, and exercise provide foundational fracture prevention 3, 1, 9
• Do not fail to reassess patients with progressive bone loss, as the 12.4% decrease in left hip BMD since 2009 warrants closer monitoring 1
