What interventions reduce the risk of hip fractures in geriatric individuals with a history of osteoporosis or previous fractures?

Hip Fracture Prevention in Geriatric Patients with Osteoporosis

Pharmacological treatment with bisphosphonates (alendronate or risedronate) combined with calcium (1000-1200 mg/day) and vitamin D (800 IU/day) supplementation is the most effective intervention to reduce hip fractures in elderly osteoporotic patients, reducing subsequent fracture risk by approximately 50% over 3 years and hip fractures specifically by 40%. 1, 2

Primary Pharmacological Interventions

First-line therapy should use drugs proven to reduce vertebral, non-vertebral, AND hip fractures specifically:

• Bisphosphonates (alendronate or risedronate) are the preferred first-choice agents due to tolerability, low cost from generic availability, and extensive clinical experience 3
• Prescribe for 3-5 years initially, with longer duration for patients remaining at high risk 3
• Start treatment within the first 6 months post-fracture to maximize benefit during the period of highest subsequent fracture risk 4
• Regularly monitor for tolerance and adherence, as long-term compliance is often poor 1, 3

Alternative agents with proven hip fracture reduction:

• Denosumab 60 mg subcutaneously every 6 months reduced hip fractures by 40% (absolute risk reduction 0.3%) in postmenopausal women aged 60-91 years 5
• Zoledronic acid has demonstrated efficacy in reducing fracture risk specifically in frail patients with recent hip fracture 6
• Strontium ranelate is the first agent with documented anti-fracture efficacy for both non-vertebral and vertebral fractures in the oldest old (patients over 80) with sustained efficacy over 5 years 6

Essential Non-Pharmacological Interventions

Calcium and vitamin D supplementation is mandatory for all patients:

• Calcium 1000-1200 mg/day combined with vitamin D 800 IU/day reduces non-vertebral fractures by 15-20% and falls by 20% 2
• Many elderly patients, especially those in care institutions, have vitamin D inadequacy requiring supplementation 7
• Do not use high-pulse dosages of vitamin D, as these increase fall risk rather than prevent it 2

Comprehensive fall prevention program:

• Exercise programs involving high doses of exercise and incorporating balance training are effective in preventing fractures 7, 8
• Early postfracture introduction of physical training and muscle strengthening 1
• Long-term continuation of balance training and multidimensional fall prevention 1
• Reduce psychotropic medications that increase fall risk 8
• Assess and modify home hazards 9

Lifestyle modifications:

• Stop smoking and limit alcohol intake 1
• Ensure adequate nutritional status, as malnutrition is common in fracture patients 3

Implementation Strategy

Systematic evaluation is required for every patient aged 50+ with a fragility fracture:

• Review clinical risk factors for subsequent fractures 1
• Obtain DXA scanning of spine and hip to assess bone mineral density 1
• Perform imaging of the spine for vertebral fractures 1
• Evaluate falls risk through comprehensive assessment 1
• Identify secondary causes of osteoporosis 1

Multidisciplinary coordination:

• Requires a local responsible lead person/group that coordinates secondary fracture prevention based on guidelines 1
• Liaison between surgeons, rheumatologists/endocrinologists, geriatricians, and general practitioners 1
• Orthogeriatric comanagement should be provided, especially for elderly patients with hip fracture, to improve functional outcomes, reduce length of hospital stay, and reduce mortality 1

Patient Education

• Educate about disease burden, risk factors for fractures, follow-up requirements, and expected duration of therapy 1, 3
• Emphasize that fracture risk remains acutely elevated for 24 months before gradually declining 4

Critical Pitfalls to Avoid

• Do not wait for "perfect consolidation" to initiate osteoporosis therapy—start bisphosphonates immediately to avoid the osteoporosis care gap 4
• Do not delay fracture risk assessment and osteoporosis treatment in patients who have already sustained a fragility fracture, as this indicates high risk for subsequent fractures 3
• Avoid undertreatment: specific anti-osteoporosis drugs are underused, even in those most at risk of osteoporotic fracture 7
• Age should not be a barrier to intervention—senile osteoporosis is currently under-diagnosed and under-treated 6
• Do not rely solely on bone density improvement without addressing fall prevention, as falling is the strongest single risk factor for fracture in the elderly 8
