Osteoporosis Management Guidelines

Risk Assessment and Diagnosis

  • The American College of Rheumatology recommends using FRAX as the appropriate tool for assessing fracture risk and setting intervention thresholds in osteoporosis, with thresholds being age-dependent 2, 3
  • A female reference database should be used for the densitometric diagnosis of osteoporosis in men 3
  • Trabecular bone score, used with BMD and FRAX probability, provides useful information for fracture risk assessment 2, 4
  • All individuals with a prior fragility fracture should be considered for treatment with anti-osteoporosis medications 2, 3
  • Treatment regimens should be adapted to an individual's baseline fracture risk 2, 4

Non-Pharmacological Interventions

  • Ensuring vitamin D and calcium repletion is crucial, with recommended daily intake of 1,000-1,200 mg calcium and 800-1,000 IU vitamin D for men above 65 years 2, 5
  • Physical exercise, including balance training, flexibility exercises, endurance exercise, and resistance training, and a balanced diet should be recommended to all patients with osteoporosis 2, 5
  • Smoking cessation and limiting alcohol consumption should be actively encouraged 5

Pharmacological Management

  • Oral bisphosphonates, such as alendronate or risedronate, are recommended as first-line treatments for individuals at high risk of fracture 1, 2
  • Alendronate significantly improves BMD at the lumbar spine, total hip, and femoral neck 6
  • Risedronate improves BMD at the lumbar spine, total hip, and femoral neck 6
  • Denosumab or zoledronate are recommended as second-line treatments for individuals at high risk of fracture 1, 2
  • Zoledronate significantly improves lumbar spine BMD, femoral neck BMD, and total hip BMD 6, 7
  • Denosumab administered via 6-monthly subcutaneous injections improves BMD at the lumbar spine, femoral neck, and total hip 6
  • Sequential therapy starting with a bone-forming agent followed by an anti-resorptive agent should be considered for individuals at very high risk of fracture 1, 2
  • Abaloparatide is considered an appropriate first-line treatment for patients with osteoporosis at very high risk of osteoporotic fracture 1, 2
  • Teriparatide significantly improves BMD at the lumbar spine and femoral neck 7

Special Considerations

  • Serum total testosterone should be assessed as part of the pre-treatment assessment of men with osteoporosis 1, 8
  • Appropriate hormone replacement therapy should be considered in men with low levels of total or free serum testosterone 1, 8
  • Testosterone replacement has shown significant increases in lumbar spine trabecular volumetric BMD and cortical volumetric BMD 7
  • Patients with nonmetastatic cancer who are prescribed drugs that cause bone loss should be offered BMD testing every 2 years, or more frequently if medically necessary 5, 9
  • For cancer patients with osteoporosis or at increased risk of fractures, bone-modifying agents may be offered 5
  • Hormonal therapies for osteoporosis management are generally avoided in patients with hormonal-responsive cancers 5

Monitoring and Adherence

  • Biochemical markers of bone turnover are appropriate tools to assess adherence to anti-resorptive therapy 1, 2
  • Adherence can be monitored by measuring bone turnover markers at baseline and at 3 months 6
  • Poor adherence is a significant issue with oral bisphosphonates, with up to 64% of men being non-adherent by 12 months 3
