Every 3 seconds, someone in the world suffers an osteoporotic fracture. This startling statistic underscores the global impact of osteoporosis, a condition that affects millions of people worldwide. Osteoporosis, often dubbed the "silent thief," stealthily deteriorates bone strength without apparent symptoms until a fracture occurs. It disproportionately affects older adults, with one in three women and one in five men over 50 experiencing an osteoporotic fracture in their lifetime.

This article explores the latest treatment guidelines, exploring how new approaches in orthopedic care and osteoporosis management are reshaping patient outcomes and quality of life.

Understanding Osteoporosis and Bone Health

Osteoporosis develops gradually without symptoms until a fracture occurs and it results from an imbalance in the bone remodelling process, where bone breakdown outpaces bone formation. This leads to decreased bone density and a higher risk of fractures, particularly in the hip, spine, and wrist.

Maintaining bone health is crucial throughout life, but it becomes even more critical as we age. Factors influencing bone health include genetics, diet and nutrition, physical activity, hormonal changes, certain medications, and lifestyle factors such as smoking and excessive alcohol consumption.

Diagnosis and Assessment of Osteoporosis

The cornerstone of effective osteoporosis management is early diagnosis and accurate assessment of fracture risk. The latest guidelines recommend bone density testing using Dual-energy X-ray absorptiometry (DXA), which remains the gold standard for measuring bone mineral density (BMD). It's recommended for women aged 65 and older, men aged 70 and older, and younger adults with risk factors.

The FRAX tool, a WHO-developed algorithm, calculates the 10-year probability of major osteoporotic fractures, considering BMD and clinical risk factors. Additionally, Vertebral Fracture Assessment, an imaging technique, can identify existing vertebral fractures, which significantly increases the risk of future fractures.

Guidelines for Osteoporosis

Latest Treatment Guidelines for Osteoporosis

The primary goals of osteoporosis treatment are to prevent fractures, maintain or improve bone density, and enhance overall bone health. The latest guidelines emphasise a personalised approach to osteoporosis management, considering individual risk factors and patient preferences.

Lifestyle Modifications: The foundation of osteoporosis management includes regular weight-bearing and resistance exercises, adequate calcium and vitamin D intake, smoking cessation, limiting alcohol consumption, and implementing fall prevention strategies.
Pharmacological Interventions: Several medication classes are available for osteoporosis treatment, each with specific indications and considerations. Antiresorptive agents include bisphosphonates (e.g., alendronate, risedronate, zoledronic acid), denosumab (a RANKL inhibitor), and Selective Oestrogen Receptor Modulators (SERMs, e.g., raloxifene). Anabolic agents comprise teriparatide and abaloparatide (parathyroid hormone analogs) and romosozumab (sclerostin inhibitor). Hormone therapy, specifically oestrogen therapy for postmenopausal women with vasomotor symptoms, is also an option. The choice of medication depends on factors such as fracture risk, age, sex, and comorbidities. The latest guidelines suggest starting with an oral bisphosphonate for most patients due to its efficacy, safety, and cost-effectiveness. For patients at very high fracture risk or those who have failed other treatments, anabolic agents may be considered. Implementing sequential therapy (anabolic followed by antiresorptive) can provide optimal bone density improvement.
Duration of Therapy and Drug Holidays: The concept of bisphosphonate drug holidays has gained traction in recent years. For patients at moderate risk who have been on bisphosphonates for 3-5 years, a drug holiday may be considered. However, high-risk patients may benefit from continued therapy or switching to a different medication class.
Emerging Therapies: Research in osteoporosis treatments continues to evolve. Some promising areas include cathepsin K inhibitors, Src kinase inhibitors, anti-sclerostin antibodies, and gene therapies targeting bone metabolism.

Comprehensive Orthopaedic Care for Osteoporosis

Orthopaedic care plays a crucial role in managing osteoporosis, especially for patients who have already experienced fractures. The latest guidelines emphasise Fracture Liaison Services, which are coordinated care models ensuring that patients with fragility fractures receive appropriate evaluation, treatment, and follow-up.
Advanced surgical interventions for osteoporotic fractures, including minimally invasive procedures and bone cement augmentation, are part of the comprehensive care approach. Rehabilitation programmes featuring tailored physical therapy and exercise regimens are crucial to improve strength, balance, and mobility post-fracture.
Fall prevention is a key component of orthopaedic care for osteoporosis patients. This involves comprehensive assessment of fall risk and implementation of preventive strategies, including home safety evaluations and balance training.

Monitoring and Follow-up

Regular monitoring is essential to assess treatment efficacy and adjust management strategies. The guidelines recommend repeat DXA scans every 1-2 years, depending on initial bone density and treatment response. Annual height measurements are important to detect asymptomatic vertebral fractures. Periodic assessment of calcium and vitamin D levels, as well as monitoring of bone turnover markers in some cases, helps ensure optimal management.

Patient Education and Shared Decision-Making

Empowering patients through education is crucial for successful osteoporosis management. Healthcare providers should explain the nature of osteoporosis and its long-term implications. They should discuss treatment options, their benefits, and potential side effects with patients. Encouraging adherence to medication and lifestyle modifications is important, as is addressing patient concerns and preferences in treatment decisions.

Conclusion

Managing osteoporosis requires a multifaceted approach that combines lifestyle modifications, pharmacological interventions, and comprehensive orthopaedic care. The latest treatment guidelines emphasise personalised care, considering individual risk factors and patient preferences. As our understanding of bone health continues to evolve, so will our strategies for osteoporosis management. By staying informed about the latest developments and working closely with healthcare providers, individuals with osteoporosis can maintain their bone health, reduce fracture risk, and improve their overall quality of life.

FAQs About Managing Osteoporosis

Q. Can men get osteoporosis?
A. Yes, men can develop osteoporosis, especially after age 50, though it is more common in women. Risk factors include age, family history, and low testosterone.

Q. Is osteoporosis reversible?
A. While osteoporosis can't be fully reversed, its progression can be slowed or managed with medications, lifestyle changes, and adequate nutrition.

Q. What types of exercises are best for osteoporosis?
A. Weight-bearing exercises like walking, jogging, and resistance training are effective in strengthening bones and improving bone density.

Q. How much calcium and vitamin D do I need?
A. Adults need about 1,000-1,200 mg of calcium and 600-800 IU of vitamin D daily to maintain bone health and prevent osteoporosis.

Q. How does menopause affect osteoporosis risk?
A. Menopause increases osteoporosis risk due to the decline in oestrogen, a hormone that helps protect bone density. Hormone replacement therapy may be considered.
