What is osteoporosis?
- A condition involving a significant reduction in bone density, making bones weaker and prone to fractures.
What is osteopenia?
- A less severe decrease in bone density compared to osteoporosis.
How is osteoporosis diagnosed?
- Diagnosis is made using a T-score from a DEXA scan, with a T-score of less than -2.5 indicating osteoporosis.
What are the main risk factors for osteoporosis?
- Age, post-menopausal women, low BMI, low calcium and vitamin D intake, smoking, alcohol, and chronic diseases like rheumatoid arthritis.
Note not obesity
What is the T-score for osteoporosis on a DEXA scan?
- A T-score of less than -2.5 is diagnostic for osteoporosis.
What role does hormone replacement therapy (HRT) play in osteoporosis?
- HRT is protective against osteoporosis, especially in post-menopausal women.
What is the first-line treatment for osteoporosis?
- Bisphosphonates, such as alendronate, risedronate, or zoledronic acid.
What is the recommended calcium intake for osteoporosis management?
- At least 1000mg of calcium daily.
What is the recommended vitamin D intake for osteoporosis management?
- 400-800 IU of vitamin D daily.
What is the role of bisphosphonates in osteoporosis treatment?
- They reduce bone resorption by inhibiting osteoclast activity, helping to strengthen bones.
What are common side effects of bisphosphonates?
- Reflux, oesophageal erosions, atypical fractures, osteonecrosis of the jaw.
What is the management for patients on long-term corticosteroids?
- Bisphosphonates are recommended for patients on long-term steroids, and calcium and vitamin D supplementation.
How often should bisphosphonate treatment be reassessed?
- After 3-5 years, with a repeat DEXA scan to guide further treatment.
What is the FRAX tool used for?
- It is used to assess the 10-year fracture risk and guide decisions on DEXA scanning and treatment.
What are the key lifestyle modifications for managing osteoporosis?
- Increase physical activity, maintain a healthy weight, stop smoking, reduce alcohol consumption.
What age groups should be assessed for osteoporosis?
- All women over 65, all men over 75, and anyone over 50 with risk factors or previous fractures.
What is the role of a DEXA scan in osteoporosis diagnosis?
- DEXA scans measure bone mineral density and provide the T-score for diagnosis.
What is chondrocalcinosis?
- Calcification in cartilage, often seen on X-ray in conditions like Pseudogout, but not specifically in osteoporosis.
Why are falls a major concern in the elderly?
- Increased risk of fractures, hospitalisation, loss of independence, and mortality.
What are the common causes of falls in the elderly?
- Poor balance, muscle weakness, cognitive impairment, medications, environmental hazards, and vision problems.
Which 5 types of medications Should you check for when doing a falls assessment.
- Sedatives
- antihypertensives
- antidepressants
- antipsychotics
- opioids
What intrinsic factors contribute to falls?
- Age-related muscle loss, cognitive decline, sensory deficits, and chronic conditions (e.g., Parkinson’s, stroke).
What extrinsic factors contribute to falls?
- Slippery floors, poor lighting, loose rugs, clutter, and improper footwear.
How does vision impairment contribute to falls?
- Reduced depth perception, poor contrast sensitivity, and slower adaptation to light changes.
