WEEK 6-Musculoskeletal Flashcards
(50 cards)
What is osteoporosis
A metabolic bone disease where bone resorption exceeds formation, leading to decreased bone density, porous bones and increased fracture risk
What causes osteoporosis at the cellular level
Imbalance between osteoclast (bone-resorbing) and osteblast (bone-building) activity, driven by hormones, cytokines and vitamin deficiencies
What are modifiable risk factors osteoporosis
smoking, alcohol use, low calcium/vitamin D intake, sedentary lifesttle, high caffeine or sodium and long-term corticosteroid use
What are non-midifiable risk factors for osteoporosis
Age>65, female sex, family history, endocrine disorders and post-menopausal status
What is DEXA scan and what does it measure?
A diagnostic test that measures bone mineral density (BMD), reported as a T-score to diagnose osteoporosis and fracture risk
What are complications of advanced osteoporosis
Pathological fractures (hip, vertebrae, wrist), kyphosis, height loss and chronic pain
What is degenerative disk disease (DDD)
age-related deterioration or herniation of spinal discs leading to pain, reduced mobility and nerve root compression
What are clinical manifestations of lumbar DDD
lower back pain, radiculopathy, reduced flexibility and muscle weakness
what conservative treatments are used for DDD
Physiotherapy, spinal bracing, core strengthening, NSAIDs, anglesics and antidepressants
When is surgery indicated for DDD
For severe pain or neurological deficits to conservative treatment
What is osteoarthritis (OA)
a degenerative joint disease caused by cartilage breakdown, leading to pain, stiffness and reduced mobilty
How does OA progress pathophysiologically
Cartilage becomes thin and brittle, osteophytes form, joint space narrows, and synovial inflammation can develop.
What are symptoms of OA?
Joint stiffness (especially in the morning), pain, crepitus, swelling, and asymmetry.
What joints are most commonly affected in OA?
Knees, hips, spine, and hands.
What is rheumatoid arthritis (RA)?
A chronic autoimmune disease causing systemic inflammation and symmetrical joint destruction.
What are early systemic signs of RA?
What are early systemic signs of RA?
What are early systemic signs of RA?
Small joints (hands, feet), and eventually larger joints (knees, elbows).
What is pannus in RA?
Inflammatory granulation tissue that invades and destroys cartilage and bone within joints.
What are common deformities in RA?
Swan neck, boutonnière, and ulnar deviation of the fingers.
Swan neck, boutonnière, and ulnar deviation of the fingers.
Disease-modifying anti-rheumatic drugs that slow progression of RA and PsA (e.g., methotrexate).
What is psoriatic arthritis (PsA)?
An inflammatory arthritis associated with psoriasis, involving skin, nails, and joints.
What are symptoms of PsA?
Joint pain, swelling, dactylitis (sausage digits), enthesitis, and nail changes like pitting.
What is gout?
A type of arthritis caused by excess uric acid leading to crystal deposits in joints.
What joint is commonly affected in gout?
The first metatarsophalangeal joint (big toe).
