MSK disorders Flashcards
What’s the difference between muscle sprain and muscle strain?
Sprain: Stretched or torn ligament
Strain: Stretched or torn muscle or tendon
RICE/ PRICE
Rest
Ice
Compression
Elevation
P- protection for further injury
what’s epicondylitis?
Epicondylitis is inflammation of a tendon where it attaches to bone
what’s tennis elbow?
lateral epicondylitis
what’s golfer’s elbow
medial epiconydlitis
do NOT use ___ therapy with bursitis because
do NOT use heat therapy
increase inflammation
Hyperuricemia and can lead to formation of _____ crystals in joints, bones & tissues
monosodium urate (MSU)
what causes gout?
defect in purine metabolism
what is gout flareup?
Innate immune response to deposition of MSU crystals
what happens during gout flareup?
Hyperplasia of synovial membrane
Cellular infiltration of neutrophils, proinflammatory cytokines (Interleukin IL1β)
Structural damage to joints
what are the 3 clinical stages of gout?
- asymptomatic
- acute gouty arthritis
- tophaceous gout
rhabdomylitis is the result of disintegration of ———————— muscle
striated muscle (skeletal muscle)
___ is leaked into the extracellular space during rhabdomylitis and can cause injury to ___ (organ)
myoglobin
injury to kidney
With muscle injury there is a leakage of _________ (ion) into _________space
extracellular Ca2+ into intracellular space
what drugs can cause rhabdomylitis
HMG-CoA reductase inhibitors (statins),
fibrates,
corticosteroids,
SSRIs
what’s the key focus in treating rhabdomylitis?
perserving renal function
what are the 3 types of osteoporosis?
Primary Type I: Postmenopausal women
Primary Type II: Senile (after age 70 years)
Secondary: Other etiologies or drugs as cause
The most common osteoporotic fracture are _______ because they are rich in ___ bone
vertebral fractures
spongy bone
what are the etiologies of osteoporosis?
- Decreased levels of estrogen & testosterone
- Inadequate levels of vitamin D, calcium, magnesium
- Alterations in OPG/RANKL/RANK system
- Postmenopausal osteoporosis:
↑osteoclast activity and changes in OPG - Glucocorticoids:
↑RANKL expression, inhibit OPG production by osteoblasts causing lower bone density
what types of drugs can cause osteoporosis?
glucocorticoids
SSRI
PPI
seizure medications: phenytoin (dilantin) and carbemazepine (tegretol)
Thyroid replacement
anticoagulant
immunosuppressant
What’s the Canadian guideline for BMD testing?
- All women & men ≥ 65 years
- Postmenopausal women & men age 50-64 yrs. with risk factors for fracture
- Young women or men (under age 50) with an existing disease associated with bone loss
after age of ___ bone density begins to decrease
30
what’s sarcopenia
Sarcopenia is age related loss of muscle mass & a decrease in muscle strength
Environmental factors that cause gout?
Increased intake of purine rich foods (seafood, red meat)
ETOH (beer), fructose-soft drinks
Increased BMI > 25 kg/m2 (hyperinsulinemia and reduced renal clearance of urate)
Drugs (i.e. diuretics, cyclosporin, beta-blockers, low dose ASA)
