Osteoporosis, Fibromyalgia, Vasculatides Flashcards
MC clinical presentation of osteoporosis
ASYMPTOMATIC
How else can osteoporosis present?
Fractures (vertebral, hip, pelvic)
Loss of height (d/t compression fractures)
According to USPSTF who needs to be screened for osteoporosis
Women, 65 years and older (grade B)
Women < 65 y/o, when fracture risk ≥ 65 y/o white woman with no additional risk factors (grade B)
Men, insufficient evidence for screening (grade I)
What tool is used to assess fracture risk for osteo?
FRAX tool
How does the FRAX tool work to assess risk for osteoporosis
Calculates 10-year risk for osteoporotic fractures in women < 65 y/o
Baseline risk = 65 y/o woman with no other risk factors
Compoenents assessed with the FRAX tool
Age Sex Weight Height Previous fracture Parent fractured hip Current smoking Glucocorticoids (chronic use of these) Rheumatoid arthritis Secondary osteoporosis Alcohol 3 or more units/day Femoral neck BMD (g/cm2)
GOLD standard for osteoporosis diagnosis
DEXA scan
T score < -2.5
What is a alternative fractures can be used to diagnose osteoporosis
Fragility fractures (from height level or below)
Spine Hip Wrist Humerus Rib pelvis
What labs can be used to determine osteoporosis
Chem panel (calcium, phosphorous, albumin, total protein, creatinine, liver enzymes including alkaline phosphatase, electrolytes)
25-hydroxyvitamin D (25[OH]D)
CBC
Non pharmacologic methods to manage osteoporosis?
***EXERCISE Diet Avoid corticosteroids Tobacco cessation Avoid excessive alcohol intake Fall prevention measures No need to memorize ***most effective
What amount of Vitamin D and calcium should be used to manage osteoporosis?
Vitamin D = 600-800
Calcium = 1000 mg (all adults) 1200 MG (postmenopausal women, men>70 y/o)

DEXA every 5 years
How do you monitor osteoporosis in someone with a T score -1.5 to -2.0:
3-5 years
How do you monitor osteoporosis in someone with a T score < -2.0
every 1-2 years
