28
Q

A

the pateint’s waist circumference (wasist just above the hip bones)

Patiente may have excess body fat if waist circumference is

> 35 for women

> 40 for men

28
Q

What aprat of the lower back is the most vulnerable?

A

L5-S1, where sacral vertebrae take a sharp posterior angle

29
Q

What precent of the population experiences low back pain at lest onece in a lifetime

60-80%

30
Q

how many american’s have osteoporosis?

A

10 million and 34 million are at increased risk

31
Q

waht percent of men are at risk for osteoporosis?

A

42% of those at risk are men

32
Q

What does bone strength reflect?

A

both BONE DENSITY and BONE QUALITY

33
Q

what is bone density?

A

determined by the interaction of bone mass (highest in send decade) , new bone formaiton, and bone resorption or loss

34
Q

what is bone quality?

A

architecture, turnover, damage accumulation from microfratures and mineralization

35
Q

whawt is osteoporosis?

A

skeletal disoder characterized by compromised bone strength predisposing a person to an increased risk of fracture

36
Q

How is bone strength measured?

A

there is no direct measuremten of bone strength

bone mineral density, which accounts for approx 70% bone strenght, is used to proxy meausre

37
Q

What is Osteopenia

A

Bone density 1.0-2.5 standard deviations below mean for young adult white women (T score between -2.5 and -1.0)

38
Q

Wht is Osteoporosis?

A

Bone density 1.0-2.5 or more standard deviations below the mean for young adult white woment (T score less tahn -2.5)

39
Q

what part of body is bone density measured?

A

1 hip, femoral neck, Ward’s triagnle at the femoral neck, greater trochanater, an dtotal hip

40
Q

What is a 10% drop in bone density, equivaletn to in fractures?

A

10% drop in bone density is 1.0 standard devtiatino, is ass. with 20% increase risk for fracture

41
Q

What are basic screening questinos for older women?

A 
Have you ever had a fracture
Did either parent ever have a fracture?
Do you smoke?

Have you ever taken estrogen replacement therapy?
42
Q

Family Hx of fracture in a first degree relative
Hx of fracture
Higher intakes of alcohol
Women with delayed menarche or early menopause
current smokers
low levels of 25 hydroxyvitamin D
Use of corticosteroids for more than2 months
Inflammatory disorders of MC, pulmoanry or gasstrointestinal systems, including celiac sprue, chrhonic renal disease, organ tranplantaiotn, hypognoadism, anorexia nervosa

43
Q

What are some therapeutic uses of avaialbe agents for treating osteoporosis?

A

increase clacium intake to reduce age-related hyperparathyroidism and increase minearlization of newly formed bone

2/3 of patients with hip fractures are deficient in Vitamin D (for Ca absorption and muscle strength)

antiresportpive agents

anabolic agents such as parathyroid hormone stimulate bond formation by acting priamrly on osteoblasts
