Osteoporosis
By Jody Vulk PA-C
Northwest Iowa Bone, Joint
& Sports Surgeons
Osteoporosis
“Porous bone“
Bones lose protein & mineral content
Clinical Definitions of OP
Vertebral height loss of > 25% of the
vertebral body
2 compression fractures
2 or more fragility fractures
FRAGILITY FRACTURES

A fracture from forces that
would not ordinarily cause
fracture in a healthy young
adult.

Quantified as forces equivalent
to a fall from a standing height
or less.
Types of Fragility Fractures

Compression Fractures of the Vertebra


Proximal Humerus
Distal Radius Fractures

Hip Fractures
True or False
Most Common Fragility Fractures are:
#1 Spine
#2 Wrist
#3 Hip
True
Spine 27%
Wrist 19%
Hip 14%
Bone Cells
Osteoclasts
■
■
Remove or retire old
bone.
Active throughout
lifetime.
Osteoblasts
■
■
Create new bone
Best before age 35 &
before menopause
Osteoclasts
Osteoblasts
Remove Old Bone
(Classic)
Create new bone
(having a Blast!)
In Osteoporosis
More of these working…
than these.

Dual Energy X-ray Absorptiometry
BMD Levels
Normal = 0 to 0.9 T-Score
Osteopenia = 1 to -2.4 TScore
Osteoporosis =
-2.5 T-Score
Who needs a BMD?

A woman nearing menopause
(for baseline)

Men over the age of 70

Women 65 or older
(& have never had one)

Those with risk factors for osteoporosis
How often to Test

Normal BMD=15 years

Osteopenia=5 years

Severe Osteopenia=1 year

85 or older=3 years

True or False
To avoid
Osteoporosis--

Osteoporosis & Vitamin D
Deficiency
1
 1/3
Billion worldwide
of OP patients also Vitamin D
deficient
 Vitamin
D deficiency is not age
dependent.
Vitamin D is created through the skin by exposure
to sunlight
Vitamin D and Sunlight
You must live near the equator to rely on its benefits.
True or False
Caucasians are more prone to Vitamin D
deficiencies than those with darker skin.
False
Darker skin does
not absorb
Vitamin D as well.
Vitamin D Rich foods
Fatty fish
*Cod Liver oil(1360 IU)
Swordfish(566 IU)
Salmon(sockeye)(447 IU)
Tuna(154 IU)
Fortified foods:
Milk (115 IU)
Orange juice
(137 IU)
*avoid Cod liver oil
Egg yolks (41 IU).

Adults < 50
Adults > 50
*800 to 1,000 IU daily
Normal Vitamin D level, do not exceed 4,000IU
daily.
*Do not commit these to long term
memory, follow-up research
pending.
Vitamin D Deficiency Risk Factors
Risk Factors of Vitamin D deficiency


Northern Latitudes

<15 minutes of sun
African American, or dark skinned


Elderly
Obesity
Vitamin D

Vitamin D is fat soluble, stored in fat
Testing is on blood
Loose weight, boost Vitamin D


Who is at risk?
True or False
Men do not need to be tested for Osteoporosis.
False


2 million men have
OP
Men are more likely
to die in the first year
after hip fracture.

Men who fracture
are less likely to be
tested.
Early Signs of Osteoporosis
Joan Surber

Age 68

Pelvic Fracture
1/28/2012

T-Score of -2.5 in
her Lumbar Spine, 1.8 in the Right hip
and a -2.2 in the
Left hip.

Vitamin
D=12ng/mL
Severe Osteoporosis
T-score –2.5 or less
&
a fragility fracture has occurred.
Leg braces as a child
Calcaneus Fracture at
age 42
Menopause at age
34
20+ year history of
GERD with medication
use
Risks factors & Prevention
Heredity/Ethnicity
Don’t have it in your genes
Hormonal Changes
(Estrogen & Testosterone)
Hormone replacement (at
the guidance of your PCP)
Aging
Not recommending to avoid
this one.
Pharmaceuticals
Avoid long-term use of bone
depleting medications
(Cont.) Risk Factors & Prevention
Low BMI
History of
Fracture
EAT! -a diet rich in
colors and eat real
foods!
Bubble wrap
(Cont.) Risk Factors & Prevention
Malabsorption
Poor Diet
Smoking
Alcohol in excess
Lack of Exercise
Avoid Gastric Bypass, Celiac
Sprue, Anorexia…
Eat FOODs rich in Vitamins
and minerals
Don’t do that!
Limit alcohol to no more than
2 beverages daily
Weight bearing exercises such
as walking, tia chi, & weight
lifting/resistance exercises
Types of Osteoporosis
Primary
Secondary
Relatively unknown
cause other than
advancing age
and
postmenopausal
Has a known cause
or reason for having
developed (i.e.=oral
corticosteroid use,
other medications,
diseases or
conditions)
True or False
Kyphosis of the spine is “normal for aging.”
False
Decreasing height and humped back are
not normal. They are indications of
compression fractures.
