Major Risk Factors for Osteoporosis in Caucasian postmenopausal women:
History of fragility fracture in direct relatives
Personal history of fracture as an adult
Low body weight (less than a 127 lbs)
Use of oral corticosteroid therapy for more than 3 months
Current smoker
Additional Risk Factors:
Recent falls
Impaired vision
Dementia
Poor health/frailty
Lifelong low calcium intake
Low physical activity
Estrogen deficiency at an early age (45 yrs or less)
Alcohol in amounts greater than 2 drinks a day
Osteoporosis is a systemic skeletal disease. It’s hallmarks are
low bone mass and deterioration of the micro architecture of bone.
People who suffer with the osteoporosis are more susceptible to
fractures. Bone mass usually peaks between the ages of 30 to 35
and declines steadily thereafter. Loss of bone mass in women is
accelerated after menopause. Women are four times more likely to
develop osteoporosis as are men.
In the United States each year there are over 250,000 hip
fractures, more than 250,000 wrist fractures and over 700,000
spinal fractures. Most of these are attributed to osteoporosis.
Of all the individuals who suffer a hip fracture, approximately one
half will be permanently disabled, almost 20% will require long
term nursing care and up to 24% will die within one year after
their hip fracture. In fact, hip fractures are responsible for
approximately 65,000 deaths per year in the United States alone.
The cost of fractures in the U. S. Healthcare System is staggering.
Fractures account for 13.8 billion dollars per year, more than the
cost for congestive heart failure or asthma. As the average age of
the American population continues to increase, so will the cost
related to low bone mass (osteoporosis) and concomitant fractures.
In fact, it is predicted that the cost will double over the next 30
years.
DESCRIPTION OF OSTEOPOROSIS
Bone is constantly being resorbed and replaced with new bone. This
dynamic process is called remodeling. This is necessary for normal
development and maintenance of a healthy skeleton.
In young adults, bone is removed by osteoclasts (bone removing
cells). This bone is completely replaced by osteoblasts (bone
producing cells). Women after menopause have an accelerated bone
loss. The osteoclasts create a larger number of cavities which
cannot be completely refilled by the osteoblasts. Therefore, the
amount of bone mass in the skeleton decreases and the skeleton
becomes weak, therefore making a patient with osteoporosis more
susceptible to fractures.
WHO IS AT RISK FOR OSTEOPOROSIS
All women over the age of 50 are at risk for osteoporosis. In
fact, one study from the osteoporosis registry showed that 34% of
women over the age of 50 have osteoporosis. The same study showed
51% of women in their 60's have osteoporosis, 72% women in their
70's have osteoporosis and 83% of women in their 80's suffer from
the disease of osteoporosis.
Another study involving osteoporosis showed only 5% of patients
with osteoporosis were correctly diagnosed and treated, 5% of
patients were diagnosed with osteoporosis but were not getting
treatment, 12% of the patients had classic signs and symptoms of
osteoporosis but were not being treated. The same study showed
approximately 78% of patients who were at risk for osteoporosis
were not properly diagnosed.
Here at South Carolina Sports Medicine, we have incorporated the
state of art DEXA machine (dual/energy x-ray absorptiometry) which
is the most accurate and precise method of detecting osteoporosis
today.

Bone Health:
Bone loss leads to an increased risk of fracture that is
magnified by other aging-associated changes. Osteoporosis is preventable
and treatable, but because there are no warning signs until a fracture occurs,
many people are not being diagnosed in time to receive effective therapy
during the early phase of the disease.
