Are women more susceptible to some injuries
Yes, because of a woman's biological and physiological make up women are
more prone to some types of injuries than men. For example, the rate of hip
fracture is two to three times higher in women than men, women experience
nearly two-thirds of all work related carpal tunnel syndrome and repetitive
stress injuries, and women are four to six times more likely to suffer serious
knee injuries than men. Following are articles describing these issues and ways
to prevent each from occurring.
Carpal tunnel syndrome: What is it and how can
it affect you?
The carpal tunnel is the tunnel-like structure formed by the carpal bones
and tendons in the wrist that provides the pathway for the median nerve to send
nerve impulses to the fingers and base of the thumb. When the tendons become
inflamed, they put pressure on the median nerve and carpal tunnel syndrome
Carpal tunnel syndrome is more common in women, especially after age 30, and
is most often caused by repetitive and forceful movements of the wrist during
work and leisure activities. According to the U.S. Bureau of Labor Statistics,
"disorders associated with repeated trauma" account for 60 percent of
all occupational illnesses and, of these disorders, carpal tunnel syndrome is
the most frequently reported. With an average case of carpal tunnel syndrome,
30 days of work are lost, accounting for the highest number of work days lost,
of all major work- related injuries.
Symptoms of carpal tunnel
- Numbness or tingling in your hand and fingers, especially the thumb, index
and middle fingers
- Pain in your wrist, palm or forearm
- More numbness or pain at night than during the day. The pain may be so bad
that it wakes you up.
- More pain when you use your hand or wrist more.
- Trouble gripping objects.
- Weakness in your thumb.
Who is most at risk for carpal tunnel
Since carpal tunnel syndrome is associated with repetitive motions of the
hand and wrist, it is most commonly found in those with jobs requiring
repetitive motions such as computer operators, carpenters, grocery checkers,
assembly-line workers, meat packers, violinists and mechanics. Hobbies such as
gardening, needlework, golfing or canoeing can also bring on the symptoms of
carpal tunnel syndrome.
In most cases, an accurate medical history and clinical examination will
establish the diagnosis. During a clinical exam, your doctor may test for
symptoms using Phalen's test (bending the wrist firmly palmward for 60 seconds
to duplicate symptoms) or by tapping the front of the wrist over the nerve
(Tinel's sign). For questionable diagnoses, a nerve conduction or
electromyography test (EMG) may be conducted, though these are more
uncomfortable and expensive.
Non-operative treatment may be attempted for patients with recent, mild or
intermittent symptoms. It includes the use of anti-inflammatory drugs and night
splints to prevent wrist flexion. However, most cases will recur if the
underlying cause of the nerve compression continues. Unless significant
improvement is noted early in such treatment, surgical treatment may be
In most cases of carpal tunnel syndrome, either traditional open surgery or
endoscopic surgery, where a telescope is used to visualize the nerve and
transverse ligament, will provide permanent relief for 80 percent to 90 percent
Surgery is performed by cutting the transverse carpal ligament that forms
the roof of the carpal tunnel to relieve pressure on the median nerve. The
surgery is performed at an outpatient facility and full recovery usually occurs
over several weeks to a few months.
In some cases, where the nerve has been permanently damaged, surgery will
not completely relieve the pain associated with carpal tunnel syndrome.
Therefore, it is important to take the measures necessary to prevent the onset
or worsening of carpal tunnel syndrome.
Carpal tunnel syndrome occurs most often in workers whose motions are not
only repetitious, but are continued for hours at a time. Here are some
suggestions that may help prevent carpal tunnel syndrome:
- Lose weight if you are overweight.
- Get treatment for any underlying disease that may be causing carpal tunnel
- If you do the same tasks with your hands over and over, try not to bend,
extend or twist your hands for long periods of time.
- Don't work with your arms too close or too far from your body.
- Don't rest your wrists on hard surfaces for long periods of time.
- Switch hands during work tasks.
- Make sure the tools you use are not too big for your hands.
- Take regular breaks from repeated hand movements to give your hands and
wrists a rest every 10-15 minutes each hour.
- Don't sit or stand in the same position all day.
- If you use a keyboard, adjust the height of your chair so that your
forearms are level with the keyboard and you don't have to flex your wrists to
type. (there should be a 90 degree angle between your upper arm and forearm, as
well as your thigh and torso)
Exercises like the following can also
A. Make tight fists, holding for one second, then release and stretch your
fingers wide. Hold for five seconds. Repeat several times.
B. Stretch your arms out in front of you. Raise and lower them in
outstretched position several times. Next, rotate your hands 10 times by making
circles in the air with your fingertips.

Did You Know...
In Illinois, there are approximately 6,000 deaths from unintentional
injuries annually; they are the leading cause of death for ages 1-34.
Unintentional injuries are those that are accidental and include such things as
motor vehicle crashes, poisoning, falls, suffocation and burns. In addition,
unintentional injuries often cause disabilities that greatly decrease a
person's quality of life and productivity.
Motor vehicle injury accounts for the greatest number of fatalities among
all unintentional injury causes. Though the rate of motor vehicle deaths
in women (10.1 per 100,000) is less than half that of men (21.9 per
100,000) nationally, it still accounts for the greatest number of unintentional
injury deaths in women. Top causes of unintentional injury deaths in U.S. women
are shown in the chart to the right.

Women Have More Sport and Exercise Related
Injuries than Men
The benefits of exercise are many, from decreasing the risk of heart disease
and stroke to reducing stress and helping us feel energized. However, though
seldom mentioned, exercise-related injuries can occur if the proper precautions
are not taken, especially for women.
Studies show that injuries are common among those who exercise or are
involved in sports and women have even higher rates of sport and
exercise-related injury than men. For instance, injuries among women going
through basic military training are approximately twice those experienced by
men; women's risk for serious injury is 2.5 times greater than for men.1 Though
studies of the effects of exercise in the military are not exactly the same as
studying the effects of injury in the civilian population, they often shed
light on issues that do occur in the civilian population.
Since Title IX went into effect in 1972 preventing sex discrimination in
educational settings, the number of high school girls in sports has grown from
approximately 300,000 in the early 1970s to 2.7 million (an 800 percent
increase). That amounts to about one in three high school girls playing
sports.2 The number at the college level is also increasing. Likewise, many
women begin exercise programs for health reasons and to improve their
appearance, though they may not be involved in competitive sports.
What do the studies reveal and what are the
risk factors for exercise-related injury?
Recent studies now indicate that a person's current level of physical
fitness is one of the most important predictors of exercise-related injury.
During military basic training, low levels of aerobic fitness and low muscular
endurance have been consistently associated with injury risk. Although
women going through basic training experienced twice as many injuries as men,
when aerobic fitness level is controlled for in studies, this difference
diminishes to almost zero.
Therefore, the difference in injury rates between the sexes may be more a
result of lack of physical fitness than actual gender differences.3 Although
such studies have not been conducted in the civilian population, these findings
imply that lack of aerobic fitness may also be a leading risk factor for
exercise-related injuries among civilians.
Recommendations for Prevention4
Based on the above findings, recommendations for prevention of
exercise-related injuries include the following:
- Be realistic when setting exercise goals.
- Tailor exercise to accommodate your current level of fitness and increase
frequency, duration and intensity gradually.
- Use a 10 percent rule. Increase training by 10 percent increments. Women
who have been sedentary and are just beginning an exercise program should start
with five to ten minutes of light-intensity exercise and gradually increase to
the desired level of intensity or duration.
- If you are over age 50 or if you have a chronic disease or risk of a
chronic disease, consult your physician to ensure that your exercise program is
- Encourage your daughters to play sports and to start exercising regularly
at a young age to gain a high level of fitness to protect them against future
injury. If a girl does not get involved in sports by the time she is 10, there
is less than a 10 percent chance that she will be involved in sports when she
- Be aware of early signs of potential injury. Increasing muscle soreness,
bone and joint pain, excessive fatigue and performance decreases are signals
that the body needs to rest. Trainers and coaches should also be aware of these
signs. When any of the signs are present, incrementally decrease the frequency,
duration or intensity until the signs are no longer present. In some cases, it
may be necessary to stop the activity for a time so that the injury can heal
- If possible, ask a trainer or coach to assess the level of intensity at
which you should exercise to gain the most from the exercise without
injury. Once you know the heart rate at which you should exercise, check it
frequently to see if you are exercising at the proper level. A good rule of
thumb is that you should be able to talk while you exercise. If this is not
possible, you are probably exercising too hard.
- If injured, allow sufficient recovery and rehabilitation time to prevent
Remember, exercise keeps you healthy in so many ways, preventing
cardiovascular disease, stroke, diabetes and cancer, as well as being great for
your mental and emotional well-being. You need to keep yourself injury free so
that you can continue exercising to reap all these benefits. One of the surest
ways to prevent injury while exercising is by keeping a high level of fitness.
In addition to following the prevention guidelines above, this will involve
encouraging your daughters to begin exercising as early as possible and to
continue to exercise regularly throughout life.

Osteoporosis Causes Fractures in One out of Every Two Women
(Compiled and adapted from articles of the National Osteoporosis Foundation,
2001; National Institutes of Health, U.S. Preventive Services Task Force, 1996;
and Illinois Department of Public Health, 1992-1995 data)
One of every two women will suffer from osteoporosis in her lifetime.
Osteoporosis leads to bone fragility and an increased risk of fracture of the
hip, spine and wrist. Hip fracture is the most serious consequence of
osteoporosis, affecting 15 percent of women. These fractures are an important
health care concern for several reasons:
- 300,000 Americans age 45 and over are admitted to hospitals with hip
fractures each year and hip fractures are the second leading cause of nursing
home admissions. Osteoporosis was the underlying cause of most of these hip
fractures. Hospitalization rates for hip fractures in Illinois are 10 percent
to 20 percent higher than the national average. By 1995, hospitalization costs
for osteoporosis in Illinois had reached $243 million, an increase of 13
percent since 1992.
- 24 percent of hip fracture patients age 50 and over die in the year
following their fracture.
- Only one-third fully regain their pre-fracture level of independence.
- Even after one year, more than 40 percent of patients still cannot walk
Women and Hip Fracture
The rate of hip fracture is two to three times higher in women than in men.
Approximately 90 percent of hip fractures can be attributed to osteoporosis in
white women age 65 and older. For women age 85 and older, 95 percent of hip
fractures can be attributed to osteoporosis.1 Other populations also are at
significant risk, but the attributions are slightly lower than for whites.
A woman's risk of hip fracture is equal to her combined risk of breast,
uterine and ovarian cancer.
Osteoporosis is diagnosed through a bone mineral density test (BMD), which
determines risk for future fracture. A BMD measures the density of your bones
(bone mass) and is necessary to help determine whether medication is needed to
help maintain bone mass, prevent further bone loss and reduce fracture risk.
The BMD test is accurate, painless and noninvasive. Since osteoporosis can
develop undetected for decades until a fracture occurs, early diagnosis is
important for anyone with any of the following risk factors.
What puts a woman at risk for osteoporotic
- Personal history of adult fracture or history of fracture in a first-degree
- Caucasian or Asian race*
- Advanced age
- Current cigarette smoking
- Low body weight (< 127 lbs)
- Estrogen deficiency:
- --Early menopause (< age 45)
- --More than one year without menstruation (during childbearing years)
- Low calcium intake (lifelong)
- Impaired eyesight despite adequate correction
- Recurrent falls
- Inadequate physical activity
- Poor health/frailty
* Note: While Caucasians and Asians appear to be at highest risk, risks for
those of other races or ethnicities can still be substantial.
Calcium is needed for the heart, muscles and nerves to function properly and
for blood to clot. Inadequate calcium is thought to contribute to the
development of osteoporosis. National nutrition surveys have shown that many
women and young girls consume less than half the amount of calcium recommended
to grow and maintain healthy bones.

Source for Recommended Calcium Intakes: Perspectives in Nutrition, by Gordon
M. Wardlaw (WCB McGraw-Hill,1999)
Source for Foods Rich in Calcium: Adapted from National Osteoporosis
If you have difficulty getting enough calcium from the foods you eat, you
may take a calcium supplement to make up the difference.
Vitamin D is needed for the body to absorb calcium. Without enough vitamin
D, you will be unable to absorb calcium from the foods you eat, and your body
will have to take calcium from your bones. Vitamin D comes from two sources:
through the skin following direct exposure to sunlight and from the diet.
Experts recommend a daily intake between 400 and 800 IU per day, which also can
be obtained from fortified dairy products, egg yolks, saltwater fish and liver.
Exercise is also important to maintaining bone health. If you exercise
regularly in childhood and adolescence, you are more likely to reach a greater
peak bone density than those who are inactive. The best exercise for your bones
is weight-bearing exercise such as walking, dancing, jogging, stair- climbing,
racquet sports and hiking. If you have been sedentary most of your adult life,
be sure to check with your health care provider before beginning any exercise
Medications for Prevention and Treatment
Although there is no cure for osteoporosis, five medications are approved by
the U.S. Food and Drug Administration (FDA) for prevention and/or treatment of
osteoporosis. Each of these medications slows or stops bone loss, increases
bone density and reduces fracture risk.
Drugs to Prevent Osteoporosis Drugs to
- Estrogen/hormone replacement therapy ERT/HRT ERT/HRT
- Alendronate Calcitonin
- Raloxifene Raloxifene
- Risidronate Alendronate (when glucocorticoid-induced)
- Risidronate (when glucocorticoid-induced)
These medications affect the bone remodeling cycle and are classified as
anti-resorptive medications. Bone remodeling consists of two distinct stages:
bone resorption and bone formation. During resorption, special cells on the
bone's surface dissolve bone tissue and create small cavities. During
formation, other cells fill the cavities with new bone tissue. Usually, bone
resorption and bone formation are linked so that they occur in close sequence
and remain balanced. When osteoporosis is present, the balance is altered and
bone loss occurs. Anti-resorptive medications slow or stop the bone resorbing
portion of the bone-remodeling cycle but do not slow the bone-forming portion
of the cycle. As a result, decreases in bone density are slowed and in some
cases bone density may even increase.
Importance of Rehabilitation and Fall
It is very important that people recovering from a fracture receive
rehabilitation to improve muscle strength and coordination to help prevent
future falls and fractures. Fractures of the hip often change a person's gait,
and vertebral fractures can cause postural changes. Unfortunately, these
consequences of fracture can further increase the risk of falls and more
fractures, so rehabilitation is vital, as well as instruction in safe movement.
See your doctor for more information on ways to prevent falls. In addition, the
home should be fall-proofed and common household hazards such as slippery
floors, scatter rugs and unlit stairways should be addressed. The National
Osteoporosis Foundation is drafting a rehabilitation guide for physicians and
publishes a booklet on fall prevention, Falls and Related Fractures, with tips
on fall-proofing the home. For more information about osteoporosis and hip
fracture, visit http://www.nof.org/osteoporosis/ .

materials, can be ordered on-line.

Kids Switched to Seat Belts Too
Many parents are moving young children into seat belts too soon after they
outgrow child safety seats. By doing so, parents are putting their children at
a higher risk of serious injury in crashes, according to the first research
into the subject. Young children who are buckled prematurely into adult seat
belts that are not designed to fit them properly, are 3 « times more
likely to suffer a significant injury and four times more likely to have
serious head injuries in crashes than children who are properly restrained with
booster or car seats. Proper restraint means using infant and convertible child
safety seats for children younger than 4 and booster seats for children from 4
until about 9, when they fit properly in the vehicle seat belt. As explained by
Dr. Dennis Durbin, co-author of the study highlighted in a recent Chicago
Tribune article, "This research provides strong evidence that belt-
positioning booster seats are a crucial safety step between car seats and adult
A Growing Public Health Concern: Motor Vehicle-Related Injuries Among Older
Adults As highlighted in a recent issue of the Morbidity and Mortality Weekly
Report, researchers from CDC's National Center for Injury Prevention and
Control gave a summary of 1990-1997 surveillance data from the National Highway
Traffic Safety Administration on motor vehicle-related injuries and fatalities
among older adults defined as adults 65 years and older. Results of the study
showed that there was a 14 percent increase in the number of motor vehicle
traffic-related fatalities and a 19 percent increase in the number of motor
vehicle traffic-related nonfatal injuries between 1990 and 1997 among older
adults. During the eight-year study period, traffic crashes accounted for
approximately 55,000 deaths and 1,869,308 nonfatal injuries among older adults.
In 1996, older adults represented 13 percent of the U.S. population and
accounted for 17 percent of all motor vehicle-related deaths. Likewise, the
female death rate from motor vehicle-related injuries rises sharply from 9.5
per 100,000 deaths in those 45-64 to 17.6 per 100,000 in the 65 and older age
group. Possible reasons for older adult's increased risk for motor
vehicle-related injury include visual deterioration and declines in cognitive
and motor skills. Susceptibility to injury in a crash is also increased by
physical frailty. Thus, a crash that results in nonfatal injuries to a younger
person might result in the death of an older adult driver or passenger.
Prevention measures include improving vehicle design, improving visibility of
road signs, installing median islands on wide roadways and screening/testing
programs to help older drivers assess their abilities and to make decisions
[Editor's Note: In the event of a crash, air bags and seat belts will
minimize injuries and prevent fatalities. In addition, the AARP holds 55 ALIVE
driving classes to help motorists over 50 improve driving skills. Discounts on
