Stress Fractures
Stress Fractures - One of the
most common injuries in sports is a stress fracture.
Overcoming an injury like a stress fracture can
be difficult, but it can be done.
What is a stress fracture? A stress fracture is an overuse
injury. It occurs when muscles become fatigued and are unable to absorb added
shock. Eventually, the fatigued muscle transfers the overload of stress to the
bone causing a tiny crack called a stress fracture.
What causes a stress fracture? Stress fractures often are
the result of increasing the amount or intensity
of running too rapidly. They also can be caused
by the impact of an unfamiliar surface (a runner
who has switched surfaces from a dirt trail to a
hard concrete sidewalk); improper equipment (a runner
using worn or less flexible shoes); and increased
physical stress (a substantial increase in the intensity
and volume of training over several weeks to several
months).
Are women more susceptible to stress fractures than men? Medical
studies have shown that female athletes seem to
experience more stress fractures than their male
counterparts. Many orthopedic surgeons attribute
this fact to a condition referred to as "the
female athlete triad"-eating disorders (bulimia
or anorexia), amenorrhea (infrequent menstrual cycle),
and osteoporosis. As a female's bone mass decreases,
the chances of getting a stress fracture increase.
Where do stress fractures occur? Most stress fractures occur
in the weight bearing bones of the lower leg and the foot. More than 50 percent
of all stress fractures occur in the lower leg.
What activities make runners most susceptible to stress fractures?
Studies have shown that athletes participating in track and field are
very susceptible to stress fractures. The repetitive stress of the foot striking
the ground can cause trauma. Without sufficient rest between workouts or competitions,
a runner risks developing a stress fracture.
How are stress fractures treated? The most important treatment
is rest. Runners need to rest from running and engage in a pain-free activity
during the six to eight weeks it takes most stress fractures to heal. If running
is resumed too quickly, larger, harder-to-heal stress fractures can develop.
Reinjury also could lead to chronic problems where the stress fracture might
never heal properly.
Here are some tips help prevent stress fractures:
- Slowly increase your mileage. For example, do not immediately start running
five miles a day; instead gradually build up your mileage on a weekly basis.
Running also can be done on alternate days. Try alternating the days you run
on a weekly basis.
- Maintain a healthy diet. Make sure you incorporate calcium-rich foods in
your meals.
- Use the proper equipment. Do not wear old or worn running shoes.
- If pain or swelling occurs, immediately stop the activity and rest for a
few days. If continued pain persists, see an orthopedic
surgeon.
It is important to remember that if you recognize the symptoms early and treat
them appropriately, you can return to running at your normal level.
