Broken foot bone; March fracture; March foot; Jones fracture
The metatarsal bones are the long bones in your foot that connect your ankle to your toes. A stress fracture is a break in the bone that happens with repeated injury or stress. Stress fractures are caused by overly stressing the foot when using it in the same way repeatedly.
A stress fracture is different from an acute fracture, which is caused by a sudden and traumatic injury.
About Your Injury
Stress fractures are common in people who:
Increase their activity level suddenly
Do activities that put a lot of pressure on their feet, such as running, dancing, jumping, or marching (as in the military)
Have a bone condition such as osteoporosis (thin, weak bones) or arthritis (inflamed joints)
Have a nervous system disorder that causes loss of feeling in the feet
Pain is an early sign of a metatarsal stress fracture. The pain may occur:
During activity, but go away with rest
Over a wide area of your foot
Over time, the pain will be:
Present all the time
Stronger in one area of your foot
The area of your foot where the fracture is may be tender when you touch it. It may also be swollen.
What to Expect
An x-ray may not show there is a stress fracture for up to 6 weeks after the fracture occurs. Your doctor may order a bone scan or MRI to help diagnose it.
You may wear a special shoe to support your foot. If your pain is severe, you may have a cast below your knee.
It may take 4 to 12 weeks for your foot to heal.
Self-care at Home
It is important to rest your foot.
Elevate your foot to decrease swelling and pain.
Do not do the activity or exercise that caused your fracture.
If walking is painful, your doctor may advise you to use crutches to help support your body weight when you walk.
To Treat Pain
For pain, you can take over-the-counter nonsteroidal anti-inflammatory drugs (NSAIDs).
Examples of NSAIDs are ibuprofen (such as Advil or Motrin) and naproxen (such as Aleve or Naprosyn).
Do not give aspirin to children.
If you have heart disease, high blood pressure, kidney disease, or have had stomach ulcers or bleeding, talk with your doctor before using these medicines.
Do not take more than the amount recommended on the bottle.
As you recover, your doctor will examine how well your foot is healing. The doctor will tell you when you can stop using crutches or have your cast removed. Also check with your doctor about when you can start certain activities again.
You can return to normal activity when you can perform the activity without pain.
When you restart an activity after a stress fracture, build up slowly. If your foot begins to hurt, stop and rest.
When to Call the Doctor
Call your doctor if you have pain that does not go away or gets worse.
