Stress Fracture

(Fracture, Stress)

Definition

A stress fracture is a tiny crack in the bone from chronic overuse. Most stress fractures occur in the lower leg and foot. They can also occur in the hip and other areas.

Causes    TOP

A blow to the bone does not cause a stress fracture. Rather, it is typically caused by repeated stress or overuse. Some causes are:

  • Increasing the amount or intensity of an activity too quickly (most common)
  • Switching to a different playing or running surface
  • Wearing improper or old shoes

Stress fractures can worsen by continued physical stress. Smoking can also make stress fractures worse because it interferes with bone healing.

Risk Factors    TOP

Stress fractures are more common in women. Other factors that may increase your chance of a stress fracture include:

  • Sports that involve running and jumping, such as:
    • Tennis
    • Track, especially distance running
    • Gymnastics
    • Dance
    • Basketball
  • Absense or early stopping of menstrual cycle—amenorrhea
  • Reduced bone thickness or density—osteoporosis
  • Poor muscle strength or flexibility
  • Overweight or underweight
  • Poor physical condition

Symptoms    TOP

A stress fracture may cause:

  • Localized pain on the bone
  • Pain when pressure is applied directly over the fracture and the area around it
  • Pain when putting stress on the affected leg
  • Swelling and warmth at injury site

Diagnosis    TOP

The doctor will ask about your symptoms and medical history, and examine the injured area for localized pain and swelling.

Imaging tests to evaluate your bones include:

  • X-rays—stress fractures are very tiny and usually not seen on an x-ray until at least 2 weeks after symptoms begin
  • MRI scan
  • Bone scan

Treatment    TOP

Treatment includes:

Medications

Nonsteroidal anti-inflammatory drugs (NSAIDs) can relieve pain, but controversy exists about their use for stress fractures. It is possible that NSAIDs adversely affect stress fracture healing.

Rest

Rest is the most important thing you can do for a stress fracture. This includes avoiding the activity that caused the fracture and any other activities that cause pain. Rest time required is at least 6-8 weeks.

Crutches or a Cane    TOP

You may need crutches or a walking cane to keep pressure off the leg.

Activity    TOP

Talk with your doctor about when you can restart activity and how to progress with the amount and type of activity.

A common progression:

  • Begin with nonweight–bearing activities, such as swimming or bicycling.
  • Next, you can do weight-bearing, nonimpact exercise, such as a stair machine.
  • Gradually, you will be able to add low-impact activity, starting with walking.
  • Once you can do fast-paced walking with no pain, you can start higher impact activity, such as light jogging.
  • This gradual progression continues until you have reached your pre-injury activity level. You can return to full activity once you do not feel tenderness of the bone.

Prevention    TOP

To help reduce your chance of a stress fracture:

  • Gradually increase the amount and intensity of an activity
  • Run on a softer surface, such as grass, dirt, or certain outdoor tracks
  • Do not overdo any activity
  • Wear proper footwear
  • Maintain a proper weight
  • Avoid smoking
