Metatarsal Stress Fracture
A stress fracture occurs when the bone undergoes more repetitive stress than it can handle. The metatarsal bones in the feet must withstand high loads of force over long periods of time, which makes them a common place for stress fractures to occur.
Symptoms:
- Sharp pain in the ball of the foot during activity.
- Pain or tenderness with pressure to the bone.
- Pain is often felt on the top of the foot.
- Dull to severe ache after activity.
- Mild swelling may occur.
Anatomy:
- The 3rd and 4th metatarsal bones are the most commonly affected.
- May not show up on x-ray until healing begins a few weeks after initial injury.
Treatment and Outcome:
- See your health care provider, if the fracture is severe enough a cast or boot may be warranted.
- X rays may be needed to confirm a fracture.
- Rest: No impact for at least 4-6 weeks. It’s important to give the bone sufficient time to heel.
- Take up a non impact sport to maintain fitness level: (bike or swim)
Causes:
- Too much mileage on hard surfaces.
- Increased speed work or hill training.
- Poor shoes, improper shoe fit, or poor foot mechanics.
- Decreased bone density.
Getting Back into Running:
- Wait until the fracture has healed, running on a stress fracture will make it worse.
- Buy new shoes, the extra cushion can help protect the fracture area from further damage.
- Start out with 25% of the mileage you were previously running.
- Stick to soft surfaces: grass, dirt or treadmill.
Always consult your physician before starting any new exercise program.
