Achilles tendon rupture
DEFINITION
Achilles (uh-KILL-eez) tendon rupture is an injury that affects the back of your lower leg. It most commonly occurs in people playing recreational sports.
The Achilles tendon is a strong fibrous cord that connects the muscles in the back of your calf to your heel bone. If you overstretch your Achilles tendon, it can tear (rupture) completely or just partially.
If your Achilles tendon ruptures, you might feel a pop or snap, followed by an immediate sharp pain in the back of your ankle and lower leg that is likely to affect your ability to walk properly. Surgery is often the best option to repair an Achilles tendon rupture. For many people, however, nonsurgical treatment works just as well.
CAUSES
Your Achilles tendon helps you point your foot downward, rise on your toes and push off your foot as you walk. You rely on it virtually every time you move your foot.
Rupture usually occurs in the section of the tendon located within 2 1/2 inches (about 6 centimeters) of the point where it attaches to the heel bone. This section may be predisposed to rupture because it gets less blood flow, which also may impair its ability to heal.
Ruptures often are caused by a sudden increase in the amount of stress on your Achilles tendon. Common examples include:
- Increasing the intensity of sports participation, especially in sports that involve jumping
- Falling from a height
- Stepping into a hole
SYMPTOMS
Although it’s possible to have no signs or symptoms with an Achilles tendon rupture, most people experience:
- Pain, possibly severe, and swelling near your heel
- An inability to bend your foot downward or “push off” the injured leg when you walk
- An inability to stand on your toes on the injured leg
- A popping or snapping sound when the injury occurs
When to see your doctor
Seek medical advice immediately if you feel a pop or snap in your heel, especially if you can’t walk properly afterward.
