Achilles Tendon Rupture

GENERAL INFORMATION:

What is an Achilles tendon rupture?

• Your Achilles tendon has ruptured if it gets a tear in it. A tendon is body tissue that connects your muscles to your bones. Your Achilles tendon connects your calf muscle in your lower leg to your heel bone. It is the strongest tendon in your body. Your Achilles tendon acts like a spring by taking the force (pressure) from your body when it moves. Your Achilles tendon also allows you to point your foot downward and rise on your toes. This allows you to push your foot toward the ground, such as when walking, running, or jumping.
  
  
• A rupture can be a partial (incomplete) or complete tear. It can be acute (sudden) or chronic if you do not get treatment right away. A rupture often occurs just above your heel bone in one or both of your legs. You may also get a rupture anywhere along your Achilles tendon. Having your Achilles tendon treated may help increase the strength in your leg muscles. It may also help you to walk normally again. Treatment may help decrease your pain. You may be able to return to work sooner and more easily complete your normal daily activities.

What causes an Achilles tendon rupture? Your Achilles tendon will rupture if there is too much pressure put on it. This can happen when playing sports. It can also happen during falls, like down stairs and ladders. Your Achilles tendon may rupture when it is directly injured, such as when hit or kicked. Why your Achilles tendon ruptures is not exactly known. It may be caused by decreased blood flow to your tendon or changes to your tissue or bone.

What may increase my risk of having an Achilles tendon rupture?

• Your body: You may have an abnormal bone structure in your foot. Your Achilles tendon may have been ruptured before. Your tendon may have inflammation (swelling). These conditions make your Achilles tendon weaker and more likely to tear. Being overweight (weighing more than your caregiver suggests) may put too much stress on your Achilles tendon.
  
  
• Activity: If you are not usually physically active, then your Achilles tendon may be weak. If you become active but have a weak Achilles tendon, then it may rupture. This often happens when people start playing sports after not being physically active for a long time.
  
  
• Age: As you get older, your Achilles tendon may become stiffer and less flexible. This may make your tendon more likely to tear.
  
  
• Medical conditions: You may have medical conditions that affect your tendons. Rheumatoid arthritis is a disease of your joints that causes inflammation and new bone growth. Your joints are where two bones meet, like your ankle. Other medical conditions include diabetes (high blood sugar) and kidney problems. Your kidneys are bean-shaped organs that turn chemicals and waste from your blood into urine. Other medical conditions may also make your tendons weaker and more likely to tear. Ask your caregiver for more information about these conditions.
  
  
• Medicines: Certain medicines may make your Achilles tendon weak and more likely to rupture. You may have taken anabolic steroids to help your muscles grow. You may have also taken corticosteroid medicine to decrease swelling. Fluoroquinolone medicine is a kind of antibiotics, which are used to fight infections caused by bacteria (germs). You may have taken these medicines either by mouth or as shots into your skin.

What are the signs and symptoms of an Achilles tendon rupture? You may have any of the following:

• A sudden pop, snap, or crack at the back of your leg or heel.
  
  
• Severe pain in your leg or the back of your ankle.
  
  
• Swelling, stiffness, or weakness in your leg or foot.
  
  
• A bruise on the back of your leg or foot.
  
  
• Falling forward while you walk.
  
  
• Trouble balancing or putting weight on your leg.
  
  
• Trouble going up and down stairs.
  
  
• Trouble moving your leg or foot.

How is an Achilles tendon rupture diagnosed? Your caregiver will ask you about your symptoms and your recent physical activities. He will also ask what you were doing at the time of your injury. Tell your caregiver about your past medical conditions and what medicines you take. Your caregiver will look at your ankle area and the back of your leg very closely. He may look or feel for a gap on the back of your leg near your ankle. He may also do any of the following:

• Calf-squeeze test: Your caregiver will ask you to lie on your stomach on a table or bed. Your feet will hang over the edge. Your caregiver will squeeze the lower part of your calves. Your caregiver may then repeat the test on your other leg to compare them to each other. If your foot does not move when your calf is squeezed, you may have a torn Achilles tendon.
  
  
• Heel raise test: This is also called a tiptoe test. You may be asked to stand on your toes so your heels are raised off the ground. If this is hard for you to do then you may have an Achilles tendon tear.
  
  
• Knee flexion test: Your caregiver will ask you to lie on your stomach on a table or bed. You will be asked to bend your knees until your lower leg is straight up. If your injured foot points downward then your Achilles tendon may have a tear.
  
  
• Needle test: Your caregiver will insert a needle a few inches above your heel into the skin of your calf. Your caregiver will then move your foot in a downward and then upward direction. While doing this, your caregiver will see if the needle moves while your foot is pointing upward. You may have an Achilles tendon rupture if the needle does not move or points downwards.
  
  
• Sphygmomanometer test: A sphygmomanometer is the cuff put around your arm when your caregiver takes your blood pressure. During this test, you will be asked to lie on your stomach on the examining table or bed. The cuff will be wrapped around the middle of your calf. The cuff is filled with air and then your caregiver moves your foot towards your body. If the pressure in your calf does not increase, then you may have an Achilles tendon rupture.

What imaging tests might I need for an Achilles tendon rupture? Your caregiver may use imaging tests to help confirm whether your have torn your Achilles tendon. He may also use these tests to help him check for other problems that may be causing your symptoms.

• X-rays: Your caregiver may take x-rays of your ankle and foot. This may help your caregiver see if there is swelling in your tendons or muscles. He may also see if you have broken any bones. An x-ray may also show changes in the shape of the tendon and surrounding spaces.
  
  
• Magnetic resonance imaging: This is also called an MRI. Your caregiver will use this test to see how much tendon damage you have. This test may also show if you have swelling and bleeding around the torn tendon. During the MRI, pictures are taken of your Achilles tendon and the muscles and bones around it. You will need to lie still during a MRI. Never enter the MRI room with an oxygen tank, watch, or any other metal objects. This can cause serious injury.
  
  
• Ultrasound: An ultrasound is a simple test that looks at the inside of your body. Sound waves are used to show pictures of your Achilles tendon on a TV-like screen. This may help your caregiver see if your Achilles tendon is torn.

How is an Achilles tendon rupture treated? There are both surgery and non-surgery treatments for your Achilles tendon rupture. Your treatment will depend on your health, age, level of activity, and type of rupture. You and your caregiver will decide on the treatment that is best for you.

• Non-surgery choices:
  
  
  • Casts: Your caregiver may put a cast on your leg. This cast may stay on your leg for two months or more. This cast may go up to your knee or may extend past your knee. Your foot will be put into a position with your toes pointing slightly downwards. Your caregiver will change your cast and your foot position several times during the time you are healing. You will not be able to move your foot and ankle until your Achilles tendon heals. Do not move or put weight on your foot until your caregiver tells you it is OK.
    
    
  • Leg braces: You may be asked to wear a leg brace or splint to prevent you from moving your foot. These braces allow you to move your leg and walk, but not until your caregiver says it is OK. Leg braces may also help you from getting another injury in your leg, ankle, or foot.
    
    
  • Heel lifts: Heel lifts are special wedges that are inserted into your shoes or cast. Heel lifts help keep your foot in the best position for healing.
  
  
• Surgery choices:
  
  
  • Open surgery: Your caregiver will make a cut on the back of your leg next to your ruptured Achilles tendon. The edges of your Achilles tendon will be sewn back together with special thread (sutures). If your tear is very wide, your caregiver may use pieces of another tendon or man-made material. These are called grafts and are used to patch up the tear in your Achilles tendon. Your caregiver will then close the cut with stitches and put your leg in a cast.
    
    
  • Percutaneous surgery: Your caregiver will make several small cuts on the skin near your ruptured Achilles tendon. Your caregiver will then use special tools to sew up your Achilles tendon. Your caregiver will then close the small cuts with stitches and put your leg in a cast.

What are the risks of having my Achilles tendon rupture treated? If you are treated with a cast or brace then your Achilles tendon may rupture again. You may get an infection or a tear in your skin. You may also get an infection if you have surgery. You may develop keloids (big scars), skin problems, or numbness where you had your surgery. A blood clot may form in the veins of your leg and may cause a pulmonary embolism (PE). A PE is when a blood clot blocks an artery (blood vessel) in your lungs. A blood clot may also cause a heart attack or a stroke. You may die from these conditions.

• You have swelling or pain in your ankle or heel area.
  
  
• One of your legs is swollen larger than the other.
  
  
• The muscles in your legs become weak.
  
  
• You have a fever (high body temperature).
