Tendinitis is a painful condition. Running and walking are made possible by the Achilles tendon, which attaches the calf muscle to the heel bone. Strenuous exercise, jumping, and climbing are all
movements that can strain the tendon and calf muscles, causing an inflammation known as tendinitis. The injury to the Achilles can be mild, requiring only rest and over-the-counter anti-inflammatory
drugs, or severe, necessitating surgical repair of the damaged tendon. Chronic Achilles tendinitis can lead to micro tears in the tissue (tendinosis), which weaken the tendon and put it at risk for
severe damage such as a tear or rupture.
There are a number of ways a person can develop Achilles tendinitis. Some causes are easier to avoid than others, but being aware of them can aid earlier diagnosis and help prevent serious injury.
Causes of Achilles tendinitis include, using incorrect or worn out shoes when running or exercising. Not warming up properly before exercise. Increasing intensity of exercise too quickly (e.g.
running speed or distance covered). Prematurely introducing hill running or stair climbing to exercise routine. Running on hard or uneven surfaces. Calf muscle is injured or has little flexibility
(this puts a lot of strain on the Achilles tendon). Sudden intense physical activity such as sprinting for the finish line. Achilles tendinitis can also be caused by differences in foot, leg or ankle
anatomy. For example, some people can have flatness in their foot where there would normally be an arch; this puts more strain on the tendon. The FDA has asked that a boxed warning be added to the
prescribing information for fluoroquinolone antibiotics. Patients taking these drugs may experience an increased risk of tendinitis and tendon rupture. Fluoroquinolones include Cipro (ciprofloxacin),
Factive (gemifloxacin), Levaquin (levofloxacin), Avelox (moxifloxacin), Noroxin (norfloxacin), Floxin (ofloxacin) and Proquin (ciprofloxacin hydrochloride). It is important to remember that the risk
for injury is not necessarily gone when the drug is stopped. Cases have been reported in which tendon problems occurred up to several months after the drug was discontinued.
Pain in the back of the heel that can be a shooting pain, burning pain or even an intense piercing pain. Swelling, tenderness and warmth over the Achilles tendon especially at the insertion of the
tendon to the calcaneous, which may even extend into the muscle of the calf. Difficulty walking, sometimes the pain makes walking impossible. Pain that is aggravated by activities that repeatedly
stress the tendon, causing inflammation or pain that occurs in the first few steps of the morning or after sitting down for extended periods of time which gets better with mild activity. It is
important to note though that achilles tendinosis can develop gradually without a history of trauma.
During an examination of the foot and ankle, you doctor will look for the following signs, Achilles tendon swelling or thickening. Bone spurs appearing at the lower part of the tendon at the back of
the hell. Pain at the middle or lower area of the Achilles tendon. Limited range of motion of the foot and ankle, and a decreased ability to flex the foot. Your doctor may perform imaging tests, such
as X-rays and MRI scans, to make a diagnosis of Achilles tendinitis. X-rays show images of the bones and can help the physician to determine if the Achilles tendon has become hardened, which
indicated insertional Achilles tendinitis. MRI scans may not be necessary, but they are important guides if you are recommended to have surgical treatment. An MRI can show the severity of the damage
and determine what kind of procedure would be best to address the condition.
In most cases, nonsurgical treatment options will provide pain relief, although it may take a few months for symptoms to completely subside. Even with early treatment, the pain may last longer than 3
months. If you have had pain for several months before seeking treatment, it may take 6 months before treatment methods take effect. The first step in reducing pain is to decrease or even stop the
activities that make the pain worse. If you regularly do high-impact exercises (such as running), switching to low-impact activities will put less stress on the Achilles tendon. Cross-training
activities such as biking, elliptical exercise, and swimming are low-impact options to help you stay active. Placing ice on the most painful area of the Achilles tendon is helpful and can be done as
needed throughout the day. This can be done for up to 20 minutes and should be stopped earlier if the skin becomes numb. A foam cup filled with water and then frozen creates a simple, reusable ice
pack. After the water has frozen in the cup, tear off the rim of the cup. Then rub the ice on the Achilles tendon. With repeated use, a groove that fits the Achilles tendon will appear, creating a
"custom-fit" ice pack. Drugs such as ibuprofen and naproxen reduce pain and swelling. They do not, however, reduce the thickening of the degenerated tendon. Using the medication for more than 1 month
should be reviewed with your primary care doctor. The following exercise can help to strengthen the calf muscles and reduce stress on the Achilles tendon. Lean forward against a wall with one knee
straight and the heel on the ground. Place the other leg in front, with the knee bent. To stretch the calf muscles and the heel cord, push your hips toward the wall in a controlled fashion. Hold the
position for 10 seconds and relax. Repeat this exercise 20 times for each foot. A strong pull in the calf should be felt during the stretch. Physical therapy is very helpful in treating Achilles
tendinitis. It has proven to work better for noninsertional tendinitis than for insertional tendinitis. Eccentric strengthening is defined as contracting (tightening) a muscle while it is getting
longer. Eccentric strengthening exercises can cause damage to the Achilles tendon if they are not done correctly. At first, they should be performed under the supervision of a physical therapist.
Once mastered with a therapist, the exercises can then be done at home. These exercises may cause some discomfort, however, it should not be unbearable. Stand at the edge of a stair, or a raised
platform that is stable, with just the front half of your foot on the stair. This position will allow your heel to move up and down without hitting the stair. Care must be taken to ensure that you
are balanced correctly to prevent falling and injury. Be sure to hold onto a railing to help you balance. Lift your heels off the ground then slowly lower your heels to the lowest point possible.
Repeat this step 20 times. This exercise should be done in a slow, controlled fashion. Rapid movement can create the risk of damage to the tendon. As the pain improves, you can increase the
difficulty level of the exercise by holding a small weight in each hand. This exercise is performed similarly to the bilateral heel drop, except that all your weight is focused on one leg. This
should be done only after the bilateral heel drop has been mastered. Cortisone, a type of steroid, is a powerful anti-inflammatory medication. Cortisone injections into the Achilles tendon are rarely
recommended because they can cause the tendon to rupture (tear).
Following the MRI or ultrasound scan of the Achilles tendon the extent of the degenerative change would have been defined. The two main types of operation for Achilles tendinosis are either a
stripping of the outer sheath (paratenon) and longitudinal incisions into the tendon (known as a debridement) or a major excision of large portions of the tendon, the defects thus created then being
reconstructed using either allograft (donor tendon, such as Wright medical graft jacket) or more commonly using a flexor hallucis longus tendon transfer. In cases of Achilles tendonosis with more
minor degrees of degenerative change the areas can be stimulated to repair itself by incising the tendon, in the line of the fibres, which stimulates an ingrowth of blood vessels and results in the
healing response. With severe Achilles tendonosis, occasionally a large area of painful tendon needs to be excised which then produces a defect which requires filling. This is best done by
transferring the flexor hallucis longus muscle belly and tendon, which lies adjacent to the Achilles tendon. This results in a composite/double tendon after the operation, with little deficit from
the transferred tendon.
Suggestions to reduce your risk of Achilles tendonitis include, icorporate stretching into your warm-up and cool-down routines. Maintaining an adequate level of fitness for your sport. Avoid dramatic
increases in sports training. If you experience pain in your Achilles tendon, rest the area. Trying to ?work through? the pain will only make your injury worse. Wear good quality supportive shoes
appropriate to your sport. If there is foot deformity or flattening, obtain orthoses. Avoid wearing high heels on a regular basis. Maintaining your foot in a ?tiptoe? position shortens your calf
muscles and reduces the flexibility of your Achilles tendon. An inflexible Achilles tendon is more susceptible to injury. Maintain a normal healthy weight.
