Achilles Tendonitis Causes
Overview
Achilles tendinitis (or Achilles tendonitis) is a strain of the Achilles tendon, which connects the calf muscles to the heel bone. Pain can be moderate or severe, but the condition is not usually serious. Of course, if you are suffering the leg and heel pain it brings, it certainly feels serious enough.
Causes
Achilles tendonitis is a common sports injury caused by repeated or intense strain on the tendon. But non-athletes also can get it if they put a lot of stress on their feet. Other things that contribute to Achilles tendonitis include. An increase in activity. Starting a training program after a period of inactivity or adding miles or hills to a jogging regimen are two examples of things that put people at risk for Achilles tendonitis. Sports that require sudden starts and stops; for example, tennis and basketball. A change in footwear, or wearing old or badly fitting shoes. New shoes, worn-out shoes, or the wrong size shoes can cause a person's feet to overcompensate and put stress on the Achilles tendon. Additionally, wearing high heels all the time can cause the tendon and calf muscles to get shorter, and the switch to flat shoes and exercise can put extra strain on the heel. Running up hills. Going uphill forces the Achilles tendon to stretch beyond its normal range. Weak calf muscles, flat arches, "overpronation" (feet that roll in when running), or "oversupination" (feet that roll out when running). Overpronation and oversupination make the lower leg rotate and put a twisting stress on the tendon. Exercising without warming up. Tight calf muscles or muscles that lack flexibility decrease a person's range of motion and put an extra strain on the tendon. Running or exercising on a hard or uneven surface or doing lunges or plyometrics without adequate training. A traumatic injury to the Achilles tendon.
Symptoms
Symptoms vary because you can injure various areas of the muscle-tendon complex. The pain may be an acute or chronic sharp, stabbing, piercing, shooting, burning or aching. It is often most noticeable immediately after getting out of bed in the morning, or after periods of inactivity, like sitting down for lunch. After a couple minutes of walking around, it will often then settle down somewhat, before becoming symptomatic again after excessive time standing or walking. But regardless of how the pain is perceived, Achilles tendon pain should not be left untreated due to the danger that the tendon can become weak, frayed, thickened, and eventually it may rupture.
Diagnosis
A podiatrist can usually make the diagnosis by clinical history and physical examination alone. Pain with touching or stretching the tendon is typical. There may also be a visible swelling to the tendon. The patient frequently has difficulty plantarflexing (pushing down the ball of the foot and toes, like one would press on a gas pedal), particularly against resistance. In most cases X-rays don't show much, as they tend to show bone more than soft tissues. But X-rays may show associated degeneration of the heel bone that is common with Achilles Tendon problems. For example, heel spurs, calcification within the tendon, avulsion fractures, periostitis (a bruising of the outer covering of the bone) may all be seen on X-ray. In cases where we are uncertain as to the extent of the damage to the tendon, though, an MRI scan may be necessary, which images the soft tissues better than X-rays. When the tendon is simply inflamed and not severely damaged, the problem may or may not be visible on MRI. It depends upon the severity of the condition.
Nonsurgical Treatment
Relieving the stress is the first course of action. Treatment involves ice therapy and activity modification to reduce inflamation. Active stretching and strengthening exercises will assist rehabilitation of the gastrocnemius-soleus complex. When placed in a heeled shoe, the patient will immediately notice a difference, compared to flat ground. It is recommended that the patient be fitted with proper shoes & orthotics to control pronation and maintain proper alignment, relieving the stress on the achilles tendon. Tightness in the tendon itself can be helped by an extra heel lift added to the orthotics. The patient can expect a slow recovery over a period of months.
Surgical Treatment
Percutaneous Achilles Tendon Surgery. During this procedure the surgeon will make 3 to 4 incisions (approx. 2.5 cm long) on both sides of the Achilles tendon. Small forceps are used to free the tendon sheath (the soft tissue casing around your Achilles tendon) to make room for the surgeon to stitch/suture any tears. Skilled surgeons may perform a percutaneous achilles tendon surgery with ultrasound imaging techniques to allow for blink suturing with stab incisions made by a surgical suture needle. This procedure can be done in 3 different ways depending on the preference and experience of your surgeon. Instead of making several 2.5 cm incisions for this procedure, some surgeons will use guided imaging with an ultrasound to see the Achilles tendon tissue without having to open up your ankle. For this technique, they will use a surgical needle to repeatedly stab your Achilles tendon. These "stab incisions" will allow the surgeon to "blindly" suture your tendon without seeing the actual tissue. As another option - some surgeons will only make 1 to 3 incisions for smaller surgical implements to repair your tendon while relying on imaging ultrasound to see your damaged tissue. During either procedure the use of ultrasound imaging or endoscopic techniques requires a very skilled surgeon.
Prevention
While it may not be possible to prevent Achilles tendinitis, you can take measures to reduce your risk. Increase your activity level gradually. If you're just beginning an exercise regimen, start slowly and gradually increase the duration and intensity of the training. Take it easy. Avoid activities that place excessive stress on your tendons, such as hill running. If you participate in a strenuous activity, warm up first by exercising at a slower pace. If you notice pain during a particular exercise, stop and rest. Choose your shoes carefully. The shoes you wear while exercising should provide adequate cushioning for your heel and should have a firm arch support to help reduce the tension in the Achilles tendon. Replace your worn-out shoes. If your shoes are in good condition but don't support your feet, try arch supports in both shoes. Stretch daily. Take the time to stretch your calf muscles and Achilles tendon in the morning, before exercise and after exercise to maintain flexibility. This is especially important to avoid a recurrence of Achilles tendinitis. Strengthen your calf muscles. Strong calf muscles enable the calf and Achilles tendon to better handle the stresses they encounter with activity and exercise. Cross-train. Alternate high-impact activities, such as running and jumping, with low-impact activities, such as cycling and swimming.
