Achilles tendinitis is a common condition that causes pain along the back of the leg near the heel. The Achilles tendon is the largest tendon in the body. It connects your calf muscles to your heel bone and is used when you walk, run, and jump. Although the Achilles tendon can withstand great stresses from running and jumping, it is also prone to tendinitis, a condition associated with overuse and degeneration. Simply defined, tendinitis is inflammation of a tendon. Inflammation is the body’s natural response to injury or disease, and often causes swelling, pain, or irritation. There are two types of Achilles tendinitis, based upon which part of the tendon is inflamed. Noninsertional Achilles tendinitis, Noninsertional Achilles Tendinitis. In noninsertional In both noninsertional and insertional Achilles tendinitis, damaged tendon fibers may also calcify (harden). Tendinitis that affects the insertion of the tendon can occur at any time, even in patients who are not active.
Achilles tendinitis may be caused by intensive hill running, sprinting, or stair climbing. Overuse resulting from the natural lack of flexibility in the calf muscles. Rapidly increasing intensity of exercise, especially after a period of inactivity. Sudden and hard contraction of the calf muscles when exerting extra effort, like that in a final sprint or high jump.
Symptoms include pain in the heel and along the tendon when walking or running. The area may feel painful and stiff in the morning. The tendon may be painful to touch or move. The area may be swollen and warm. You may have trouble standing up on one toe.
Physicians usually pinch your Achilles tendon with their fingers to test for swelling and pain. If the tendon itself is inflamed, your physician may be able to feel warmth and swelling around the tissue, or, in chronic cases, lumps of scar tissue. You will probably be asked to walk around the exam room so your physician can examine your stride. To check for complete rupture of the tendon, your physician may perform the Thompson test. Your physician squeezes your calf; if your Achilles is not torn, the foot will point downward. If your Achilles is torn, the foot will remain in the same position. Should your physician require a closer look, these imaging tests may be performed. X-rays taken from different angles may be used to rule out other problems, such as ankle fractures. MRI (magnetic resonance imaging) uses magnetic waves to create pictures of your ankle that let physicians more clearly look at the tendons surrounding your ankle joint.
Treatment options might include anti-inflammatory medication such as ibuprofen which might help with acute achilles inflammation and pain but has not been proven to be beneficial long term and may even inhibit healing. If the injury is severe then a plaster cast might be applied to immobilize the tendon. Use of electrotherapy such as ultrasound treatment, laser therapy and extracorporeal shock wave therapy (ESWT) may be beneficial in reducing pain and encouraging healing. Applying sports massage techniques can mobilze the tissues or the tendon itself and help stretch the calf muscles. Some might give a steroid injection however an injection directly into the tendon is not recommended. Some specialists believe this can increase the risk of a total rupture of the tendon in future. One of the most effective forms of treatment for achilles tendonitis is a full rehabilitation program consisting of eccentric strengthening exercises. There is now considerable evidence suggesting the effectiveness of slow eccentric rehabilitation exercises for curing achilles tendon pain.
In cases of severe, long-term Achilles tendonitis the sheath may become thick and fibrous. In these cases surgery may be recommended. Surgery aims to remove the fibrous tissue and repair any tears in the tendon. A cast or splint will be required after the operation and a recovery program including physiotherapy, specific exercises and a gradual return to activity will be planned.
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.
