Achilles Tendon

Achilles Tendonitis Pain And discomfort Cause

Overview

Achilles TendonAchilles 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.

Causes

There are two large muscles in the calf. These muscles are important for walking. They create the power needed to push off with the foot or go up on the toes. The large Achilles tendon connects these muscles to the heel. Heel pain is most often due to overuse of the foot. Rarely it is caused by an injury. Tendinitis due to overuse is most common in younger people. It can occur in walkers, runners, or other athletes. Achilles tendinitis may be more likely to occur if you Suddenly increase the amount or intensity of an activity. Your calf muscles are very tight (not stretched out). You run on hard surfaces such as concrete. You run too often, you jump a lot (such as when playing basketball), you do not have shoes with proper support, your foot suddenly turns in or out. Tendinitis from arthritis is more common in middle-aged and elderly people. A bone spur or growth may form in the back of the heel bone. This may irritate the Achilles tendon and cause pain and swelling.

Symptoms

There are several types of Achilles tendinitis symptoms, but all of them are closely related. People who suffer from Achilles tendon pain typically have swelling in the Achilles tendon, and that pain can be chronic as the microscopic tears in the area become more prevalent over time. The most intense pain is typically located just a few centimeters above the area where the tendon meets the heel. This area is called the watershed zone, and the amount of blood moving through it is what gives it the highest potential for injury, especially for athletes. Most of the Achilles tendinitis symptoms in people with the condition will happen immediately after they have been inactive for a fairly significant amount of time. That means that the most pain will generally be felt after sitting or lying down for an extended period, or right after waking up in the morning and getting moving. If you aren?t positive that you are suffering specifically from Achilles tendinitis symptoms, consult a doctor to make sure.

Diagnosis

Examination of the achilles tendon is inspection for muscle atrophy, swelling, asymmetry, joint effusions and erythema. Atrophy is an important clue to the duration of the tendinopathy and it is often present with chronic conditions. Swelling, asymmetry and erythema in pathologic tendons are often observed in the examination. Joint effusions are uncommon with tendinopathy and suggest the possibility of intra-articular pathology. Range of motion testing, strength and flexibility are often limited on the side of the tendinopathy. Palpation tends to elicit well-localized tenderness that is similar in quality and location to the pain experienced during activity. Physical examinations of the Achilles tendon often reveals palpable nodules and thickening. Anatomic deformities, such as forefoot and heel varus and excessive pes planus or foot pronation, should receive special attention. These anatomic deformities are often associated with this problem. In case extra research is wanted, an echography is the first choice of examination when there is a suspicion of tendinosis. Imaging studies are not necessary to diagnose achilles tendonitis, but may be useful with differential diagnosis. Ultrasound is the imaging modality of first choice as it provides a clear indication of tendon width, changes of water content within the tendon and collagen integrity, as well as bursal swelling. MRI may be indicated if diagnosis is unclear or symptoms are atypical. MRI may show increased signal within the Achilles.

Nonsurgical Treatment

Most cases are successfully treated non-surgically although this is time-consuming and frustrating for active patients. Treatment is less likely to be successful if symptoms have been present more than six months. Nonsurgical management includes nonsteroidal anti-inflammatory medications, rest, immobilization, limitation of activity, ice, contrast baths, stretching and heel lifts. If symptoms fail to resolve after two to three months, a formal physical therapy program may be of benefit. An arch support may help if there is an associated flatfoot. A cast or brace to completely rest this area may be necessary. Extracorporeal shockwave therapy and platelet-rich plasma injections? have variable reports of success. Nitroglycerin medication applied to the overlying skin may be of benefit.

Achilles Tendinitis

Surgical Treatment

Surgery should be considered to relieve Achilles tendinitis only if the pain does not improve after 6 months of nonsurgical treatment. The specific type of surgery depends on the location of the tendinitis and the amount of damage to the tendon. Gastrocnemius recession. This is a surgical lengthening of the calf (gastrocnemius) muscles. Because tight calf muscles place increased stress on the Achilles tendon, this procedure is useful for patients who still have difficulty flexing their feet, despite consistent stretching. In gastrocnemius recession, one of the two muscles that make up the calf is lengthened to increase the motion of the ankle. The procedure can be performed with a traditional, open incision or with a smaller incision and an endoscope-an instrument that contains a small camera. Your doctor will discuss the procedure that best meets your needs. Complication rates for gastrocnemius recession are low, but can include nerve damage. Gastrocnemius recession can be performed with or without d?bridement, which is removal of damaged tissue. D?bridement and repair (tendon has less than 50% damage). The goal of this operation is to remove the damaged part of the Achilles tendon. Once the unhealthy portion of the tendon has been removed, the remaining tendon is repaired with sutures, or stitches to complete the repair. In insertional tendinitis, the bone spur is also removed. Repair of the tendon in these instances may require the use of metal or plastic anchors to help hold the Achilles tendon to the heel bone, where it attaches. After d?bridement and repair, most patients are allowed to walk in a removable boot or cast within 2 weeks, although this period depends upon the amount of damage to the tendon. D?bridement with tendon transfer (tendon has greater than 50% damage). In cases where more than 50% of the Achilles tendon is not healthy and requires removal, the remaining portion of the tendon is not strong enough to function alone. To prevent the remaining tendon from rupturing with activity, an Achilles tendon transfer is performed. The tendon that helps the big toe point down is moved to the heel bone to add strength to the damaged tendon. Although this sounds severe, the big toe will still be able to move, and most patients will not notice a change in the way they walk or run. Depending on the extent of damage to the tendon, some patients may not be able to return to competitive sports or running. Recovery. Most patients have good results from surgery. The main factor in surgical recovery is the amount of damage to the tendon. The greater the amount of tendon involved, the longer the recovery period, and the less likely a patient will be able to return to sports activity. Physical therapy is an important part of recovery. Many patients require 12 months of rehabilitation before they are pain-free.

Prevention

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.
