Bursas are small fluid containing sacs, that are situated between areas of high friction such as bone against the floor (heel) and bone against other soft tissue structures like tendons, skin and or muscle. The bursa job is to act as a shock absorber, and to allow stress free movement between the above noted structures. Bursitis is a swellinginflammation of the bursa sac, due to constant micro trauma or overuse. In the foot Abnormal Pronation, most often caused by Morton?s Toe.
Inflammation of the calcaneal bursae is most commonly caused by repetitive overuse and cumulative trauma, as seen in runners wearing tight-fitting shoes. Such bursitis may also be associated with conditions such as gout, rheumatoid arthritis, and seronegative spondyloarthropathies. In some cases, subtendinous calcaneal bursitis is caused by bursal impingement between the Achilles tendon and an excessively prominent posterior superior aspect of a calcaneus that has been affected by Haglund deformity. With Haglund disease, impingement occurs during ankle dorsiflexion.
Pain at the back of the heel, especially with jumping, hopping, tip-toeing, walking or running uphill or on soft surfaces. If tendonitis is also present, the pain can radiate away from the bursa. Direct pressure on the bursa will exacerbate the pain and should be avoided if possible. Tenderness and swelling which might make it difficult to wear certain shoes on the feet. As the bursa becomes more inflamed you will experience swelling and warmth. In severe cases, the bursa will appear as a bump, called a "pump bump", and is usually red, and extremely tender. Swelling can cause difficulties moving as the range of motion in the ankle can be affected. Limping due to the pain may occur. If you press on both sides of the inflamed heel, there may be a firm spongy feeling. Weakness in the tendons and muscles surrounding the bursa can develop as the pain worsens and the inflammation in the area spreads. Possibly a fever if you are suffering from septic bursitis (You will need to see a doctor for medication to get rid of the infection). Pain at the back of the heel makes it difficult to continue wearing shoes, especially high heels with straps or shoes that don't fit properly.
Your doctor will take a history to find out if you have the symptoms of retrocalcaneal bursitis. By examining your ankle, he or she can generally tell the location of the pain. The physician will look for tenderness and redness in the back of the heel. The pain may be worse when the doctor bends the ankle upward (dorsiflex), as this may tighten the achilles tendon over the inflamed bursa. Alternatively, the pain may be worse with toe rise, as this puts stress on the attachment of the achilles tendon to the heel bone. Imaging studies such as X-ray and MRI are not usually necessary at first. If initial treatment fails to improve the symptoms, these studies may be obtained. MRI may show inflammation.
Non Surgical Treatment
Conservative treatment of bursitis is usually effective. The application of heat, rest, and immobilization of the affected joint area is the first step. A sling can be used for a shoulder injury, a cane is helpful for hip problems. The patient can take nonsteroidal anti-inflammatory drugs (NSAIDs) like aspirin, ibuprofin, and naproxen. They can be obtained without a prescription and relieve the pain and inflammation. Once the pain decreases, exercises of the affected area can begin. If the nearby muscles have become weak because of the disease or prolonged immobility, then exercises to build strength and improve movement are best. A doctor or physical therapist can prescribe an effective regimen. If the bursitis is related to an inflammatory condition like arthritis or gout, then management of that disease is needed to control the bursitis. When bursitis does not respond to conservative treatment, an injection into the joint of a long-acting corticosteroid preparation, like prednisone, can bring immediate and lasting relief. A corticosteroid is a hormonal substance that is the most effective drug for reducing inflammation. The drug is mixed with a local anesthetic and works on the joint within five minutes. Usually one injection is all that is needed.
Bursectomy is a surgical procedure used to remove an inflamed or infected bursa, which is a fluid-filled sac that reduces friction between tissues of the body. Because retrocalcaneal bursitis can cause chronic inflammation, pain and discomfort, bursectomy may be used as a treatment for the condition when it is persistent and cannot be relived with other treatments. During this procedure, a surgeon makes small incisions so that a camera may be inserted into the joint. This camera is called an arthroscope. Another small incision is made so that surgical instruments can be inserted to remove the inflamed bursa.
Maintain proper form when exercising, as well as good flexibility and strength around the ankle to help prevent this condition. Proper stretching of the Achilles tendon helps prevent injury.
