Bursitis happens when the bursa is inflamed. The burse acts as a cushion between bones, tendons, joints and muscles, bursae are fluid-filled sacs (the plural of bursa is bursae). People with bursitis
will feel pain at the site of inflammation. The medical word "bursa" comes from the Latin bursa, meaning a purse, which is what a bursa resembles.
Wearing poorly fitting or constrictive footwear can cause the heel to become irritated and inflamed. Shoes that dig into the back of the heel are the primary cause of retroachilles bursitis. Foot or
ankle deformity. A foot or ankle deformity can make it more likely to develop retrocalcaneal bursitis. For example, some people can have an abnormal, prominent shape of the top of their heel, known
as a Haglund's deformity. This condition increases the chances of irritating the bursa. A trauma to the affected heel, such as inadvertently striking the back of the heel against a hard object, can
cause the bursa to fill with fluid, which in turn can irritate and inflame the bursa's synovial membrane. Even though the body usually reabsorbs the fluid, the membrane may stay inflamed, causing
The signs and symptoms of heel bursitis can include heel pain wearing particular footwear, Pain or discomfort in the heel when walking, jogging or running, Swelling or inflammation in the heel.
If heel pain has not responded to home treatment, X-rays may be ordered. These images can show deformities of the heel bone and bone spurs that have developed at the attachment of the Achilles. If
there is swelling and/or pain that is slightly higher and within the Achilles tendon itself, an MRI may be ordered to determine if the tendon is simply inflamed or if there is a chronic tear on the
tendon. Aspiration and lab tests. If a septic bursitis is highly suspected, a doctor may perform an aspiration, removing fluid from the bursa with a needle and syringe. In addition to relieving
pressure and making the patient more comfortable, it provides a fluid sample that can be tested for infection.
Non Surgical Treatment
Many cases of retrocalcaneal bursitis can be resolved with self-care that is focused on reducing inflammation and eliminating activities or positions that aggravate the bursa. Some cases, however,
may become more serious and require more medical interventions. Rarely, surgery is needed. Following the R.I.C.E. formula, or Rest, Ice, Compression, and Elevation, is often sufficient to treat
aseptic bursitis. Rest. People with retrocalcaneal bursitis should avoid activities that irritate the bursa, such as jogging or excessive walking. Ice. Applying a cold compress to the back of the
ankle for about 20 minutes two or three times a day may help alleviate symptoms and decrease swelling. Compression. An elastic medical bandage (e.g. Ace? bandage) wrapped around the affected heel and
ankle can help control swelling. Elevating the affected heel. Sitting down with the leg elevated on a stool or lying down with the foot elevated on a pillow can help reduce blood flow to the area,
thereby reducing inflammation.
Surgery. Though rare, particularly challenging cases of retrocalcaneal bursitis might warrant a bursectomy, in which the troublesome bursa is removed from the back of the ankle. Surgery can be
effective, but operating on this boney area can cause complications, such as trouble with skin healing at the incision site. In addition to removing the bursa, a doctor may use the surgery to treat
another condition associated with the retrocalcaneal bursitis. For example, a surgeon may remove a sliver of bone from the back of the heel to alter foot mechanics and reduce future friction. Any
bone spurs located where the Achilles attaches to the heel may also be removed. Regardless of the conservative treatment that is provided, it is important to wait until all pain and swelling around
the back of the heel is gone before resuming activities. This may take several weeks. Once symptoms are gone, a patient may make a gradual return to his or her activity level before their bursitis
symptoms began. Returning to activities that cause friction or stress on the bursa before it is healed will likely cause bursitis symptoms to flare up again.
