Bursitis Of The Foot Physiology

Overview
Retrocalcaneal Bursitis. This bursa is located at the back of the heel. Bursitis in this area is often associated with conditions such as ankylosing spondylitis or rheumatoid arthritis. It can occur in healthy individuals who wear improperly fitted shoes. Symptoms include painful swelling that develops at the back of the heel. Calcaneal Bursitis. This bursa is located at the sole or bottom of the heel. Inflammation usually produces pain in the heel when standing. Causes include heel spurs, excess weight, injury, and wearing improperly fitted shoes.

Causes
Bursitis is caused by overuse or excessive pressure on the joint, injury, infection, or an underlying condition, such as osteoarthritis, rheumatoid arthritis, gout, pseudogout, or ankylosing spondylitis. When bursitis is caused by an underlying condition, the condition must be treated along with the bursitis. When bursitis is caused by infection, called septic bursitis, medical treatment and antibiotics are necessary.

Symptoms
Symptoms of bursitis usually occur after rest and relaxation. Upon activity there is usually more intense pain in the area of the bursa. The common areas to have a bursitis in the foot are in the bottom of the heel, behind the heel near the attachment of the Achilles Tendon as well as along the side of a bunion. A bursa may also form in multiple areas especially along the metatarsal heads, or "ball" of your foot. You may actually feel the sac like fluid when rubbing the area of pain.

Diagnosis
Your health care provider will take a history to find out if you have symptoms of retrocalcaneal bursitis. Examining your ankle can find 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). Or, the pain may be worse when you rise on your toes. You will not usually need imaging studies such as x-ray and MRI at first. If the first treatment does not improve the symptoms, your health care provider may recommend these tests. MRI may show inflammation.

Non Surgical Treatment
Your health care provider may recommend the following treatments. Avoid activities that cause pain. Ice the heel several times a day. Take nonsteroidal anti-inflammatory medications (for example, ibuprofen). Try over-the-counter or custom heel wedges to help decrease the stress on the heel. Try ultrasound treatment during physical therapy to reduce inflammation. Use physical therapy to improve flexibility and strength around the ankle, which can help the bursitis improve and prevent it from coming back. If these treatments don't work, your health care provider may inject a small amount of steroids into the bursa. After the injection, you should avoid stretching the tendon too much because it can break open (rupture). If the condition is connected with Achilles tendinitis, casting the ankle for several weeks to keep it from moving can be effective. Very rarely, surgery may be needed to remove the inflamed bursa.

Surgical Treatment
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.

Prevention
Maintain proper form when exercising, good flexibility, and strength around the ankle to help prevent this condition from arising. Proper stretching of the achilles tendon helps prevent injury.
