Retrocalcaneal bursitis is a condition characterized by tissue damage and inflammation of the retrocalcaneal bursa (a small fluid filled sac located at the back of the heel) causing pain in the heel region. A bursa is a thin fluid filled sac found in various places throughout the body. Bursae are designed to reduce friction between adjacent layers of tissue and are filled with lubricating fluid. They are typically located in regions of the body where tissue layers may rub against each other or against bony prominences The muscle group at the back of the lower leg is commonly called the calf. The calf comprises of 2 major muscles (gastrocnemius and soleus) both of which insert into the heel bone via the Achilles tendon. Between the Achilles tendon and the heel bone lies a bursa known as the retrocalcaneal bursa.
If the posterior-superior portion of the heel has an abnormally large bony prominence protruding from it (called a Haglund's Deformity), in some instances it may rub against the Achilles Tendon. When this occurs, the bursa between the bone and the tendon will become inflamed, swollen, and painful. This condition is called Retrocalcaneal Bursitis. The presence of a Haglund's Deformity does not insure that these problems will occur. In order for these problems to occur, the heel and foot must be tilted in such a way as to actually force this bony prominence into the bursa and tendon.
Limping. Decreased movement. Your ankles may feel stiff or unable to move as well as they usually do. Pain or tenderness in the back of the ankle. It may be worse at the beginning of exercise, or when running uphill. You may also have pain when wearing shoes. Redness and warmth. If the bursa is infected, the skin over the heel may be red and warm. You may also have a fever. Swelling on the back of the heel.
Magnetic resonance imaging (MRI) may demonstrate bursal inflammation, but this modality probably does not offer much more information than that found by careful physical examination. Theoretically, MRI could help the physician to determine whether the inflammation is within the subcutaneous bursa, the subtendinous bursa, or even within the tendon itself, however, such testing is generally not necessary. Ultrasonography may be a potentially useful tool for diagnosing pathologies of the Achilles tendon.
Non Surgical Treatment
If not properly treated, a case of bursitis can turn into chronic bursitis, flaring up on and off for several weeks or longer. Bursitis treatment involves resting the joint, often combined with other methods to alleviate swelling, including NSAIDs (e.g. Aleve, ibuprofen), icing the joint, elevating the joint, and wrapping the joint in an elastic bandage. Cases of septic bursitis must also be treated with antibiotics to prevent the infection from spreading to other parts of the body or into the bloodstream.
After taking a history and performing a physical examination, your physician may order x-rays to rule out other disorders. Your doctor may administer injections of corticosteroids and a local anesthetic to reduce swelling and ease pain. Also, to reduce swelling, your physician may draw excess fluid from the bursa with a syringe and then tightly wrap and compress the joint with an elastic bandage. In severe, persistent cases surgery to remove the bursa may be necessary. For infectious bursitis, antibiotics will be prescribed.
