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.
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.
What are the symptoms of heel bursitis? pain, swelling, tenderness, redness, and/or warmth at either the bottom of the heel or top of the heel, depending on the degree of swelling, pain may be a dull ache or substantial enough to cause limping, running, jumping, and walking activities may exacerbate pain, wearing poorly fitting, tight, or high-heeled shoes may exacerbate pain.
In addition to a complete medical history and physical examination, diagnostic procedures for bursitis may include the following. X-ray. A diagnostic test that uses invisible electromagnetic energy beams to produce images of internal tissues, bones, and organs onto film. Magnetic resonance imaging (MRI). A diagnostic procedure that uses a combination of large magnets, radiofrequencies, and a computer to produce detailed images of organs and structures within the body. Ultrasound. A diagnostic technique that uses high-frequency sound waves to create an image of the internal organs. Aspiration. A procedure that involves removal of fluid from the swollen bursa to exclude infection or gout as causes of bursitis. Blood tests. Lab tests that are done to confirm or eliminate other conditions.
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 is rarely done strictly for treatment of a bursitis. If any underlying cause is the reason, this may be addressed surgically. During surgery for other conditions, a bursa may be seen and removed surgically.
