Overview
Retrocalcaneal bursitis is the painful inflammation and swelling of the retrocalcaneal bursa that is situated between the calcaneus (heel bone) and the Achilles tendon. A bursa is a small fluid filled sac that forms around joints in areas where there is a lot of friction between muscles, tendons and outcrops of bone. The bursae position themselves in between the tendon or muscle and the bone, buffering any friction from movement. To picture a bursa imagine it as a very small water filled balloon that sits in places where things rub against each other, such as in between a tendon and a bone, to provide a soft smooth cushion for the tendon to pass over painlessly. The covering of the bursa also acts as a lubricant and aids the tendon?s movement. It is estimated that there is over 150 bursae in your body which protect the joint and tendons from wear. They are all very small and unnoticeable until they become swollen and painful with bursitis.
Causes
Retrocalcaneal bursitis is generally caused by local trauma from poorly designed shoes. Patients complain of posterolateral heel pain and may have a posterior heel prominence (?pump bump?), as well as local swelling and tenderness over the Achilles tendon. Pain is increased by squeezing the bursa from side to side and anterior to the Achilles. A heel lift and open-back shoes help alleviate pressure.
Symptoms
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.
Diagnosis
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
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.
Surgical Treatment
Surgery to remove the damaged bursa may be performed in extreme cases. If the bursitis is caused by an infection, then additional treatment is needed. Septic bursitis is caused by the presence of a pus-forming organism, usually staphylococcus aureus. This is confirmed by examining a sample of the fluid in the bursa and requires treatment with antibiotics taken by mouth, injected into a muscle or into a vein (intravenously). The bursa will also need to be drained by needle two or three times over the first week of treatment. When a patient has such a serious infection, there may be underlying causes. There could be undiscovered diabetes, or an inefficient immune system caused by human immunodeficiency virus infection (HIV).
