A bursa is a small sack of fluid that sits between a tendon and a bone to help the tendon move smoothly over the bone. The retrocalcaneal bursa in situated in the feet between the Achilles tendon and the calcaneus or heel bone. With repeated trauma the bursa can become inflamed. Achilles tendon bursitis is often mistaken for achilles tendinitis. It is possible for the athlete to have both achilles tendinitis and achilles tendon bursitis at the same time which is known as Haglund's syndrome.
The most common causes of bursitis are injury or overuse, although infection may also be a cause. Bursitis is also associated with other causes, such as arthritis, gout, tendinitis, diabetes, and thyroid disease.
Medical experts strongly recommend that you consult a doctor if you have any of the symptoms below. Disabling joint pain that prevents you from doing your daily activities. Pain that lasts for more than two weeks. Excessive swelling, redness, bruising or a rash around the painful joint. Sharp or shooting pain, especially when you exercise or do something more strenuous. A fever. Any of the above could be a sign of infection, a condition such as arthritis or a more serious injury such as a tendon tear that may require medical attention.
The doctor will discuss your symptoms and visually assess the bones and soft tissue in your foot. If a soft tissue injury is suspected, an MRI will likely be done to view where and how much the damage is in your ankle. An x-ray may be recommended to rule out a bone spur or other foreign body as the cause of your ankle pain. As the subcutaneous bursa is close to the surface of the skin, it is more susceptible to septic, or infectious, bursitis caused by a cut or scrape at the back of the heel. Septic bursitis required antibiotics to get rid of the infection. Your doctor will be able to determine whether there is an infection or not by drawing a small sample of the bursa fluid with a needle.
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.
Only if non-surgical attempts at treatment fail, will it make sense to consider surgery. Surgery for retrocalcanel bursitis can include many different procedures. Some of these include removal of the bursa, removing any excess bone at the back of the heel (calcaneal exostectomy), and occasionally detachment and re-attachment of the Achilles tendon. If the foot structure and shape of the heel bone is a primary cause of the bursitis, surgery to re-align the heel bone (calcaneal osteotomy) may be considered. Regardless of which exact surgery is planned, the goal is always to decrease pain and correct the deformity. The idea is to get you back to the activities that you really enjoy. Your foot and ankle surgeon will determine the exact surgical procedure that is most likely to correct the problem in your case. But if you have to have surgery, you can work together to develop a plan that will help assure success.
