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.
Repetitive, vigorous movement, strenuous and unaccustomed activities that put pressure on a joint, or a blow or other injury can bring on bursitis. The cause can vary depending on where the bursitis occurs. In the shoulder, for example, it can be brought on by excessive strain, such as from serving in tennis. Kneeling on a hard floor can cause bursitis of the knee, and similarly, repeatedly resting the elbow on a hard surface (such as a desk) can cause bursitis in that joint. Arthritis, gout, and certain infections can also contribute to the problem. Bursitis, in fact, may signal the onset of arthritis. While getting older isn’t a cause of bursitis, older people, especially older athletes, are more likely to develop the condition.
Pain at the back of the heel, especially when running uphill. Pain may get worse when rising on the toes (standing on tiptoes). Tenderness at the back of heel. Swelling at the back of heel.
Gram stain. A lab test called a Gram stain is used to determine if certain troublesome bacteria are present. Not all bacteria can be identified with a Gram stain, however, so even if the test comes back negative, septic bursitis cannot be completely ruled out. White blood cell count. An elevated number of white blood cells in the bursa’s synovial fluid indicates an infection. Glucose levels test. Glucose levels that are significantly lower than normal may indicate infection.
Non Surgical Treatment
Relieving the symptoms of bursitis initially focuses on taking the pressure off the bursa. This can be done with proper cushioning, inserts, or footwear but may require surgery if it is a bone formation problem (i.e. Huglund’s Deformity). If your bursitis is caused by an infection (septic bursitis), the doctor will probably drain the bursa sac with a needle and prescribe antibiotics to treat the infection.
Bursectomy is a surgical procedure used to remove an inflamed or infected bursa, which is a fluid-filled sac that reduces friction between tissues of the body. Because retrocalcaneal bursitis can cause chronic inflammation, pain and discomfort, bursectomy may be used as a treatment for the condition when it is persistent and cannot be relived with other treatments. During this procedure, a surgeon makes small incisions so that a camera may be inserted into the joint. This camera is called an arthroscope. Another small incision is made so that surgical instruments can be inserted to remove the inflamed bursa.
