A bursa is a closed, fluid-filled sac that functions as a cushion and gliding surface to reduce friction between tissues of the body. The major bursae are located adjacent to the tendons near the large joints, such as in the shoulders, elbows, hips, and knees. When the bursa becomes inflamed, the condition is known as bursitis. Bursitis is usually a temporary condition. It may restrain motion, but generally does not cause deformity.
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.
Common signs and symptoms associated with infracalcaneal bursitis include redness under the heel. Pain and swelling under the heel. Pain or ache in the middle part of the underside of the heel. Heel pain or discomfort that increases with prolonged weight-bearing activities.
The diagnosis is based on the symptoms and an examination. For anterior Achilles tendon bursitis, doctors use x-rays to rule out a fracture of the heel bone or damage to the heel bone caused by rheumatoid arthritis or other inflammatory arthritis.
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.
