Bursitis is inflammation or irritation of a bursa, a small sac located between a bone and muscle, skin, or tendon. The bursa allows smooth gliding between these structures. Below are some of the specific types of bursitis. Subacromial bursitis The subacromial bursa lies just above the rotator cuff. Bursitis often develops due to injury, impingement (pinching), overuse of the shoulder, or calcium deposits. Symptoms include pain in the upper shoulder or upper third of the arm, and severe pain upon moving the shoulder.
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.
Bursitis usually causes a dull pain, tenderness, and stiffness near the affected bursa. The bursa may swell and make the skin around it red and warm to the touch. Bursitis is most common in the shoulder camera.gif, elbow camera.gif, hip camera.gif, and knee camera.gif. Bursitis may also occur near the Achilles tendon or in the foot. Symptoms of bursitis may be like those of tendinopathy. Both occur in the tissues in and around the joints. Check with your doctor if your pain is severe, if the sore area becomes very hot or red, or if you have a fever.
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
Over-the-counter or custom heel wedges may help to decrease the stress placed on the attachment of the achilles tendon and the associated bursa. If these interventions are ineffective, then some health care providers may inject a small amount of steroids into the bursa. If the condition is associated with Achilles tendonitis, then casting the ankle to prevent motion for several weeks can be effective. Very rarely, surgery may be necessary to remove the inflamed bursa.
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.
