The Achilles tendon is the large tendon that connects the calf muscles to the heel bone (calcaneus) and is used when you walk, run and jump.
Achilles tendon bursitis or retrocalcaneal bursitis is a condition that commonly occurs in athletes. It is a painful condition caused by the swelling of the bursa, a fluid-filled sac that is located at the back of the heel under the Achilles tendon. This retrocalcaneal bursa contains a lubricating fluid that acts as a cushion to reduce friction between muscle and bones.
Achilles tendon bursitis is caused by overuse of the ankle from excessive walking, jumping or running, which results in irritation and inflammation of the bursa. Achilles tendon bursitis can also occur in conjunction with Achilles tendinitis, which is the inflammation of the Achilles tendon.
Children who suddenly increase their level of physical activity are at a higher risk of developing Achilles tendon bursitis.
The most common symptom of Achilles tendon bursitis is pain and tenderness at the back of the heel, especially while walking or running. Pain increases when standing on tiptoes. In some cases, the skin at the back of the heel may become warm and red.
Your doctor may diagnose the condition based on the symptoms and physical examination of the ankle. Diagnostic tests such as X-rays and MRI scans may be required later if the treatment does not improve the symptoms.
The initial treatment for Achilles tendon bursitis includes:
Surgery is considered only when all non-surgical treatment fails to resolve pain and inflammation. Bursectomy is a surgical procedure performed to remove an inflamed or infected bursa.
Achilles tendon bursitis may be prevented by observing proper form during sports and exercise. Ensure that you warm up before the start of any sports activity to help prevent injury of the Achilles tendon.
