Bursa is a fluid filled sac of tissue that is often found around the bony prominences over which tendons and soft tissues rub. This therefore helps the tendons to glide with least amount of friction. Retrocalcaneal bursa is found behind the heel under the Achilles tendon. Retrotendoneal bursa is found on the back of the attachment of the tendon where the shoe rubs on the skin. This can cause swelling, pain and difficulty in footwear. Sometimes there is a bony prominence on the heel bone that predisposes to this condition (Haglund?s deformity). Treatment of this can be modification of footwear. However surgery is often required which involves excision of the bursa and also the bony prominence on the heel bone.
A bursa is a fluid-filled sac that acts as a cushion and a lubricant between tendons and muscles sliding over bone. There are bursas around most large joints in the body, including the ankle. The retrocalcaneal bursa is located in the back of the ankle by the heel, where the large Achilles tendon connects the calf muscles to the heel bone (calcaneus). Repetitive or over use of the ankle, for instance by doing excessive walking, running or jumping, can cause this bursa to become irritated and inflamed. This condition is commonly associated with Achilles tendonitis. Sometimes retrocalcaneal bursitis may be mistaken for achilles tendonitis. Those at risk for this condition include people just starting aggressive exercise regimens or having some other sudden increase in activity without proper conditioning.
Pain at the back of the heel at the attachment site of the Achilles tendon when running. Pain on palpation of the back of the heel or bottom of heel. Pain when standing on tiptoes. Swelling and redness at the back and bottom of the heel.
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
The following exercises are commonly prescribed to patients with retrocalcaneal bursitis. You should discuss the suitability of these exercises with your physiotherapist prior to beginning them. Generally, they should be performed 2, 3 times daily and only provided they do not cause or increase symptoms. Your physiotherapist can advise when it is appropriate to begin the initial exercises and eventually progress to the intermediate, advanced and other exercises. As a general rule, addition of exercises or progression to more advanced exercises should take place provided there is no increase in symptoms. Move your foot and ankle up and down as far as you can go without pain and provided you feel no more than a mild to moderate stretch. Repeat 10, 20 times provided there is no increase in symptoms. Move your foot and ankle in and out as far as you can go without pain and provided you feel no more than a mild to moderate stretch. Repeat 10, 20 times provided there is no increase in symptoms. Move your foot and ankle in a circle as large as you can go without pain and provided you feel no more than a mild to moderate stretch. Repeat 10, 20 times in both clockwise and anticlockwise directions provided there is no increase in symptoms. Calf Stretch with Towel. Begin this stretch in long sitting with your leg to be stretched in front of you. Your knee and back should be straight and a towel or rigid band placed around your foot as demonstrated. Using your foot, ankle and the towel, bring your toes towards your head as far as you can go without pain and provided you feel no more than a mild to moderate stretch in the back of your calf, Achilles tendon or leg. Hold for 5 seconds and repeat 10 times at a mild to moderate stretch provided the exercise is pain free.
Surgery is rarely done strictly for treatment of a bursitis. If any underlying cause is the reason, this may be addressed surgically. During surgery for other conditions, a bursa may be seen and removed surgically.
