Retrocalcaneal bursitis is closely related to Haglund?s Deformity (or ?pump bumps?). If you have a bony enlargement on the back of the heel that rubs the Achilles tendon, it can cause the formation of a bursa (small fluid filled sack). It usually happens in athletes as shoes rub against the heel. The bursa can aggravated by the stitching of a heel counter in the shoe as well. It can make wearing shoes and exercising difficult. Another term used for this condition is ?pump bump? because it can frequently occur with wearing high heels as well. ?Retro-" means behind and ?calcaneus? means heel bone. So this is precisely where the bursitis (inflammation of the bursa) develops. Once it begins and you develop bursitis between the heel bone and the Achilles tendon, it can become even more painful. When most people first notice retrocalcaneal bursitis, it is because the skin, bursa and other soft tissues at the back of the heel gets irritated as the knot of bone rubs against the heel counter in shoes. The back of the shoes create friction and pressure that aggravate the bony enlargement and pinches the bursa while you walk.
Normally, only one bursa is in the heel, between the Achilles tendon and the heel bone (calcaneus). This bursa may become inflamed, swollen, and painful, resulting in anterior Achilles tendon bursitis. Abnormal pressure and foot dysfunction can cause a protective bursa to form between the Achilles tendon and the skin. This bursa may also become inflamed, swollen, and painful, resulting in posterior Achilles tendon bursitis.
Pain or tenderness at the back of the heel around the Achilles region. Increased pain during activities with strong, repetitive calf contractions, walking (uphill), stair climbing, running, jumping. Pain may be worse with rest after activity (that night or the next morning) or at the beginning of the excercise. Pain when wearing shoes and the heel is getting rubbed. Bump forming on the back of the heel. Limping. Stiffness. Decreased range of motion. Redness and warmth (if the bursa gets infected).
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 patient with retrocalcaneal bursitis should be instructed to apply ice to the posterior heel and ankle in the acute period of the bursitis. Icing can be performed several times a day, for 15-20 minutes each. Some clinicians also advocate the use of contrast baths. Gradual progressive stretching of the Achilles tendon may help relieve impingement on the subtendinous bursa and can be performed in the following manner. Stand in front of a wall, with the affected foot flat on the floor. Lean forward toward the wall until a gentle stretching is felt within the ipsilateral Achilles tendon. Maintain the stretch for 20-60 seconds and then relax. Perform the stretches with the knee extended and then again with the knee flexed. To maximize the benefit of the stretching program, repeat the above steps for several stretches per set, several times daily. Avoid ballistic (ie, abrupt, jerking) stretches. Other treatment options are microcurrent therapy and corticosteriod injection into the retrocalcaneal bursa. If conservation treatment fails then surgery is indicated.
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.
