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.
The inflammation of a bursa can result from any process that irritates or compresses it. The irritation causes the affected bursa to produce too much fluid and swell. In cases of traumatic injury, injured capillaries can leak blood into the bursa and cause it to swell.
Pain and tenderness usually develop slowly over time. Applying pressure to the back of the heel can cause pain. Wearing shoes may become uncomfortable. The back of the heel may feel achy. Pain is exacerbated when the foot is pointed or flexed, because the swollen bursa can get squeezed. A person with retrocalcaneal bursitis may feel pain when standing on their toes. Fever or chills in addition to other bursitis symptoms can be a sign of septic bursitis. Though uncommon, septic retrocalcaneal bursitis is a serious condition, and patients should seek medical care to ensure the infection does not spread.
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
Treatments should involve decreasing swelling, relieving pain and stress on the Achilles, correcting any biomechanical dysfunction (over-pronation or flat feet), treating scar tissue, and then restoring strength and movement. If you are performing an activity that could cause further trauma to the bursa, it is recommended that you protect the area with padding and/or proper footwear to prevent further irritation or damage.
You can help to prevent heel pain and bursitis by maintaining a healthy weight, by warming up before participating in sports and by wearing shoes that support the arch of the foot and cushion the heel. If you are prone to plantar fasciitis, exercises that stretch the Achilles tendon (heel cord) and plantar fascia may help to prevent the area from being injured again. You also can massage the soles of your feet with ice after stressful athletic activities. Sometimes, the only interventions needed are a brief period of rest and new walking or running shoes.
