Retrocalcaneal bursitis is an inflammation or infection of the bursae at the back of the heel bone. Bursae are fluid-filled sacs that cushion the joints and prevent the bones from becoming injured due to friction. Because this condition can cause pain and difficulty moving, getting treatment is important. There are several retrocalcaneal bursitis treatment options available. Patients and physicians should work together to determine the best treatment based on the symptoms and severity of the condition.
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.
Some of the symptoms of bursitis in the heel, or retrocalcaneal bursitis, are as described below. Severe pain in the heel area of the foot, sometimes radiating to the ankle, associated with physical activities like walking, jogging and even on physical contact to the area. The physical signs of heel bursitis, which are noticeable in the heel area, are reddish discoloration of the skin that is warm to touch.
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.
Maintain proper form when exercising, as well as good flexibility and strength around the ankle to help prevent this condition. Proper stretching of the Achilles tendon helps prevent injury.
