Retrocalcaneal bursitis is the inflammation of the fluid-filled sac (bursa) at the back of the heel bone (calcaneus). The retrocalcaneal bursa is located between the Achilles tendon and the heel bone and is designed to reduce friction between the Achilles tendon and the heel bone. During contraction of the calf muscle, tension is generated through the Achilles tendon and it rubs against the retrocalcaneal bursa. When there is excessive friction due to repetitive rubbing of the tendon against the bursa or high impact force translating through the Achilles tendon, irritation and inflammation of the bursa may occur. The inflammation can also be aggravated by pressure, such as when athletes wear tight-fitting shoes. This condition is often mistaken for Achilles tendinitis but it can also occur in conjunction with Achilles tendinitis.
The calcaneal bursa can become inflamed in patients with heel spurs or in patients with poor-fitting shoes (eg, high heels). Inflammation can occur secondarily from Achilles tendinitis, especially in young athletes. Patients exhibit tenderness to palpation of the bursa anterior to the Achilles tendon on both the medial and lateral aspects. They have pain with movement, which is worsened with dorsiflexion.
Where the tendon joins the calcaneal bone, friction can cause the spaces between the tendon, bone and skin to swell and inflame with bursitis. This constitutes a calcaneal bursa. Apart from swelling over the back of the heel, you?ll feel acute tenderness and pain when you move it or even apply light pressure. Your swollen heel may look more red than the other one, and the swelling is often so hard it can feel like bone, partly because it sometimes is, as a bony overgrowth can occur in chronic cases.
A physical examination will be performed to determine if you have any signs of Achilles Bursitis or other ankle injury. He/she will look and feel the soft tissue and bones in your ankles to note any differences between the two of them. This will identify any abnormalities, such as swelling, bone deformities, atrophied muscles, redness and/or warmth on the skin. In many cases, the first sign that you have Achilles bursitis is swelling in the back of the foot and ankle pain.
Non Surgical Treatment
The initial course of treatment for this problem, after the usual ice and ibuprofen/aspirin routine or course, is to change footwear, especially if the onset of the problem was coincidental with a new pair of shoes. If this fails, a small heel lift (no more than ??) in both shoes may provide enough biomechanical adjustment to relieve the stress and/or friction over the area. If there is still no improvement, complete rest from running is probably advised, along with a professional consultation.
Surgery to remove the damaged bursa may be performed in extreme cases. If the bursitis is caused by an infection, then additional treatment is needed. Septic bursitis is caused by the presence of a pus-forming organism, usually staphylococcus aureus. This is confirmed by examining a sample of the fluid in the bursa and requires treatment with antibiotics taken by mouth, injected into a muscle or into a vein (intravenously). The bursa will also need to be drained by needle two or three times over the first week of treatment. When a patient has such a serious infection, there may be underlying causes. There could be undiscovered diabetes, or an inefficient immune system caused by human immunodeficiency virus infection (HIV).
Because many soft tissue conditions are caused by overuse, the best treatment is prevention. It is important to avoid or modify the activities that cause problems. Underlying conditions such as leg length differences, improper position or poor technique in sports or work must be corrected. Be aware of potential overuse or injury in your daily activities and change your lifestyle to prevent problems. Otherwise, problems may persist or occur repeatedly. Following are some ways you can avoid future problems. Wear walking or jogging shoes that provide good support. High-top shoes provide support for people with ankle problems. Wear comfortable shoes that fit properly. Wear heel cups or other shoe inserts as recommended by your doctor. Exercise on level, graded surfaces.
