Bursitis Of The Foot Physiology

Overview
Retrocalcaneal Bursitis. This bursa is located at the back of the heel. Bursitis in this area is often associated with conditions such as ankylosing spondylitis or rheumatoid arthritis. It can occur in healthy individuals who wear improperly fitted shoes. Symptoms include painful swelling that develops at the back of the heel. Calcaneal Bursitis. This bursa is located at the sole or bottom of the heel. Inflammation usually produces pain in the heel when standing. Causes include heel spurs, excess weight, injury, and wearing improperly fitted shoes.

Causes
The retrocalcaneal bursa can become inflamed as the result of another condition, such as damage to the Achilles tendon, osteoarthritis, rheumatoid arthritis, gout, and pseudogout. In these instances, the treatment for bursitis must accompany treatment for the underlying condition. Septic retrocalcaneal bursitis, which is caused by an infection, is uncommon. Infection can reach the bursa through a cut, puncture, a blister, or even an insect bite. It is possible to have septic bursitis without an obvious opening. In these cases the superficial wound may have healed quickly, but still allowed bacteria into the bursa.

Symptoms
Symptoms include pain at the back of the heel, especially when running uphill or on soft surfaces. There will be tenderness and swelling at the back of the heel which may make it difficult to wear certain shoes. When pressing in with the fingers both sides are the back of the heel a spongy resistance may be felt.

Diagnosis
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
In addition to R.I.C.E., there are a number of other treatments to reduce swelling and any associated pain or discomfort due to heel bursitis. Orthotics or change of footwear. Wearing an orthotic device such as a heel insert can encourage better mechanics in the foot and reduce irritation of the retrocalcaneal bursa. Some people do not need special orthotics but simply need to stop wearing shoes with rigid heel and ankle construction and instead wear more supportive, comfortable shoes. Shoes with an "Achilles notch," a groove in the collar at the back of the shoe to protect the Achilles tendon, can be particularly helpful. (Almost all running shoes are designed with an Achilles notch.) Stretching and physical therapy. Stretching the Achilles tendon often helps alleviate pain. Once the pain is resolved it is important for the patient to continue a regular stretching program. Regular stretching reduces the chance of recurrence.

Surgical Treatment
Only if non-surgical attempts at treatment fail, will it make sense to consider surgery. Surgery for retrocalcanel bursitis can include many different procedures. Some of these include removal of the bursa, removing any excess bone at the back of the heel (calcaneal exostectomy), and occasionally detachment and re-attachment of the Achilles tendon. If the foot structure and shape of the heel bone is a primary cause of the bursitis, surgery to re-align the heel bone (calcaneal osteotomy) may be considered. Regardless of which exact surgery is planned, the goal is always to decrease pain and correct the deformity. The idea is to get you back to the activities that you really enjoy. Your foot and ankle surgeon will determine the exact surgical procedure that is most likely to correct the problem in your case. But if you have to have surgery, you can work together to develop a plan that will help assure success.

Prevention
Do not run if you have pain. When you begin running again, avoid running fast uphill or downhill until the tendon is fully healed. Start exercising when caregivers say that it is OK. Slowly start exercise such as bicycling when caregivers say it is OK. When doing exercises that put pressure on the ankles, such as running or walking, exercise on flat, even surfaces. Avoid doing these exercises on very hard surfaces such as asphalt or concrete. Stretch before exercising. Always warm up your muscles and stretch gently before exercising. Do cool down exercises when you are finished. This will loosen your muscles and decrease stress on your heel. Wear heel protectors. Use soft foam or felt heel pads (wedges or cups) to help decrease pressure against your heel. Ask your caregiver which heel pads are the best for you. Wear well-fitting shoes. Buy running or exercise shoes that support and fit your feet well. Do not wear low-cut shoes. Talk to your caregiver or go to a special exercise footwear store to get well-fitting athletic shoes. Ask your caregiver if you should wear specially-made shoe inserts called orthotics (or-THOT-iks). Orthotics can line up your feet in your shoes to help you run, walk and exercise correctly.
