Overview
There are two main bursae involved in heel bursitis, the subtendinous calcaneal bursa and the subcutaneous calcaneal bursa. Both of these bursa are located near the Achilles tendon. The subtendinous calcaneal bursa, which is also referred to as the retrocalcaneal bursa, is on the back of the heel and is deeply situated between the Achilles tendon and the calcaneus. The subcutaneous calcaneal bursa, which is commonly referred to as the Achilles bursa, is located near the bottom of the heel between the skin and the distal aspect of the Achilles tendon. It?s much more superficial to the Achilles tendon than the subtendinous calcaneal bursa.
Causes
Although rare, bursitis also may be caused by an infection, known as septic bursitis. This is a serious medical condition that requires antibiotics to treat the infection and prevent its spread to other points in the body or the bloodstream. Septic bursitis may cause the back of the ankle to become red or hot. The person may also get the chills or fever and may feel sick and tired. Typically this type of bursitis would be suspected if there has been any history of an open wound in the area, such as a blister.
Symptoms
Limping. Decreased movement. Your ankles may feel stiff or unable to move as well as they usually do. Pain or tenderness in the back of the ankle. It may be worse at the beginning of exercise, or when running uphill. You may also have pain when wearing shoes. Redness and warmth. If the bursa is infected, the skin over the heel may be red and warm. You may also have a fever. Swelling on the back of the heel.
Diagnosis
Magnetic resonance imaging (MRI) may demonstrate bursal inflammation, but this modality probably does not offer much more information than that found by careful physical examination. Theoretically, MRI could help the physician to determine whether the inflammation is within the subcutaneous bursa, the subtendinous bursa, or even within the tendon itself, however, such testing is generally not necessary. Ultrasonography may be a potentially useful tool for diagnosing pathologies of the Achilles tendon.
Non Surgical Treatment
Non-operative treatment is the standard approach to treating posterior heel pain. It is highly desirable to treat this condition non-operatively, as operative treatment is often associated with a prolonged recovery. Traditional non-operative treatment includes the following. Heel Lift or the Use of a Shoe with a Moderate Heel. Walking barefoot or in a flat-soled shoe increases the tension on the insertion of the Achilles tendon. Using a heel lift or a shoe with a moderate heel can help reduce the stress on the tendon and decrease the irritation caused by this condition.
Surgical Treatment
Surgery is rarely done strictly for treatment of a bursitis. If any underlying cause is the reason, this may be addressed surgically. During surgery for other conditions, a bursa may be seen and removed surgically.
Prevention
It isn’t always possible to avoid the sudden blow, bump, or fall that may produce bursitis. But you can protect your body with measures similar to those that protect you from other kinds of overuse injuries, such as tendinitis. Keep yourself in good shape. Strengthening and flexibility exercises tone muscles that support joints and help increase joint mobility. Don?t push yourself too hard (or too long). If you?re engaged in physical labor, pace yourself and take frequent breaks. If you?re beginning a new exercise program or a new sport, work up gradually to higher levels of fitness. And anytime you?re in pain, stop. Work on technique. Make sure your technique is correct if you play tennis, golf, or any sport that may strain your shoulder. Watch out for ?elbow-itis.? If you habitually lean on your elbow at your work desk, this may be a sign that your chair is uncomfortable or the wrong height. Try to arrange your work space so that you don?t have to lean on your elbow to read, write, or view your computer screen. Take knee precautions. If you have a task that calls for lots of kneeling (for example, refinishing or waxing a floor), cushion your knees, change position frequently, and take breaks. Wear the right shoes. High-heeled or ill-fitting shoes cause bunions, and tight shoes can also cause bursitis in the heel. Problems in the feet can also affect the hips. In particular, the tendons and bursae in the hips can be put under excessive strain by worn-down heels. Buy shoes that fit and keep them in good repair. Never wear a shoe that?s too short or narrow. Women should save their high heels for special occasions only. Avoid staying in only one position for too long. Get up and walk around for a while or change positions frequently.
