Bursitis Of The Foot Anatomy
Overview
Heel bursitis is specifically the inflammation of the retrocalcaneal bursa, located at the back of the heel, under the Achilles tendon. There are a handful of factors that put you at risk for developing heel bursitis. Long distance runners are prone to heel bursitis, due to repeated stress and pounding upon the heel joint. Engaging in activities such as running, bicycling, walking, jumping, and stair climbing for extended periods of time can overwork the heel joints and start to irritate the bursae. Suddenly changing to a high-intensity workout regime puts a lot of stress on the heel, making it vulnerable to injury. Hard blows/bumps to the heel can immediately damage the bursae, leading to swelling and inflammation. Training at high intensities without stretching and warming up can also contribute to the development of heel bursitis. Even improper footwear can be a big factor. Some other conditions can put you at risk as well, such as: tarsal tunnel syndrome, rheumatoid arthritis, plantar fasciitis, muscle weakness, joint stiffness, and heel spurs. It is very important to get a professional diagnosis if you are having heel pain because heel bursitis is often confused for Achilles tendonitis, and the proper treatments are very different. The pain could also be plantar fasciitis or general heel pain syndrome.
Causes
Bursitis, tendinitis, and other soft tissue rheumatic syndromes typically result from one or more factors. These include: Play or work activities that cause overuse or injury to the joint areas Incorrect posture Stress on the soft tissues from an abnormal or poorly positioned joint or bone (such as leg length differences or arthritis in a joint) Other diseases or conditions (rheumatoid arthritis, gout, psoriasis, thyroid disease, or an unusual drug reaction) Infection.
Symptoms
Pain when activating the Achilles tendon (running and jumping) and when applying pressure at the point of attachment of the tendon on the heel bone. Contrary to the tenderness occurring with inflammation of the Achilles tendon, the tenderness is localised to the point of attachment to the heel bone.
Diagnosis
Your doctor will take a history to find out if you have the symptoms of retrocalcaneal bursitis. By examining your ankle, he or she can generally tell the location of the pain. The physician will look for tenderness and redness in the back of the heel. The pain may be worse when the doctor bends the ankle upward (dorsiflex), as this may tighten the achilles tendon over the inflamed bursa. Alternatively, the pain may be worse with toe rise, as this puts stress on the attachment of the achilles tendon to the heel bone. Imaging studies such as X-ray and MRI are not usually necessary at first. If initial treatment fails to improve the symptoms, these studies may be obtained. MRI may show inflammation.
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 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).
