A bursa is a fluid-filled sac. There are hundreds of deep and superficial bursae throughout the human body. They are typically located near major joints. Bursae are situated between bone and soft tissues like tendons, ligaments, muscles, and skin. They serve as a cushioning pad to absorb shock. The fluid within the sac is secreted to assist with friction-free movement as the soft tissues move across a bony area.
Bursitis can develop for several reasons, including repetitively engaging in the same motion, or example, lifting objects above your head for work. Putting a lot of pressure on a bursa for an extended period of time. Leaning on your elbows or kneeling (for example, to lay carpet) can cause bursitis in the elbows or knees. If you sit for long periods of time, especially on hard surfaces, you may develop bursitis in your hip. Wearing shoes with a stiff back that rubs against the back of the ankle can cause Achilles tendon bursitis. Trauma. The bursae at the knee and elbow are close to the surface of the skin, and if you fall directly on your elbow or the knee, you can rupture, injure or puncture a bursa. Infection. Known as septic bursitis, it?s the result of bacteria infecting a bursa. It can occur from an infection traveling from another site or following an accident that ruptures the bursa. Even scraping the skin on your elbow or getting a mosquito bite that breaks the skin near the olecranon bursa (near the elbow) can lead to bursitis. Other joint disorders, such as rheumatoid arthritis, osteoarthritis and gout, or health conditions.
The signs and symptoms of heel bursitis can include heel pain wearing particular footwear, Pain or discomfort in the heel when walking, jogging or running, Swelling or inflammation in the heel.
During the physical examination of a patient with calcaneal bursitis, the physician should keep the following considerations in mind. Swelling and redness of the posterior heel (the pump bump) may be clearly apparent. The inflamed area, which may be slightly warm to the touch, is generally tender to palpation. Careful examination can help the clinician to distinguish whether the inflammation is posterior to the Achilles tendon (within the subcutaneous calcaneal bursa) or anterior to the tendon (within the subtendinous calcaneal bursa). Differentiating Achilles tendinitis/tendinosis from bursitis may be impossible. At times, the 2 conditions co-exist. Isolated subtendinous calcaneal bursitis is characterized by tenderness that is best isolated by palpating just anterior to the medial and lateral edges of the distal Achilles tendon. Conversely, insertional Achilles tendinitis is notable for tenderness that is located slightly more distally, where the Achilles tendon inserts on the posterior calcaneus. A patient with plantar fasciitis has tenderness along the posterior aspect of the sole, but he/she should not have tenderness with palpation of the posterior heel or ankle. A patient with a complete avulsion or rupture of the Achilles tendon demonstrates a palpable defect in the tendon, weakness in plantarflexion, and a positive Thompson test on physical examination. During the Thompson test, the examiner squeezes the calf. The test is negative if this maneuver results in passive plantarflexion of the ankle, which would indicate that the Achilles tendon is at least partially intact.
Non Surgical Treatment
According to the National Institutes of Health, custom heel wedges can be purchased by people suffering from retrocalcaneal bursitis. These wedges reduce stress on the heel, which can reduce the pain and inflammation associated with an inflamed bursa. They can be purchased without a prescription, making it easy for anyone experiencing a flare-up of symptoms to get the added support of these wedges.
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.
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.
