Infracalcaneal bursitis is inflammation of a bursa-a fluid-filled sac-below your calcaneus, or heel bone. Bursae are situated in various locations throughout your body where friction between tissues commonly occurs, and these sacs are designed to help reduce this friction and prevent pain. Repetitive movements or prolonged and excessive pressure are the most common causes of bursal inflammation, though traumatic injury may also cause this painful problem. Indeed, your body sometimes creates bursal sacs in response to trauma or tissue damage. Infracalcaneal bursitis can sometimes be difficult to differentiate from plantar fasciosis-another condition that causes pain below the heel. The key difference is that infracalcaneal bursitis tends to be worse at the end of the day whereas plantar fascia pain tends to be worse in the morning, immediately upon waking.
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.
Bursitis involving the heel causes pain in the middle of the undersurface of the heel that worsens with prolonged standing and pain at the back of the heel that worsens if you bend your foot up or down.
Medical examination is not necessarily required in light cases where the tenderness is minimal. In all cases where smooth improvement is not experienced, medical attention should be sought as soon as possible to exclude a (partial) rupture of the Achilles tendon or rupture of the soleus muscle. This situation is best determined by use of ultrasound scanning, as a number of injuries requiring treatment can easily be overlooked during a clinical examination (Ultrasonic image). Ultrasound scanning enables an evaluation of the extent of the change in the tendon, inflammation of the tendon (tendinitis), development of cicatricial tissue (tendinosis), calcification, inflammation of the tissue surrounding the tendon (peritendinitis), inflammation of the bursa (bursitis), as well as (partial) rupture.
Non Surgical Treatment
Surgery should always be the last option. We believe that biologic treatments that preserve normal anatomy are very helpful, particularly for runner, athletes, and active professionals with buy schedules. All non-surgical approaches attempt to calm down the inflammation of the bursa and Achilles tendon. They do not address the bony bump, but they can substantially reduce and shrink the inflamed soft tissue. Some non-surgical treatments include Oral Anti-inflammatory Medications. NSAID’s (non-steroidal anti-inflammatory medications) such as Motrin, Aleve, and Steroids (like prednisone) may help control the pain and stop the inflammation. Topical Anti-inflammatory Medications. NSAID’s in cream or lotion form may be applied directly to the inflamed area. With these, there is no concern for stomach upset or other problems associated with oral medication. Ice. Ice can applied be applied right to the red, inflamed area and help calm it down. Try applying a podiatrist-approved ice pack to the affected area for 20 minutes of each hour. Just make sure you don’t put ice directly against the skin. Exercises. Stretching exercises may relieve some of the tension in the Achilles tendon that started the problem. If you have Equinus Deformity (or a tight heel cord) this is critical to prevent it from coming back again. Heel lifts. Heel lifts placed inside the shoe can decrease the pressure on the Achilles tendon. Remember, pressure and friction cause the bump to become inflamed. Heel pads. Placing gel padding to cushion the Achilles tendon (at the back of the heel) can also help reduce irritation from shoes. Shoe modification. Wearing open-backed shoes, or shoes that have soft backs. This will also help stop the irritation. Physical therapy. Physical therapy, such as ultrasound, massage and stretching can all reduce the inflammation without surgery. Orthotic devices. Custom arch supports known as foot orthotics control abnormal motion in the foot that can allow the heel to tilt over and rub against the heel counter. Orthotics can decrease symptoms and help prevent it from happening again. Immobilization. In some cases, a walking cast boot or plaster/fiberglass cast is necessary to take pressure off the bursa and tendon, while allowing the area to calm down. ESWT. Extra-corporeal Shock Wave Therapy uses high energy sound waves to break up diseased tissue in the bursa and Achilles tendon and stimulate your own bodies healing processes to repair the diseased area. It may be done in the office or in a an outpatient surgery center. There is no incision and no stitches with ESWT. PRP. Platelet Rich Plasma (PRP) is a therapeutic injection. A small sample of blood is drawn from the patient and the healing factors found in the platelets are concentrated in a centrifuge. By injecting the concentrated solution right into the damaged Achilles tendon, a powerful healing can be stimulated. This can be done in the office. No hospital or surgery required.
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.
You can help to prevent heel pain and bursitis by maintaining a healthy weight, by warming up before participating in sports and by wearing shoes that support the arch of the foot and cushion the heel. If you are prone to plantar fasciitis, exercises that stretch the Achilles tendon (heel cord) and plantar fascia may help to prevent the area from being injured again. You also can massage the soles of your feet with ice after stressful athletic activities. Sometimes, the only interventions needed are a brief period of rest and new walking or running shoes.
