Bursitis Of The Foot Bursa Sac
Overview
Retrocalcaneal bursitis is a painful inflammation of the soft tissues at the attachment of the Achilles tendon to the back of the heel bone. The retrocalcaneus identifies the ?retro? or behind and ?calcaneus? or heel bone. Bursitis relates to inflammation of a bursa in the retrocalcaneal region. A bursa anatomically is a fluid filled sack that is located around tendinous attachments in the body. The retrocalcaneal bursa as identified in the photo 1 protects the Achilles tendon just prior to its insertion to the retrocalcaneal region. The retrocalcaneal bursa cushions the Achilles tendon and normally allows pain free motion of the Achilles tendon over the calcaneus.
Causes
Posterior heel pain can come from one of several causes. When a physician is talking about posterior heel pain, he or she is referring to pain behind the heel, not below it. Pain underneath the heel, on the bottom of the foot, has several causes including Tarsal Tunnel Syndrome. Plantar Fasciitis. Heel Spurs.
Symptoms
Symptoms of bursitis usually occur after rest and relaxation. Upon activity there is usually more intense pain in the area of the bursa. The common areas to have a bursitis in the foot are in the bottom of the heel, behind the heel near the attachment of the Achilles Tendon as well as along the side of a bunion. A bursa may also form in multiple areas especially along the metatarsal heads, or "ball" of your foot. You may actually feel the sac like fluid when rubbing the area of pain.
Diagnosis
Diagnosis is first by clinical suspicion of symptoms. This can be mistaken for gout or infection especially in the big toe region. A diagnosis of bursitis is usually used in combination of the underlying cause, for instance a bunion deformity, Haglund's deformity, or Heel Spur Syndrome. Many times the cause needs to be addressed to rid the problem of bursitis.
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.
Surgical Treatment
Surgery. Though rare, particularly challenging cases of retrocalcaneal bursitis might warrant a bursectomy, in which the troublesome bursa is removed from the back of the ankle. Surgery can be effective, but operating on this boney area can cause complications, such as trouble with skin healing at the incision site. In addition to removing the bursa, a doctor may use the surgery to treat another condition associated with the retrocalcaneal bursitis. For example, a surgeon may remove a sliver of bone from the back of the heel to alter foot mechanics and reduce future friction. Any bone spurs located where the Achilles attaches to the heel may also be removed. Regardless of the conservative treatment that is provided, it is important to wait until all pain and swelling around the back of the heel is gone before resuming activities. This may take several weeks. Once symptoms are gone, a patient may make a gradual return to his or her activity level before their bursitis symptoms began. Returning to activities that cause friction or stress on the bursa before it is healed will likely cause bursitis symptoms to flare up again.
