Infracalcaneal bursitis (inflammation of the bursa below the calcaneus, or heel bone) is one of the most common types of bursitis in the foot. 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.
If the posterior-superior portion of the heel has an abnormally large bony prominence protruding from it (called a Haglund's Deformity), in some instances it may rub against the Achilles Tendon. When this occurs, the bursa between the bone and the tendon will become inflamed, swollen, and painful. This condition is called Retrocalcaneal Bursitis. The presence of a Haglund's Deformity does not insure that these problems will occur. In order for these problems to occur, the heel and foot must be tilted in such a way as to actually force this bony prominence into the bursa and tendon.
Pain at the back of the heel at the attachment site of the Achilles tendon when running. Pain on palpation of the back of the heel or bottom of heel. Pain when standing on tiptoes. Swelling and redness at the back and bottom of the heel.
Your doctor will check for bursitis by asking questions about your past health and recent activities and by examining the area. If your symptoms are severe or get worse even after treatment, you may need other tests. Your doctor may drain fluid from the bursa through a needle (aspiration) and test it for infection. Or you may need X-rays, an MRI, or an ultrasound.
Non Surgical Treatment
Over-the-counter or custom heel wedges may help to decrease the stress placed on the attachment of the achilles tendon and the associated bursa. If these interventions are ineffective, then some health care providers may inject a small amount of steroids into the bursa. If the condition is associated with Achilles tendonitis, then casting the ankle to prevent motion for several weeks can be effective. Very rarely, surgery may be necessary to remove the inflamed bursa.
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.
