Retrocalcaneal Bursitis is an inflammation of the protective sack between the heel bone and the Achilles tendon. It is the inflamed bursa that produces the redness and swelling associated with Haglund’s deformity.
Repetitive, vigorous movement, strenuous and unaccustomed activities that put pressure on a joint, or a blow or other injury can bring on bursitis. The cause can vary depending on where the bursitis occurs. In the shoulder, for example, it can be brought on by excessive strain, such as from serving in tennis. Kneeling on a hard floor can cause bursitis of the knee, and similarly, repeatedly resting the elbow on a hard surface (such as a desk) can cause bursitis in that joint. Arthritis, gout, and certain infections can also contribute to the problem. Bursitis, in fact, may signal the onset of arthritis. While getting older isn’t a cause of bursitis, older people, especially older athletes, are more likely to develop the condition.
A dull ache under the heel when not weight bearing. Sometimes severe pain when walking. Pain can increase after resting (sleeping or sitting) then standing and placing pressure on the area again. Throbbing under the heel. Swelling may be identified as a discernible lump under the heel. This is the swollen calcaneal bursa itself. Tingling under the heel as swelling affect the plantar nerves. Pains shooting into the foot or up the leg.
Careful examination by your physician or physiotherapist can determine if the inflammation is from the Achilles tendon or from the retrocalcaneal bursa. Tenderness due to insertional Achilles tendinitis is normally located slightly more distal where the tendon inserts into the back of the heel, whereas tenderness caused by the retrocalcaneal bursa is normally palpable at the sides of the distal Achilles tendon. Diagnosis can be confirmed with an ultrasound investigation, MRI or CT scan.
Non Surgical Treatment
Treatment is primarily comprised of relief from the painful activity (running). It is important that shoes do not pinch the heel. If satisfactory progress is not made during the rehabilitation, medical treatment can be considered in the form of rheumatic medicine (NSAID) or injection of corticosteroid in the bursa. Injections should be performed under ultrasound guidance to ensure optimal effect and reduce the risk of injecting into the Achilles itself. If progress is not made neither through rehabilitation nor medicinal treatment, surgical treatment can be attempted.
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.
