Bursa is a fluid filled sac of tissue that is often found around the bony prominences over which tendons and soft tissues rub. This therefore helps the tendons to glide with least amount of friction. Retrocalcaneal bursa is found behind the heel under the Achilles tendon. Retrotendoneal bursa is found on the back of the attachment of the tendon where the shoe rubs on the skin. This can cause swelling, pain and difficulty in footwear. Sometimes there is a bony prominence on the heel bone that predisposes to this condition (Haglund?s deformity). Treatment of this can be modification of footwear. However surgery is often required which involves excision of the bursa and also the bony prominence on the heel bone.
The retrocalcaneal bursa can become inflamed as the result of another condition, such as damage to the Achilles tendon, osteoarthritis, rheumatoid arthritis, gout, and pseudogout. In these instances, the treatment for bursitis must accompany treatment for the underlying condition. Septic retrocalcaneal bursitis, which is caused by an infection, is uncommon. Infection can reach the bursa through a cut, puncture, a blister, or even an insect bite. It is possible to have septic bursitis without an obvious opening. In these cases the superficial wound may have healed quickly, but still allowed bacteria into the bursa.
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.
A thorough subjective and objective examination from a physiotherapist may be all that is necessary to diagnose a retrocalcaneal bursitis. Diagnosis may be confirmed with an ultrasound investigation, MRI or CT scan.
Non Surgical Treatment
Non-operative treatment is the standard approach to treating posterior heel pain. It is highly desirable to treat this condition non-operatively, as operative treatment is often associated with a prolonged recovery. Traditional non-operative treatment includes the following. Heel Lift or the Use of a Shoe with a Moderate Heel. Walking barefoot or in a flat-soled shoe increases the tension on the insertion of the Achilles tendon. Using a heel lift or a shoe with a moderate heel can help reduce the stress on the tendon and decrease the irritation caused by this condition.
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.
