Overview
Retrocalcaneal bursitis is a condition characterized by tissue damage and inflammation of the retrocalcaneal bursa (a small fluid filled sac located at the back of the heel) causing pain in the heel region. A bursa is a thin fluid filled sac found in various places throughout the body. Bursae are designed to reduce friction between adjacent layers of tissue and are filled with lubricating fluid. They are typically located in regions of the body where tissue layers may rub against each other or against bony prominences The muscle group at the back of the lower leg is commonly called the calf. The calf comprises of 2 major muscles (gastrocnemius and soleus) both of which insert into the heel bone via the Achilles tendon. Between the Achilles tendon and the heel bone lies a bursa known as the retrocalcaneal bursa.
Causes
Overtraining in a runner (eg, excessive increases in miles or intensity). Tight or poorly fitting shoes that, because of a restrictive heel counter, exert excessive pressure on the posterior heel and ankle
Haglund deformity, causing impingement between the increased posterior superior calcaneal prominence and the Achilles tendon during dorsiflexion. More recent research suggests that a misaligned subtalar joint axis (measured in terms of joint inclination and deviation) in relation to the Achilles tendon can result in an asymmetrical force load on the tendon, disrupting normal biomechanics. This altered joint axis is associated with an increased risk for Achilles pathologies, including bursitis.
Symptoms
Patients with this condition typically experience pain at the back of the ankle and heel where the Achilles tendon attaches into the heel bone. Pain is typically experienced during activities requiring strong or repetitive calf contractions (often involving end of range ankle movements) such as walking (especially uphill), going up and down stairs, running, jumping or hopping (especially whilst wearing excessively tight shoes). Often pain may be worse with rest after these activities (especially that night or the following morning). The pain associated with this condition may ‘warm up’ with activity in the initial stages of injury. As the condition progresses, patients may experience symptoms that increase during sport or activity, affecting performance. In severe cases, patients may walk with a limp or be unable to weight bear on the affected leg. Other symptoms may include tenderness on firmly touching the affected bursa and swelling around the Achilles region.
Diagnosis
Bursitis is usually diagnosed after a careful physical examination and a full review of your medical history. If you garden and spend a lot of time on your knees, or if you have rheumatoid arthritis, tell your doctor, this information can be very helpful. During the physical exam, he or she will press on different spots around the joint that hurts. The goal is to locate the specific bursa that is causing the problem. The doctor will also test your range of motion in the affected joint. Other tests usually aren?t required to diagnose bursitis, but your doctor may suggest an MRI, X-ray or ultrasound to rule out other potential causes of pain.
Non Surgical Treatment
Treatment for soft tissue conditions focuses on reducing pain and inflammation, and on preserving mobility and preventing disability and recurrence. The treatment for many soft tissue conditions is similar. A doctor’s recommendations may include a combination of rest, splints, heat and cold application, medications, physical therapy, or occupational therapy. A person with a soft tissue condition may try several treatments before he or she finds the best one for his or her specific condition.
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.
