Bursitis accounts for 0.4% of all visits to primary care clinics. The most common locations of bursitis are the subdeltoid, olecranon, ischial, trochanteric, and prepatellar bursae. The incidence of bursitis is higher in athletes, reaching levels as high as 10% in runners. Approximately 85% of cases of septic superficial bursitis occur in men. A French study aimed at assessing the prevalence of knee bursitis in the working population found that most cases occurred in male workers whose occupations involved heavy workloads and frequent kneeling. Mortality in patients with bursitis is very low. The prognosis is good, with the vast majority of patients receiving outpatient follow-up and treatment.
A bursa acts as a cushion and lubricant between tendons or muscles sliding over bone. There are bursas around most large joints in the body, including the ankle. The retrocalcaneal bursa is located in the back of the ankle by the heel. It is where the large Achilles tendon connects the calf muscles to the heel bone. Repeated or too much use of the ankle can cause this bursa to become irritated and inflamed. Possible causes are too much walking, running, or jumping. This condition is usually linked to Achilles tendinitis. Sometimes retrocalcaneal bursitis may be mistaken for Achilles tendinitis. Risks for this condition include starting an aggressive workout schedule, or suddenly increasing activity level without the right conditioning.
Your feet are extremely resilient and are designed to stand up to the pressures of day-to-day living. In some cases, though, foot structures may break down when subjected to chronic stress associated with prolonged periods of weight-bearing activity on concrete, asphalt, or other hard surfaces (especially when your footwear does not allow for appropriate weight distribution). Foot problems, including infracalcaneal bursitis, are often exacerbated by poorly designed footwear, and pressure, impact, and shear forces can damage your feet over time. Bursal sacs are intended to minimize this damage, but sometimes the bursa itself becomes inflamed.
Your GP or therapist will be able to diagnose you by both listening to your history and examining you. No X-rays or further investigation should be needed to confirm diagnosis but may be requested to check for any underlying health conditions that may have triggered the bursitis.
Non Surgical Treatment
Relieving the symptoms of bursitis initially focuses on taking the pressure off the bursa. This can be done with proper cushioning, inserts, or footwear but may require surgery if it is a bone formation problem (i.e. Huglund’s Deformity). If your bursitis is caused by an infection (septic bursitis), the doctor will probably drain the bursa sac with a needle and prescribe antibiotics to treat the infection.
Surgery is rarely need to treat most of these conditions. A patient with a soft tissue rheumatic syndrome may need surgery, however, if problems persist and other treatment methods do not help symptoms.
