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.
A rapid increase in physical activity levels or thinning of the heel?s protective fat pad are factors that may contribute to infracalcaneal bursitis. Other possible causes of infracalcaneal bursitis include blunt force trauma, acute or chronic infection, and arthritic conditions. The following factors may increase your risk of experiencing bursitis, including infracalcaneal bursitis. Participating in contact sports. Having a previous history of bursitis in any joint. Poor conditioning. Exposure to cold weather. Heel striking when running, especially in conventional running shoes with heel elevation.
Achiness or stiffness in the affected joint. Worse pain when you press on or move the joint. A joint that looks red and swollen (especially when the bursae in the knee or elbow are affected). A joint that feels warm to the touch, compared to the unaffected joint, which could be a sign that you have an infection in the bursa. A ?squishy? feeling when you touch the affected part. Symptoms that rapidly reappear after an injury or sharp blow to the affected area.
A good clinical practise includes evaluation of the tendon, bursa and calcaneum by, careful history, inspection of the region for bony prominence and local swelling as well as palpation of the area of maximal tenderness. Biomechanical abnormalities, joint stiffness and proximal soft tissue tightening can exacerbate an anatomical predisposition to retrocalcaneal bursitis, they warrant correction when present.
Non Surgical Treatment
Rest and apply cold therapy or ice. Ice should not be applied directly to the skin as it may cause ice burns but wrap in a wet tea towel. Commercially available hot and cold packs are often more convenience than using ice. Taping the bursa with a donut shaped pad to take some of the pressure from footwear may help. A doctor may prescribe anti-inflammatory medication e.g. ibuprofen to reduce the pain and inflammation. Applying electrotherapy such as ultrasound may reduce inflammation and swelling. A steroid injection followed by 48 hours rest may be given for persistent cases. If the bursitis is particularly bad and does not respond to conservative treatment then surgery is also an option.
Bursectomy is a surgical procedure used to remove an inflamed or infected bursa, which is a fluid-filled sac that reduces friction between tissues of the body. Because retrocalcaneal bursitis can cause chronic inflammation, pain and discomfort, bursectomy may be used as a treatment for the condition when it is persistent and cannot be relived with other treatments. During this procedure, a surgeon makes small incisions so that a camera may be inserted into the joint. This camera is called an arthroscope. Another small incision is made so that surgical instruments can be inserted to remove the inflamed bursa.
