Between the heel bone and the plantar fascia is a small fluid filled sac that is called the plantar (bottom of) calcaneal (heel bone) bursa. The plantar calcaneal bursa?s job is to allow the plantar fascia to glide easily over the heel bone without irritation. If this becomes inflamed and irritated a plantar calcaneal bursitis occurs which can be extremely painful and disabling forcing the athlete to stop training.
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 long periods of weight-bearing activity on concrete, asphalt, or other hard surfaces (especially when footwear does not allow for proper weight distribution). Foot problems, including infracalcaneal bursitis, are often made worse by poorly designed footwear, and pressure, impact, and shear forces can damage the feet over time. Bursal sacs are intended to minimize this damage, but sometimes the bursa itself becomes inflamed. 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. Arthritic conditions. Acute or chronic infection. The following factors may increase a person?s risk of bursitis, including infracalcaneal bursitis. Poor conditioning. Exposure to cold weather. Participating in contact sports. Having a previous history of bursitis in any joint. Heel striking when running, especially in conventional running shoes with heel elevation.
Some of the symptoms of bursitis in the heel, or retrocalcaneal bursitis, are as described below. Severe pain in the heel area of the foot, sometimes radiating to the ankle, associated with physical activities like walking, jogging and even on physical contact to the area. The physical signs of heel bursitis, which are noticeable in the heel area, are reddish discoloration of the skin that is warm to touch.
In addition to a complete medical history and physical examination, diagnostic procedures for bursitis may include the following. X-ray. A diagnostic test that uses invisible electromagnetic energy beams to produce images of internal tissues, bones, and organs onto film. Magnetic resonance imaging (MRI). A diagnostic procedure that uses a combination of large magnets, radiofrequencies, and a computer to produce detailed images of organs and structures within the body. Ultrasound. A diagnostic technique that uses high-frequency sound waves to create an image of the internal organs. Aspiration. A procedure that involves removal of fluid from the swollen bursa to exclude infection or gout as causes of bursitis. Blood tests. Lab tests that are done to confirm or eliminate other conditions.
Non Surgical Treatment
Gradually progressive stretching of the Achilles tendon may help to relieve impingement on the subtendinous calcaneal bursa. Stretching of the Achilles tendon can be performed by having the patient place the affected foot flat on the floor and lean forward toward the wall until a gentle stretch is felt in the ipsilateral Achilles tendon. The stretch is maintained for 20-60 seconds and then is relaxed. Achilles stretch 1. The patient stands with the affected foot flat on the floor and leans forward toward the wall until a gentle stretch is felt in the ipsilateral Achilles tendon. The stretch is maintained for 20-60 seconds and then is relaxed. Achilles stretch 2. This stretch, which is somewhat more advanced than that shown in Images 1-2, isolates the Achilles tendon. It is held for at least 20-30 seconds and then is relaxed. To maximize the benefit of the stretching program, the patient should repeat the exercise for multiple stretches per set, multiple times per day. Ballistic (ie, abrupt, jerking) stretches should be avoided in order to prevent clinical exacerbation. The patient should be instructed to ice the posterior heel and ankle in order to reduce inflammation and pain. Icing can be performed for 15-20 minutes at a time, several times a day, during the acute period, which may last for several days. Some clinicians also advocate the use of contrast baths, ultrasound or phonophoresis, iontophoresis, or electrical stimulation for treatment of calcaneal bursitis. If the patient's activity level needs to be decreased as a result of this condition, alternative means of maintaining strength and cardiovascular fitness (eg, swimming, water aerobics) should be suggested.
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.
