There are two main bursae involved in heel bursitis, the subtendinous calcaneal bursa and the subcutaneous calcaneal bursa. Both of these bursa are located near the Achilles tendon. The subtendinous calcaneal bursa, which is also referred to as the retrocalcaneal bursa, is on the back of the heel and is deeply situated between the Achilles tendon and the calcaneus. The subcutaneous calcaneal bursa, which is commonly referred to as the Achilles bursa, is located near the bottom of the heel between the skin and the distal aspect of the Achilles tendon. It?s much more superficial to the Achilles tendon than the subtendinous calcaneal bursa.
Wearing poorly fitting or constrictive footwear can cause the heel to become irritated and inflamed. Shoes that dig into the back of the heel are the primary cause of retroachilles bursitis. Foot or ankle deformity. A foot or ankle deformity can make it more likely to develop retrocalcaneal bursitis. For example, some people can have an abnormal, prominent shape of the top of their heel, known as a Haglund's deformity. This condition increases the chances of irritating the bursa. A trauma to the affected heel, such as inadvertently striking the back of the heel against a hard object, can cause the bursa to fill with fluid, which in turn can irritate and inflame the bursa's synovial membrane. Even though the body usually reabsorbs the fluid, the membrane may stay inflamed, causing bursitis symptoms.
Retrocalcaneal bursitis is very similar to Achilles bursitis as the bursae are very close in proximity and symptoms are almost identical however retrocalcaneal bursitis is a lot more common. The symptoms of bursitis vary depending on whether the bursitis is the result of injury or an underlying health condition or from infection. From normal overuse and injury the pain is normally a constant dull ache or burning pain at the back of the heel that is aggravated by any touch, pressure like tight shoes or movement of the joint. There will normally be notable swelling around the back of the heel. In other cases where the bursa lies deep under the skin in the hip or shoulder, swelling might not be visible. Movement of the ankle and foot will be stiff, especially in the mornings and after any activity involving the elbow. All of these symptoms are experienced with septic bursitis with the addition of a high temperature of 38?C or over and feverish chills. The skin around the affected joint will also appear to be red and will feel incredibly warm to the touch. In cases of septic bursitis it is important that you seek medical attention. With injury induced bursitis if symptoms are still persisting after 2 weeks then report to your GP.
Medical examination is not necessarily required in light cases where the tenderness is minimal. In all cases where smooth improvement is not experienced, medical attention should be sought as soon as possible to exclude a (partial) rupture of the Achilles tendon or rupture of the soleus muscle. This situation is best determined by use of ultrasound scanning, as a number of injuries requiring treatment can easily be overlooked during a clinical examination (Ultrasonic image). Ultrasound scanning enables an evaluation of the extent of the change in the tendon, inflammation of the tendon (tendinitis), development of cicatricial tissue (tendinosis), calcification, inflammation of the tissue surrounding the tendon (peritendinitis), inflammation of the bursa (bursitis), as well as (partial) rupture.
Non Surgical Treatment
You should rest from all activities that cause pain or limping. Use crutches/cane until you can walk without pain or limping. Ice. Place a plastic bag with ice on the foot for 15-20 minutes, 3-5 times a day for the first 24-72 hours. Leave the ice off at least 1 1/2 hours between applications. Compression. Lightly wrap an elastic bandage from the toes to mid calf, using even pressure. Wear this until swelling decreases. Loosen the wrap if your toes start to turn blue or feel cold. Elevate. Make sure to elevate the ankle above heart level. To improve symptoms of plantar calcaneal bursitis after the acute phasetry the baked bean tin stretch, using a baked bean tin roll the foot backwards and forwards. 2 minutes in the morning before putting the foot to the floor. 5-10 minutes every evening. Contrast foot baths. 10 minutes warm water. 10 minutes cool water morning and evening (morning may be missed if time is restricted). Stretches. Start with 10 stretches per day, holding the stretch for 30 seconds, then relax and then repeat. Continue this stretch daily until you can no longer feel it pulling on the heel, then progress to stretch. Do 10 per day holding for 30 seconds per stretch. When you can no longer feel it pulling on the heel proceed to stretches. Do 10 per day holding for 30 seconds on every stretch.
Contact your physician if bursitis pain is disabling (when movement of the joint is largely or entirely restricted), if the pain doesn?t subside after a week of self-care, or if the joint is red and swollen. Also call your doctor if you develop a fever, which could signal infectious bursitis-a condition that especially can afflict the elbow. Except for the fever, symptoms resemble other forms of bursitis, but infectious bursitis requires immediate medical attention.
