Bursitis Of The Foot Anatomy

Overview

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.

Causes

Occasionally the bursal sac can become inflamed and painful. Pain to the region is worse typically with initial weight bearing activity such as rising from bed in the morning. Swelling and warmth to the region are common. Clinical examination shows pain to palpation at the retrocalcaneus at a level just before the Achilles tendon. Increase pressure and friction of the Achilles tendon across the retrocalcaneal region is the cause of this bursitis. A high arch, tight Achilles tendon or bone spur appear to be some of the main causes of this problem. With a high arch the back portion of the calcaneus abnormally projects into the Achilles tendon region.

Symptoms

Bursitis involving the heel causes pain in the middle of the undersurface of the heel that worsens with prolonged standing and pain at the back of the heel that worsens if you bend your foot up or down.

Diagnosis

Gram stain. A lab test called a Gram stain is used to determine if certain troublesome bacteria are present. Not all bacteria can be identified with a Gram stain, however, so even if the test comes back negative, septic bursitis cannot be completely ruled out. White blood cell count. An elevated number of white blood cells in the bursa's synovial fluid indicates an infection. Glucose levels test. Glucose levels that are significantly lower than normal may indicate infection.

Non Surgical Treatment

In addition to being aware of foot-wear and inserts, be sure to modify your activity level to reduce the pain initially. Taking non-steroidal anti-inflammatory drugs (NSAIDs) and icing twice a day for 20 minute periods can help reduce the swell that leads to heel pain. Cortisone injections (more powerful anti-inflammatory medications) can be considered if your symptoms are persistent. After the swelling and pain has receded, ask your podiatrist about working with a physical therapist to strengthen the affected area in order to avoid bursitis by using your muscles in a more safe and efficient manner. If all these treatment methods fail, surgery may be the best option to excise a painful bursa (note that this is in rare cases).

Surgical Treatment

Surgery is rarely done strictly for treatment of a bursitis. If any underlying cause is the reason, this may be addressed surgically. During surgery for other conditions, a bursa may be seen and removed surgically.

Prevention

You can avoid the situation all together if you stop activity as soon as you see, and feel, the signs. Many runners attempt to push through pain, but ignoring symptoms only leads to more problems. It?s better to take some time off right away than to end up taking far more time off later. Runners aren?t the only ones at risk. The condition can happen to any type of athlete of any age. For all you women out there who love to wear high-heels-you?re at a greater risk as well. Plus, anyone whose shoes are too tight can end up with calcaneal bursitis, so make sure your footwear fits. If the outside of your heel and ankle hurts, calcaneal bursitis could be to blame. Get it checked out.
