Overview
The foot only contains one naturally occurring bursal sac between the Achilles tendon and the heel bone, which protects the Achilles from the pressure against the heel bone during ambulation. However, shoes may put pressure on this bursa. The bursa might also incur trauma from walking on hard ground. And, though they are not naturally occurring, bursa sacs can also form, and become inflamed, in other parts of the foot, including the bottom of the heel, and the metatarsal plate, the outside of the foot below the fifth toe, and so on.
Causes
The most common causative organism is Staphylococcus aureus (80% of cases), followed by streptococci. However, many other organisms have been implicated in septic bursitis, including mycobacteria (both tuberculous and nontuberculous strains), fungi (Candida), and algae (Prototheca wickerhamii). Factors predisposing to infection include diabetes mellitus, steroid therapy, uremia, alcoholism, skin disease, and trauma. A history of noninfectious inflammation of the bursa also increases the risk of septic bursitis.
Symptoms
Symptoms of Achilles bursitis are often mistaken for Achilles tendinitis because of the location of the pain at the back of the heel. When you suffer from Achilles bursitis you will experience some or all of the following symptoms which are most noticeable when you begin activity after resting. High heels can add pressure on the retrocalcaneal bursa, subcutaneous calcaneal bursa, and Achilles tendon.
Diagnosis
Diagnosis of heel bursitis can be made by your health practitioner and is based on the following. Assessing the location of the pain by palpating the back of the heel. Assessment of any inflammation at the back of the heel. Assessment of biomechanics and foot function. Ultrasound or MRI can reveal inflammation of the retro calcaneal bursa.
Non Surgical Treatment
With anterior and posterior Achilles tendon bursitis, applying warm or cool compresses to the area and using nonsteroidal anti-inflammatory drugs (NSAIDs) can temporarily relieve the pain and inflammation, as can injections of a corticosteroid/anesthetic mixture into the inflamed bursa. The doctor is careful not to inject the mixture into the tendon. After this treatment, the person should rest. When these treatments are not effective, part of the heel bone may need to be surgically removed.
Surgical Treatment
Only if non-surgical attempts at treatment fail, will it make sense to consider surgery. Surgery for retrocalcanel bursitis can include many different procedures. Some of these include removal of the bursa, removing any excess bone at the back of the heel (calcaneal exostectomy), and occasionally detachment and re-attachment of the Achilles tendon. If the foot structure and shape of the heel bone is a primary cause of the bursitis, surgery to re-align the heel bone (calcaneal osteotomy) may be considered. Regardless of which exact surgery is planned, the goal is always to decrease pain and correct the deformity. The idea is to get you back to the activities that you really enjoy. Your foot and ankle surgeon will determine the exact surgical procedure that is most likely to correct the problem in your case. But if you have to have surgery, you can work together to develop a plan that will help assure success.
