In your calf at the back of the lower leg sit two major muscles (gastrocnemius and soleus), both held by the Achilles tendon (Equinus). Between the Achilles tendon and the heel bone is a bursa sac
called a retrocalcaneal bursa ('calcaneus' = 'heel bone' and 'retro' = 'behind'). During contraction of the calf muscles, the Achilles tendon rubs against the retrocalcaneal bursa, which can become
irritated as a result.
Pain at the posterior heel or ankle is most commonly caused by pathology at either the posterior calcaneus (at the calcaneal insertion site of the Achilles tendon) or at its associated bursae. Two
bursae are located just superior to the insertion of the Achilles (calcaneal) tendon. Anterior or deep to the tendon is the retrocalcaneal (subtendinous) bursa, which is located between the Achilles
tendon and the calcaneus. Posterior or superficial to the Achilles tendon is the subcutaneous calcaneal bursa, also called the Achilles bursa. This bursa is located between the skin and posterior
aspect of the distal Achilles tendon. Inflammation of either or both of these bursa can cause pain at the posterior heel and ankle region.
Nagging ache and swelling in or around a joint. Painful and restricted movement in the affected joint. Pain radiating into the neck or arms when bursitis strikes the shoulder (the most common site).
Fever, when associated with an infection.
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
Non Surgical Treatment
Treatment is primarily comprised of relief from the painful activity (running). It is important that shoes do not pinch the heel. If satisfactory progress is not made during the rehabilitation,
medical treatment can be considered in the form of rheumatic medicine (NSAID) or injection of corticosteroid in the bursa. Injections should be performed under ultrasound guidance to ensure optimal
effect and reduce the risk of injecting into the Achilles itself. If progress is not made neither through rehabilitation nor medicinal treatment, surgical treatment can be attempted.
Surgery is rarely need to treat most of these conditions. A patient with a soft tissue rheumatic syndrome may need surgery, however, if problems persist and other treatment methods do not help
People can lower the risk of bursitis by gradually strengthening and stretching the muscles around the joints and taking regular breaks from repetitive motion that might irritate bursae. Prolonged
time resting on the elbows or kneeling should be avoided, if it cannot be avoided, wearing cushioned elbow and knee pads can help protect the bursae. Comfortable, supportive, low-heeled shoes can
help prevent bursitis in the foot.
