Posterior achilles tendon bursitis

[Michiko]

Posterior Achilles tendon bursitis is inflammation of a bursa that forms in response to shoe pressure and is located at the top edge of the posterior shoe counter between the skin and Achilles tendon. Diagnosis is clinical. Treatment is footwear modification.

Posterior Achilles tendon bursitis occurs mainly in young women. Wearing high-heeled shoes is a risk factor. Another risk factor is a bony prominence (Haglund deformity) on the calcaneus. This deformity predisposes to bursa formation if repeatedly irritated by the shoe counter.
