Haglund's syndrome
Haglund's syndrome is a group of signs and symptoms consisting of Haglund's deformity (which is an exostosis of the posterior calcaneal tuberosity) in combination with retrocalcaneal bursitis. It is often accompanied by Achilles tendinitis. Haglund's deformity typically presents with a prominent bump on the upper posterior calcaneus. Its causes are not fully understood. Treatment includes shoe adjustment, foot orthosis, physical therapy, medications, and in resistant cases surgical removal of the deformity.
