Haglund's Deformity (Retrocalcaneal Bursitis)

This condition is a bony enlargement on the back of the heel that can aggravate the retrocalcaneal bursa, a fluid-filled sac located on the back of the heel between the Achilles tendon and the calcaneus. The bursa can become inflamed and swollen, a condition called bursitis. Haglund's deformity most commonly affects young women.
