Haglund’s deformity is an enlargement of the bone on the back of the heel that can lead to inflammation, irritation, and pain. It is most common in young women, because it is often caused by the rigid backs of pump-style shoes.
Hereditary factors also play a part in the formation of Haglund’s deformity. High foot arch or a tendency to walk on the outside of the heel can contribute to Haglund’s. Non-surgical treatments are available, but surgery is sometimes necessary. One of several procedures may be used, depending on your particular foot and ankle structure.
