Haglund’s deformity is a painful bump on the back of the heel. This has been referred to as a “pump bump”, as high heel shoes irritate this bump causing much pain. This may also medically be referred to as a retrocalcaneal exostosis. Retro means behind and calcaneal refers to the bone it involves, the calcaneous (heel bone).
What are the causes of Haglund’s Deformity?
Haglund’s deformity is often called “pump bump” because the rigid backs of pump-style shoes can create pressure that aggravates the enlargement when walking. In fact, any shoes with a rigid back, such as ice skates, men’s dress shoes, or women’s pumps, can cause this irritation.
To some extent, heredity plays a role in Haglund’s deformity. Inherited foot structures that can make one prone to developing this condition include:
- A high-arched foot
- A tight Achilles tendon
- A tendency to walk on the outside of the heel.
Symptoms of Haglund’s Deformity
Haglund’s deformity can occur in one or both feet. The symptoms include:
- A noticeable bump on the back of the heel
- Pain in the area where the Achilles tendon attaches to the heel
- Swelling in the back of the heel
- Redness near the inflamed tissue
