Haglund’s deformity is a bony protrusion at the back of the heel that becomes inflamed. This condition can affect one or both feet and is often called the “pump bump” because it typically affects young women who wear high-heeled shoes.

Causes of Haglund’s Deformity

The most common cause of Haglund’s deformity is wearing high-arched shoes that cause the heel to tilt backward toward the tendon. Shoes with high arches and firm backs put pressure on the back of the heel, irritating the area around the enlarged bone. This pressure leads to inflammation of the soft tissue that cushions the bone and Achilles tendon.

Heredity may also play a role in Haglund’s deformity, as foot structure can increase susceptibility. Additionally, placing more weight on the outside of the heels while walking can cause the bone and tendon to rub together, increasing the likelihood of developing the condition. Tight and inflexible Achilles tendons can also worsen the deformity by compressing the already inflamed tissues.

Symptoms of Haglund’s Deformity

Symptoms include:

  • A large bump on the back of the heel
  • Pain near the Achilles tendon
  • Redness around the affected area
  • Swelling of the soft tissues at the back of the heel

Treatment of Haglund’s Deformity

Treatment options for Haglund’s deformity vary based on the severity of the condition. Non-surgical treatments aim to reduce inflammation and pain but will not reduce the bony protrusion.

Non-surgical treatments:

  • Applying ice or cold compresses to the affected area for 20 minutes at a time throughout the day to reduce swelling
  • Using ultrasound therapy to reduce inflammation
  • Taking anti-inflammatory medications to alleviate pain and swelling
  • Applying topical pain medications
  • Wearing a cast or boot to immobilize the foot, allowing the tendon and surrounding tissues to heal (typically for more severe cases)

Preventive steps:

To prevent the condition from worsening, consider:

  • Adding heel lifts to shoes with high arches to reduce pressure on the heel
  • Stretching to increase Achilles tendon flexibility
  • Using arch supports to control foot motion
  • Wearing backless shoes or shoes with soft backs to reduce pressure
  • Using heel pads to minimize irritation

If non-surgical treatments don’t provide sufficient relief, surgery may be necessary. Consult your doctor to discuss surgical options and determine the best approach for your needs.
