Haglund’s deformity is a bony enlargement on the back of the heel that most often leads to painful bursitis, which is an inflammation of the bursa (a fluid-filled sac between the tendon and bone). In Haglund’s deformity, the soft tissue near the Achilles tendon becomes irritated when the bony enlargement rubs against shoes.

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, the deformity is most common in young women who wear pumps.

Symptoms

Haglund’s deformity can occur in one or both feet. The signs and symptoms include:

  • A noticeable bump on the back of 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.

What Causes Haglund’s Deformity?

To some extent, heredity plays a role in Haglund’s deformity. People can inherit a type of foot structure that makes them prone to developing this condition. For example, high arches can contribute to Haglund’s deformity. The Achilles tendon attaches to the back of the heel bone, and in a person with high arches, the heel bone is tilted backward into the Achilles tendon.

This causes the uppermost portion of the back of the heel bone to rub against the tendon. Eventually, due to this constant irritation, a bony protrusiHaglund Deformity | Albuquerque Expert Podiatriston develops and the bursa becomes inflamed. It is the inflamed bursa that produces the redness and swelling associated with Haglund’s deformity. A tight Achilles tendon can also play a role in Haglund’s deformity, causing pain by compressing the tender and inflamed bursa.

In contrast, a tendon that is more flexible results in less pressure against the painful bursa. Another possible contributor to Haglund’s deformity is a tendency to walk on the outside of the heel. This tendency, which produces wear on the outer edge of the sole of the shoe, causes the heel to rotate inward, resulting in a grinding of the heel bone against the tendon. The tendon protects itself by forming a bursa, which eventually becomes inflamed and tender.

Diagnosis

After evaluating the patient’s symptoms, the foot and ankle surgeon will examine the foot. In addition, x-rays will be ordered to help the surgeon evaluate the structure of the heel bone.

Treatment: Non-surgical Approaches to Haglund’s Deformity

Non-surgical treatment of Haglund’s deformity is aimed at reducing the inflammation of the bursa. While these approaches can resolve the bursitis, they will not shrink the boney protrusion.

When is Surgery Needed?

If non-surgical treatment fails to provide adequate pain relief, surgery may be needed. The foot and ankle surgeon will determine the procedure that is best suited to your case. It is important to follow the surgeon’s instructions for post-surgical care.

Prevention of Haglund’s Deformity

A recurrence of Haglund’s deformity may be prevented by:

  • Wearing appropriate shoes; avoid pumps and high-heeled shoes.
  • Using arch supports or orthotic devices.
  • Performing stretching exercises to prevent the Achilles tendon from tightening.
  • Avoiding running on hard surfaces and running uphill.
