What Is Haglund’s Deformity? Causes & Heel Pain Relief

Heel pain isn’t always caused by common conditions like Plantar Fasciitis. For many people, especially those who wear structured shoes or stay active, the discomfort at the back of the heel may actually be due to Haglund’s deformity. This condition develops gradually but can become increasingly painful if left unaddressed.

Understanding what Haglund’s deformity is, why it develops, and how to treat it can help you take the right steps toward long-term heel pain relief.

What Is Haglund’s Deformity?

Haglund’s deformity is a bony enlargement that forms on the back of the heel, right where the Achilles tendon attaches to the heel bone. Over time, this extra bone creates a prominent bump that can rub against footwear, leading to irritation, inflammation, and persistent discomfort.

Because of its association with certain types of shoes, it’s often referred to as a “pump bump.” In medical terms, you may also hear it called retrocalcaneal exostosis. Regardless of the name, the underlying issue remains the same: excess pressure and friction at the back of the heel.

This condition is particularly common among active individuals, runners, and people who frequently wear stiff-backed shoes such as dress shoes or boots.

Where Does Haglund’s Deformity Occur?

Haglund’s deformity develops at the posterior aspect of the heel, an area that plays a crucial role in movement and stability. This location makes it especially vulnerable to irritation because it sits directly beneath the Achilles tendon and near the retrocalcaneal bursa, a small, fluid-filled sac that helps reduce friction.

As the bony bump enlarges, it can begin to interfere with both of these structures. The result is not just localized pain, but also inflammation that can spread to surrounding tissues. Many patients notice that symptoms worsen when wearing closed-back shoes, as repeated rubbing increases pressure on the area.

While it often affects one foot more than the other, Haglund’s deformity can develop in both heels, particularly if the underlying causes, like foot structure or footwear, are present on both sides.

What Causes Haglund’s Deformity?

Foot Structure and Biomechanics

One of the primary contributors to Haglund’s deformity is your natural foot structure. People with high arches are more likely to develop this condition because their heel tilts in a way that increases pressure on the back portion of the heel bone.

Additionally, a tight Achilles tendon can pull excessively on the heel, increasing friction where the tendon attaches. Over time, this repeated stress can stimulate the formation of extra bone. Abnormal walking patterns or poor biomechanics can further aggravate the issue, accelerating irritation and inflammation.

Footwear Choices

Shoes are one of the most significant external factors in the development of Haglund’s deformity. Footwear with rigid backs or tight heel counters tends to press directly against the bony area, creating repeated friction.

Common examples include:

• Dress shoes
• Boots
• Ice skates
• Cleats

When this type of pressure occurs consistently, the body may respond by forming additional bone in an attempt to protect the area, ironically making the problem worse.

Repetitive Stress and Activity

Activities that place repeated strain on the heel can also contribute to Haglund’s deformity. Running, long-distance walking, and standing for extended periods all increase pressure on the Achilles tendon and heel bone.

Athletes, in particular, are at higher risk due to the constant demand placed on their lower extremities. Over time, this repetitive stress can lead to inflammation and structural changes in the heel.

Genetic Factors

In some cases, Haglund’s deformity is influenced by genetics. If you have inherited foot traits such as high arches or a prominent heel bone, you may be more prone to developing this condition. A family history of heel pain or similar foot issues can also increase your risk.

Symptoms of Haglund’s Deformity

The symptoms of Haglund’s deformity often start subtly and gradually worsen. Many patients initially notice mild irritation at the back of the heel, which can progress into more persistent discomfort.

Common symptoms include pain at the back of the heel, especially when walking or wearing shoes, along with visible swelling near the Achilles tendon. The skin in this area may become red and irritated due to constant rubbing, and a firm, noticeable bump often develops over time.

As the condition progresses, stiffness in the Achilles tendon may occur, particularly after periods of rest. Physical activity and certain types of footwear typically make the pain worse, which can begin to interfere with daily routines.

Haglund’s Deformity vs Other Heel Pain Conditions

Haglund’s Deformity vs Plantar Fasciitis

Although both conditions cause heel pain, they affect different areas of the foot. Haglund’s deformity causes discomfort at the back of the heel, while Plantar Fasciitis typically results in pain at the bottom of the heel, especially during the first steps in the morning.

Haglund’s Deformity vs Achilles Tendonitis

Another commonly confused condition is Achilles Tendonitis. While Haglund’s deformity involves a bony enlargement, Achilles tendonitis is a soft tissue condition characterized by inflammation of the tendon itself.

It’s important to note that these two conditions often occur together. The presence of a bony bump can irritate the tendon, increasing the likelihood of inflammation and pain.

How Is Haglund’s Deformity Diagnosed?

Diagnosing Haglund’s deformity typically begins with a thorough physical examination. A podiatrist will assess the shape of your heel, look for visible swelling or redness, and evaluate areas of tenderness.

In addition to the physical exam, your doctor may review your footwear habits and activity levels to identify contributing factors. Imaging studies, such as X-rays, are often used to confirm the presence of a bony enlargement and determine its severity.

Early diagnosis is key, as it allows for more effective treatment and helps prevent complications such as chronic pain or damage to the Achilles tendon.

Can Haglund’s Deformity Go Away on Its Own?

One of the most common questions patients ask is whether Haglund’s deformity can resolve without treatment. Unfortunately, the bony growth itself does not go away naturally.

While symptoms may temporarily improve, especially with rest or footwear changes, they often return if the underlying issue is not addressed. Without proper care, the condition can progressively worsen and lead to ongoing discomfort.

Treatment Options for Haglund’s Deformity

Conservative Treatment Options

In many cases, Haglund’s deformity can be managed effectively with conservative care. Treatment typically focuses on reducing pressure, minimizing inflammation, and improving foot mechanics.

This may include switching to shoes with softer or open backs to reduce friction, using heel lifts or padding to protect the area, and performing targeted stretching exercises to relieve tension in the Achilles tendon. Custom orthotics can also help correct biomechanical issues that contribute to the condition.

Anti-inflammatory treatments, such as ice therapy or medications, may be recommended to manage swelling and discomfort.

Advanced & Surgical Treatment (When Needed)

When conservative treatments are not enough to provide relief, more advanced options may be considered. These approaches are typically reserved for persistent or severe cases that significantly impact daily life.

Surgical treatment focuses on removing the bony prominence and relieving pressure on the surrounding tissues. The specific procedure will depend on the severity of the deformity and whether the Achilles tendon is involved.

When Should You See a Podiatrist for Haglund’s Deformity?

It’s important to seek professional care if your heel pain does not improve with simple changes like adjusting your footwear. Persistent pain, swelling, or redness at the back of the heel should not be ignored.

If discomfort begins to interfere with walking, exercise, or daily activities, or if symptoms continue to worsen over time, a podiatric evaluation can help identify the cause and guide appropriate treatment.
