Haglund’s Deformity 2026: Heel Bump Causes & Treatment

The bump on the back of your heel that rubs against every shoe you own — that’s Haglund’s deformity, and it is one of the most commonly misidentified sources of posterior heel pain. Patients come in having been treated for Achilles tendinitis for months, when the real driver is the sharp bony ridge at the heel’s upper edge causing mechanical impingement with every step. Getting the diagnosis right changes everything about the treatment.

What Is Haglund’s Deformity?

Haglund’s deformity is a bony overgrowth on the posterosuperior aspect of the calcaneus — the upper back corner of the heel bone. As this prominence develops, it creates mechanical impingement against two structures that share that space: the Achilles tendon (which inserts onto the heel bone just below this area) and the retrocalcaneal bursa (a fluid-filled sac between the Achilles and the bone that cushions normal tendon movement). Repeated friction inflames both structures, producing a painful, swollen posterior heel that is exquisitely sensitive to shoe pressure.

The condition is sometimes called a “pump bump” because rigid-backed dress shoes and high heels — which press directly against the posterior heel counter — are the most common footwear aggravators. However, we see it in runners, men in hard-soled dress shoes, and patients with high arches whose heel bone sits in a more vertical orientation, placing extra force on the posterior prominence.

Symptoms

Haglund’s deformity produces a specific and recognizable symptom cluster that distinguishes it from mid-portion Achilles tendinopathy and plantar fasciitis.

• Visible or palpable bony bump on the upper back of the heel — often with overlying redness or callus
• Pain at the posterior heel where the Achilles inserts — not in the tendon body above, but at the very bottom of the tendon’s attachment
• Swelling and warmth posterior to the heel — retrocalcaneal bursitis
• Pain dramatically worsened by shoe heel counters — any closed-back shoe pressing on the bump
• Stiffness in the morning — improves after warming up but returns with prolonged activity
• Pain climbing stairs or hills — activities that require deep ankle dorsiflexion and compress the bursa

Haglund’s vs. Other Posterior Heel Pain — Key Differences	Haglund’s Deformity	Insertional Achilles Tendinopathy	Retrocalcaneal Bursitis
Location of Pain	Posterosuperior calcaneus; bony prominence	Posterior heel at Achilles insertion; may have calcification	Posterior heel; between Achilles and calcaneus (deeper)
X-Ray Finding	Enlarged posterior superior calcaneal bony prominence	May show calcification in tendon at insertion	No specific bony finding; soft tissue swelling
Palpation	Hard bony bump; firm	Tender at Achilles insertion; thickened tendon	Soft, fluctuant swelling between Achilles and heel bone
Best Initial Treatment	Heel lift + open-back shoe	Heel lift + flat-surface eccentric exercises	Heel lift + open-back shoe; ice and anti-inflammatories
All Three Can Coexist?	Yes — Haglund’s deformity causes retrocalcaneal bursitis AND secondary insertional Achilles tendinopathy from mechanical irritation. Treatment must address all three components.

Causes and Risk Factors

The bony prominence itself is largely determined by genetics — people with a high arch (cavus foot) have a heel bone that sits in a more vertical orientation, which rotates the posterosuperior aspect directly into the path of the Achilles tendon. Tight Achilles tendons also increase force on the insertion and compress the bursa. Contributing factors include: rigid shoe heel counters, high heels worn chronically then switched to flat shoes (sudden change in tendon loading), and leg length discrepancy. We see this condition in both athletes and non-athletes; the common thread is posterior heel compression or insertional Achilles overload.

How We Diagnose It

We start by pressing on exactly where it hurts: the bony corner of the heel, the bursa just in front of the Achilles, or the tendon’s attachment itself. That tells us which of the three overlapping problems is driving the pain. We check calf flexibility and arch height, then usually take a weight-bearing X-ray to see how prominent the heel bone is and whether there is calcification in the tendon. If the bursa or tendon looks heavily involved, an ultrasound or MRI shows the soft tissue. The plan almost always starts with conservative care.

Treatment Options

Treatment	Mechanism	When to Use	Expected Benefit
Heel Lift Orthotic (5–10 mm)	Reduces calcaneal inclination angle; decreases Achilles compression against Haglund’s prominence	First-line; all stages	Immediate pain reduction; 60–70% respond in 4–6 weeks
Open-Back or Soft-Counter Shoe	Eliminates friction of shoe heel counter against bony prominence	During acute flare; ongoing modification	Immediate relief of friction-related pain
Extracorporeal Shockwave Therapy (ESWT)	Stimulates tendon healing; reduces calcification; promotes vascularization	After 3–4 months conservative failure	60–70% good-to-excellent outcomes; avoids surgery
Physical Therapy (Achilles Eccentric Loading)	Strengthens Achilles; addresses insertional tendinopathy component; flat surface only	Mild-to-moderate; once acute inflammation controlled	Improved Achilles function; reduces tendinopathy component
Haglund’s Exostectomy (Endoscopic)	Removes posterior superior calcaneal prominence; ± retrocalcaneal bursectomy	Failed 6+ months conservative care	85–92% satisfactory outcomes; full recovery 3–6 months
Calcaneal Osteotomy (Zadek Osteotomy)	Rotates calcaneus to reduce prominence AND decompress Achilles insertion	Severe Haglund’s with insertional tendinopathy	Superior to simple exostectomy for complex cases; recovery 4–6 months

Conservative First-Line

• Open-back or soft-backed shoes — the single most important immediate intervention; removing all heel counter pressure eliminates the main mechanical irritant
• Heel lifts (1/4″ to 1/2″) — raise the heel to reduce the angle of Achilles compression against the posterior prominence
• Physical therapy — Achilles and gastrocnemius stretching (in pain-free range for insertional cases), eccentric heel drop exercises modified to avoid deep dorsiflexion, and posterior tibial tendon work
• Ice and NSAIDs — reduce bursitis inflammation during flares
• No cortisone injections — we don’t inject steroids at the back of the heel, even into the bursa: so close to the Achilles, a steroid shot can weaken the tendon and raise the risk of rupture
• Custom orthotics — particularly for high-arched patients; a posting correction can reduce the vertical heel orientation that drives impingement

Surgical Treatment

When 3–6 months of conservative care fails to provide adequate relief, surgical removal of the bony prominence (Haglund’s resection) is highly effective. The procedure can be performed open or endoscopically; the endoscopic approach has emerged as the standard in most centers because it provides equivalent bone removal with faster recovery and lower wound complication rates. Concurrent debridement of the degenerative Achilles insertion and bursectomy is performed when needed. Return to athletic activity: approximately 3–4 months post-operatively.

Frequently Asked Questions

Can Haglund’s deformity go away without surgery?

The bony prominence itself will not resorb — once the bone has remodeled in that shape, it does not go away without surgery. However, symptoms can resolve completely with conservative care: by eliminating shoe friction, reducing Achilles tension, and controlling bursitis inflammation, many patients become pain-free despite the persistence of the bony bump. Conservative management provides lasting symptom control in approximately 60–70% of patients who follow it consistently.

What shoes are best for Haglund’s deformity?

Open-back sandals or clogs are ideal during the acute phase — they eliminate all heel counter contact. When closed-back shoes are needed, look for shoes with a soft, padded heel counter that flexes easily under finger pressure. Avoid: stiff leather dress shoes, heels over 1 inch, rigid athletic cleats, and any shoe where the top of the heel counter presses directly against the bump. Some patients do well with shoes that have a notched or scalloped heel counter designed for Achilles sensitivity. For specific shoe models, see best shoes for Haglund deformity on Podiatrist Tested, our sister review site.

Why does the back of my heel only hurt in certain shoes?

Because the pain comes from a stiff heel counter pressing on the bony bump. Dress shoes, pumps, boots and skates rub it; open-back or soft-back shoes don’t, which is why the same heel can feel fine in sandals and sore in dress shoes.

Is a Haglund’s deformity the same as a heel spur?

No. A Haglund’s deformity is a bony bump at the back of the heel, next to the Achilles tendon. A classic heel spur sits on the bottom of the heel and goes with plantar fasciitis. Different spot, different problem.

Can I stop it from getting worse?

The heel shape itself runs in families, but avoiding rigid-backed shoes, keeping the calf flexible and using a heel lift when needed keep pressure off the bump and break the cycle of irritation that makes it hurt.

The Bottom Line

Haglund’s deformity is a structural issue that causes a specific, treatable pain pattern. Most patients get substantial relief with the right footwear, heel lifts, and targeted physical therapy. When surgery is needed, endoscopic resection offers an excellent and durable outcome with faster recovery than traditional open techniques.
