Haglund’s deformity — a bony enlargement of the posterior-superior aspect of the heel bone (calcaneus) — is a commonly misdiagnosed cause of posterior heel pain. Named after Swedish orthopedic surgeon Patrick Haglund who first described it in 1928, the condition is sometimes called “pump bump” because of its association with rigid-back pump shoes that rub against the enlarged prominence.
What Is Haglund’s Deformity?
Haglund’s deformity is a bony prominence at the upper back portion of the calcaneus — the point where the Achilles tendon inserts. The prominence creates a vicious cycle: the bony bump irritates the overlying skin and the retrocalcaneal bursa (the fluid-filled sac between the Achilles tendon and the heel bone), causing bursitis; the inflamed bursa enlarges and creates more pressure against the posterior shoe counter; the irritated Achilles tendon at its insertion becomes inflamed and degenerative (insertional Achilles tendinopathy).
Who Gets Haglund’s Deformity?
Several foot types are predisposed: high-arched feet (cavus) and feet with a prominent “Fowler-Philip angle” on lateral X-ray. It is more common in women (from pump shoes), runners (from rigid heel counters in racing shoes), and patients with tight Achilles tendons. However, it can affect anyone with the predisposing bony anatomy.
Symptoms
The classic presentation is: a visible and palpable bony bump at the upper-back heel, pain and redness in the same area (aggravated by shoe heel counters pressing on the prominence), occasional bursitis (fluctuant soft swelling at the back of the heel), and insertional Achilles tendon pain with activity — particularly during the push-off phase of walking.
Conservative Treatment
- Footwear modification — open-back shoes or shoes with soft or absent heel counters eliminate the mechanical irritation that perpetuates symptoms; this is often the most immediately effective intervention
- Heel lifts — raising the heel shifts the Achilles insertion angle and reduces impingement of the prominence against the shoe; custom orthotics with heel lift incorporated are preferred
- Ice and anti-inflammatory medications — for acute bursitis flares
- Physical therapy — eccentric Achilles exercises, gastrocnemius stretching, and soft tissue mobilization; the exercise protocol must be modified for insertional tendinopathy (no drop below step level, unlike mid-portion tendinopathy)
- Cortisone injection — targeted injection of the retrocalcaneal bursa for acute bursitis; avoid direct Achilles tendon injection (tendon rupture risk)
Surgical Treatment
When conservative care fails after 3–6 months, surgical resection of the Haglund’s prominence (calcaneal exostectomy) is highly effective. The procedure involves removing the bony enlargement — endoscopically or via a small open incision — allowing the retrocalcaneal bursa to decompress. When concurrent insertional Achilles tendinopathy is present, the degenerate tendon tissue is debrided and the tendon is reattached if detachment was required for adequate decompression. Recovery involves 6–8 weeks in a boot followed by gradual return to full activity over 3–6 months.

Differential Diagnosis: What Else Could It Be?
Not every case of haglund’s deformity is straightforward. In our clinic we routinely rule out three look-alike conditions before confirming the diagnosis. If your symptoms don’t match the classic presentation, one of these may explain the pain — which is why physical exam matters more than self-diagnosis.
| Condition | How It Differs |
|---|---|
| Retrocalcaneal bursitis alone | Anterior to the Achilles insertion, no posterior bone prominence. |
| Insertional Achilles tendinopathy | Pain at the tendon-bone junction; calcification may be present on X-ray. |
| Sever’s disease (pediatric) | Child or adolescent with growth-plate pain; Haglund presents in adults. |

In Our Clinic: What We See
Clinical perspective from Dr. Tom Biernacki, DPM — Balance Foot & Ankle, Howell & Bloomfield Hills, MI:
Haglund’s deformity — the ‘pump bump’ — is the posterior heel prominence that irritates every closed-back shoe the patient owns. In our clinic we address all three layers: the bone prominence (shoe modification, backless shoes), the retrocalcaneal bursa (ice and NSAIDs), and the often-inflamed Achilles insertion (eccentric heel drops, heel lifts). We rarely operate in the first 6 months — conservative care works in 70% of patients. When surgery is needed, we resect the prominence and address any calcified Achilles insertion. Dr. Biernacki always photographs patient shoes at the visit: fixing the shoe often fixes the Haglund.
