What Is Haglund Deformity?
Haglund deformity — commonly called a “pump bump” — is an enlargement of the posterosuperior prominence of the calcaneus (heel bone) that creates a bony bump at the back of the heel. This prominence impinges on the Achilles tendon insertion and the retrocalcaneal bursa — the fluid-filled cushion that lies between the tendon and the bone. The resulting pressure and friction cause a syndrome of posterior heel pain that includes bursitis, insertional Achilles tendinopathy, and pain with footwear.
The condition is named after Swedish surgeon Patrick Haglund, who described it in 1928. The “pump bump” colloquial name derives from the association with rigid-backed shoes — high heels, dress shoes, and ice skates — that create direct pressure over the bony prominence.
Who Gets Haglund Deformity?
Haglund deformity is most common in young to middle-aged women who regularly wear high heels or rigid-backed dress shoes, but it affects runners and other athletes as well. Anatomic risk factors include a high-arched (cavovarus) foot, a prominent calcaneal pitch angle, and tight Achilles tendon — all of which increase the impingement of the posterior calcaneal prominence on the retrocalcaneal bursa. A family history of heel bony prominence may contribute to predisposition.
Symptoms
The hallmark symptom is posterior heel pain — specifically at the back of the heel where the Achilles tendon meets the calcaneus. The pain is worsened by wearing shoes with rigid heel counters and often relieved when barefoot or in open-back sandals. Swelling and redness directly over the posterior heel are common, representing the inflamed retrocalcaneal bursa. On examination, a firm bony prominence is palpable at the posterosuperior calcaneus, often with an overlying soft tissue bursitis that feels like a fluid-filled cushion.
Diagnosis
X-ray confirms the bony enlargement and allows measurement of the calcaneal pitch angle and Fowler-Philip angle — radiographic parameters that quantify the degree of posterior heel prominence and guide surgical planning. MRI characterizes the extent of Achilles tendon involvement (insertional tendinopathy or partial tear), retrocalcaneal bursitis, and the soft tissue component of the deformity. This information is important both for confirming the diagnosis and for planning surgery if conservative treatment fails.
Conservative Treatment
Footwear Modification
The simplest and most effective first intervention is eliminating the footwear that creates posterior heel pressure. Open-back shoes, soft-backed athletic footwear, and footwear with a slightly elevated heel (one centimeter) all reduce direct impingement on the Haglund prominence. A heel lift inserted into shoes reduces the angle at which the Achilles tendon meets the calcaneus, decreasing retrocalcaneal bursa compression.
Physical Therapy
Eccentric calf strengthening and Achilles tendon stretching reduce the compressive load on the retrocalcaneal bursa and address associated insertional tendinopathy. Physical therapy is most effective when Achilles tendon pathology is a significant component of the syndrome alongside the bony deformity.
Corticosteroid Injection
Ultrasound-guided injection into the retrocalcaneal bursa reduces acute bursitis and pain. Injection directly into the Achilles tendon substance is avoided, as corticosteroids weaken tendon collagen and increase rupture risk. Bursal injection provides meaningful relief for many patients and may allow continued conservative management to succeed.
Surgical Treatment: Exostectomy
When conservative measures fail after three to six months, surgical removal of the Haglund prominence (calcaneal exostectomy) is performed. The posterosuperior calcaneal prominence is resected through a posterior or posterolateral incision, and any degenerated Achilles tendon insertion tissue is debrided. If the tendon insertion requires significant debridement, reattachment with suture anchors may be performed simultaneously. Endoscopic (minimally invasive) calcaneal exostectomy is available for appropriate candidates, reducing incision size and soft tissue trauma. Recovery involves a protective boot for four to six weeks followed by progressive rehabilitation. Return to regular footwear occurs at eight to twelve weeks.
Getting Evaluated for Posterior Heel Pain
Posterior heel pain has several potential causes — Haglund deformity, isolated insertional Achilles tendinopathy, and retrocalcaneal bursitis often coexist and require coordinated treatment. Contact Balance Foot & Ankle for comprehensive evaluation and an individualized treatment plan for your posterior heel pain.

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. |
Red Flags — When to See a Podiatrist Now
Seek same-day evaluation at Balance Foot & Ankle if you notice any of the following:
- Pain preventing use of regular closed-back shoes
- Open sore or breakdown over the posterior heel
- Failed 6+ weeks of shoe modification and stretching
- Associated insertional Achilles tendinopathy with calcification
Call (810) 206-1402 or request an appointment. Our Howell and Bloomfield Hills offices reserve same-day slots for urgent foot and ankle issues.
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.
