Haglund’s deformity — often called “pump bump” — is a bony enlargement of the back of the heel that can cause chronic pain, bursitis, and insertional Achilles tendinopathy. At Balance Foot & Ankle, our Michigan podiatrists diagnose and treat Haglund’s deformity conservatively and surgically, with excellent outcomes for appropriately selected patients.

What Is Haglund’s Deformity?

Haglund’s deformity is an enlargement of the posterosuperior prominence of the calcaneus (heel bone) — the bony bump at the very back of the heel where the upper edge of the shoe makes contact. This prominence irritates the retrocalcaneal bursa (a fluid-filled sac between the Achilles tendon and the heel bone) and the Achilles tendon insertion itself. The combined effect is a painful triad of: bony prominence, retrocalcaneal bursitis, and insertional Achilles tendinopathy.

The “pump bump” name comes from its association with rigid-backed shoes — particularly women’s pumps — that press directly against the prominent heel bone. However, Haglund’s deformity also commonly affects runners, military personnel, and anyone with a high-arched, cavus foot type (which drives the heel into the back of the shoe during push-off).

Symptoms

Classic symptoms include pain, swelling, and redness at the back of the heel — particularly where the shoe collar contacts the heel. A hard, bony bump may be visible. The area is tender to palpation, and pain is aggravated by wearing closed-back shoes, running uphill, and stair climbing. Redness, warmth, and a squishy sensation indicate retrocalcaneal bursitis. Insertional Achilles tendinopathy causes morning stiffness and pain with push-off that is distinct from mid-tendon Achilles pain (which occurs 2–6 cm above the insertion).

Diagnosis

Weight-bearing lateral X-ray shows the posterior calcaneal prominence and any calcification within the Achilles tendon at its insertion. The “parallel pitch lines” method on X-ray measures the degree of prominence. MRI provides detailed assessment of the bursa, Achilles insertion, and any intra-tendinous degeneration or partial tears — important for surgical planning. Diagnostic ultrasound shows the bursa in real time and guides aspiration or injection.

Conservative Treatment

Initial conservative management focuses on reducing friction and inflammation:

• Footwear modification: Open-back shoes (clogs, sandals, slip-ons) eliminate heel counter pressure entirely — most effective conservative measure; closed-back shoes with soft, padded collars and adequate heel clearance reduce irritation
• Heel lifts: Raises the heel within the shoe, reducing the contact angle between the prominence and shoe counter; also reduces Achilles tendon tension at insertion
• Ice and NSAIDs: Reduce acute bursitis and tendon inflammation
• Physical therapy: Calf flexibility and eccentric strengthening; important distinction — eccentric heel drops are contraindicated for insertional Achilles disease (unlike mid-tendon tendinopathy, where they are first-line)
• Corticosteroid injection: Into the retrocalcaneal bursa (not into or near the tendon itself, due to rupture risk) reduces bursitis and provides significant temporary relief
• Extracorporeal shockwave therapy (ESWT): Effective for calcific insertional Achilles tendinopathy — breaks down calcium deposits and stimulates tendon healing

Surgical Treatment

When conservative treatment fails after 6+ months, surgery removes the Haglund’s prominence and addresses associated pathology. The procedure involves:

• Resection of the posterior superior calcaneal prominence (Haglund’s resection) — the amount of bone removed is carefully calculated to eliminate the bony impingement without over-resecting and weakening the calcaneus
• Retrocalcaneal bursectomy — removal of the inflamed bursa
• Achilles tendon debridement — removal of degenerated tendon tissue at the insertion
• Calcific tendon excision — removing intratendinous calcifications when present
• Achilles tendon repair or FHL augmentation — when significant tendon tissue must be removed (>50% of the footprint), the tendon is reinforced with a flexor hallucis longus tendon transfer

Surgery can be performed through a traditional open incision (better visualization, preferred when significant tendon work is needed) or endoscopically (smaller incisions, faster soft tissue recovery). Recovery requires 4–6 weeks non-weight-bearing, followed by progressive weight bearing over 6 weeks, and return to athletic footwear at 3–4 months.

Frequently Asked Questions

When should I see a podiatrist?

See a podiatrist if: foot or ankle pain has lasted more than 2–4 weeks without improvement, you’re changing your gait to avoid pain, you have an open wound or sore that isn’t healing, you notice nail discoloration or thickening, you have diabetes and any foot concern, or pain is severe enough to wake you at night. Most foot conditions are easier and cheaper to treat early — what starts as a minor issue can become a surgical problem with months of delay.

What is the difference between a podiatrist and an orthopedic surgeon?

Podiatrists (DPM — Doctor of Podiatric Medicine) specialize exclusively in the foot, ankle, and lower leg. Orthopedic surgeons (MD/DO) have broader musculoskeletal training but variable foot/ankle subspecialization. For foot and ankle-specific problems, a podiatrist often has more focused training and experience. For injuries involving the leg above the ankle, complex pediatric cases, or multi-level reconstruction, orthopedic consultation may be appropriate. We frequently co-manage patients with orthopedic colleagues.

How do I know if my foot pain is serious?

Signs that warrant same-day or next-day evaluation: severe pain that appeared suddenly without clear cause, swelling, redness, and warmth that appeared suddenly (possible gout, infection, or Charcot fracture), an open wound that looks infected (redness spreading, pus, warmth), inability to bear weight, or any foot problem in a diabetic patient. Pain that’s been present for weeks and is stable is important but not an emergency — schedule within 1–2 weeks.

Can foot problems cause back and knee pain?

Yes — this is a kinetic chain effect. Abnormal foot mechanics (overpronation, supination, leg length discrepancy) cause compensatory changes in knee, hip, and lumbar alignment. Roughly 30% of patients presenting to our clinic with knee pain have a treatable foot-level biomechanical cause. Correcting foot mechanics with orthotics or appropriate footwear often provides significant knee and back relief. If you have chronic knee or back pain and haven’t had your foot mechanics evaluated, it’s worth a consult.

Are orthotics worth it?

For the right conditions, yes — custom orthotics are among the most cost-effective interventions in podiatry. They’re most effective for: plantar fasciitis, flat feet with secondary knee/back pain, leg length discrepancy, metatarsalgia, posterior tibial tendon dysfunction, and diabetic foot pressure management. Quality OTC orthotics ($35–60) resolve symptoms for 60% of patients with mild-to-moderate conditions. Custom orthotics are appropriate when OTC options have failed or when the biomechanical problem is complex. We cast custom orthotics in-office.

How do I choose the right running shoes?

Start with your foot type (flat, neutral, high arch) and running pattern (overpronator, neutral, supinator). Flat feet and overpronators do best in stability or motion-control shoes. Neutral feet do well in neutral-cushioned shoes. High arches need maximum cushioning with flexible soles. Always buy running shoes at the end of the day (foot swelling peaks then), get properly fitted by a specialist, and replace every 300–500 miles. If you’ve been injured repeatedly, a gait analysis can identify the mechanical flaw driving your injury pattern.

What is the difference between a sprain and a fracture?

A sprain is a ligament injury (the tissue connecting bones); a fracture is a break in the bone itself. Both can occur with the same trauma (ankle roll, fall). The old test — ‘if you can walk, it’s not broken’ — is wrong; many fractures are initially weight-bearable. Key differences: a fracture typically produces localized bone tenderness along the bone itself, while a sprain is tender over the ligament. X-ray is the standard to differentiate. High-grade sprains without proper treatment can be as disabling as fractures.

How do I prevent foot and ankle injuries?

The four most impactful prevention strategies: (1) Supportive, appropriately fitted footwear for your foot type and activity. (2) Gradual activity progression — the 10% rule (never increase weekly mileage or intensity by more than 10%). (3) Regular calf and ankle mobility work. (4) Strengthening the posterior tibial tendon, peroneals, and intrinsic foot muscles. Most overuse injuries are preventable; most acute injuries are not — but ankle sprain recurrence (60–70% without rehab) is prevented by balance and proprioception training.
