Haglund's Deformity – The Pump Bump at the Back of the Heel

Haglund's Deformity – The Pump Bump at the Back of the Heel That painful bump on the back of your heel—the one that rubs against the back of your shoes—might be Haglund's deformity. Also called "pump bump," this condition is a bony enlargement that develops on the heel bone, and it can cause significant discomfort. Many people develop Haglund's deformity in their 20s and 30s, sometimes from genetics, sometimes from footwear, and sometimes from activity patterns. Understanding what causes it and how to manage it can help you find relief and get back to comfortable walking. What Is Haglund's Deformity? Haglund's deformity is a bony bump that forms on the back of the heel bone (calcaneus) where the Achilles tendon attaches. The prominence enlarges and becomes irritated by friction from shoe backs, causing pain and inflammation. The condition got the nickname "pump bump" because it was historically seen in people who wore pump style shoes, particularly high heeled shoes. However, modern cases occur in all types of footwear and in people of all ages and activity levels. The bump itself is actually a enlargement of the heel bone—the bony projection at the back of the calcaneus. It's not a growth or cyst; it's a structural bony change. What Causes Haglund's Deformity? Genetic Factors Haglund's deformity often runs in families. If your parents have it, you're at higher risk of developing it. Biomechanical Factors Flat feet: Overpronation (foot rolling inward) changes how the heel bone sits and how the Achilles tendon pulls High arched feet: Can create abnormal heel angles Tight calf muscles: Create excessive pull on the Achilles tendon, increasing stress on the heel bone Ankle structure: Some people naturally have heel bone shapes that predispose them to enlargement Footwear High heels that increase Achilles tendon tension Stiff shoe backs Tight fitting shoes Shoes with rigid heel counters Repeated friction from shoe backs Activity Patterns Running, especially on hard surfaces Activities that increase calf muscle tension High impact sports Sudden increases in activity level Inflammatory Conditions Arthritis affecting the ankle Inflammatory response to repetitive friction Achilles tendinitis Symptoms of Haglund's Deformity You might experience: Visible bump on the back of your heel Pain in the back of the heel, especially when wearing certain shoes Redness, swelling, or irritation where the heel rubs Pain with walking, especially in shoes with stiff heel counters Achilles tendon pain Pain worse when wearing high heels or certain shoe styles Heel pain that improves with different footwear Inflammation or bursitis in the area Diagnosis Your podiatrist will examine your heel and take a detailed history of your symptoms: Physical Examination We'll assess the prominence of the bone, check for swelling and redness, evaluate the Achilles tendon, and determine what footwear triggers your symptoms. Imaging Studies X rays: Show the bony prominence and its size. Lateral (side view) X rays are most helpful. Ultrasound: Can assess the bursa (fluid sac) that often develops in response to friction MRI: Rarely needed but helpful if we suspect significant Achilles tendon involvement Treatment of Haglund's Deformity Conservative Management (First Line Treatment) Many cases can be successfully managed without surgery: Footwear Changes This is often the most important intervention: Avoid high heels and pump style shoes Choose shoes with soft, flexible heel counters Look for open back shoes like clogs, sandals, or slip on styles Choose athletic shoes with padded heel collars Avoid shoes with rigid heel boxes Consider sneakers or supportive walking shoes Pain Management Ice: Apply ice after activities that aggravate the condition Elevation: Minimize swelling by keeping your foot elevated Anti Inflammatory Medications: NSAIDs reduce inflammation and pain Compression: Elastic bandages or heel sleeves provide support Heel Padding and Shoe Modifications Achilles tendon pads: Specially designed inserts raise your heel slightly, reducing Achilles tension Heel lifts: Small lifts in shoe heels reduce tendon tension Heel cups: Provide cushioning and reduce friction Moleskin or gel pads: Protect the bump area from friction Shoe modifications: Professional cobblers can stretch the heel area or modify the shoe back Physical Therapy Calf stretches: Reduce Achilles tendon tension (most important exercise) Achilles strengthening: Controlled eccentric exercises Other leg stretches: Hip flexor and hamstring stretches reduce overall lower leg tension Corticosteroid Injections Can reduce inflammation and pain, though should be used carefully to avoid weakening the Achilles tendon. Advanced Non Surgical Options Platelet Rich Plasma (PRP): May reduce inflammation Extracorporeal Shockwave Therapy: Stimulates healing and reduces pain Immobilization: Temporary use of a boot in severe cases Surgical Treatment If conservative treatment fails after 3 6 months: Hag
