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.

ConditionHow It Differs
Retrocalcaneal bursitis aloneAnterior to the Achilles insertion, no posterior bone prominence.
Insertional Achilles tendinopathyPain 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.
