Haglund’s Deformity, also known as Mulholland Deformity or Pump Bump, refers to the abnormal growth in the bony structure behind the heel bone. The condition eventually causes the bursae (located between this bone and Achilles tendon) to become irritated and swollen. Haglund’s Deformity can affect any person although it is more commonly observed in women.


  • Prolonged wearing of hard shoes with a closed back that rubs against the heel bone
  • Genetic deformity in the shape or structure of the heel bone
  • Presence of a high-arched foot
  • Tightness of the Achilles tendon
  • Unusual gait such as walking on the outer side of the heel
  • Running on hard surfaces
  • Excess body weight can stress the heel bone and the tendons
  • Past injuries to the foot or heel


  • Visible outgrowth of the bone behind the heel
  • Considerable pain while walking or wearing shoes
  • The back of the heel feels swollen and tender when touched
  • Redness
  • Tightness in the heel or at the back of the foot while moving


  • Clinical evaluation of the affected foot
  • X-ray imaging may be required to analyze changes in foot structure
  • Analysis of the patient’s gait
  • The symptoms reported by the patient, daily activities as well as type of shoes worn may be taken into consideration to establish the cause and diagnosis


Non-surgical Treatment

  • Using customized orthotic supports may allow even distribution of pressure on the foot and prevent the bone from rubbing
  • Non-steroidal anti-inflammatory medicines may be prescribed by the doctor
  • Use of heel pads may be recommended to prevent pressurizing the heel
  • Ice packs may help to reduce swelling
  • Wearing open shoes may help to reduce pain while walking
  • In severe cases, an immobilizing boot or temporary cast may be recommended

Surgical Treatment

If the Achilles tendon is tight or damaged, surgery may be required to reduce the pressure on the joint. During the procedure, the orthopedic doctor removes the outgrowth and smoothens the bone. Post-surgery, the patient may be recommended to wear soft padded shoes and use crutches to prevent weight-bearing.
