A Haglund’s deformity is a bony enlargement (bump) at the back of the heel bone. This bump can be present for years without causing any pain or issues. It is often referred to as a pump bump because of the firm backs of pump-type shoes that rub against the back of the heel.
It is the rubbing of soft tissues at the back of the heel against this bony enlargement that leads to the onset of painful symptoms, as opposed to pain from the bony enlargement itself.
