Haglund deformity, also known as a pump bump or Bauer bump or Mulholland deformity, is defined as bony enlargement formed at posterosuperior aspect of the calcaneum. This deformity leads to retrocalcaneal bursitis.

Pathology

It may result secondary to chronic pressure of rigid shoes.

Radiographic features

Plain radiograph

Bony prominence is seen on postero-superior aspect of calcaneal tuberosity. Repeated trauma to bursa leads to loss of flat planes secondary to retrocalcaneal bursitis. Soft tissue swelling can also be seen on plain radiograph.

MRI

MRI is helpful in detecting the degenerative changes that occur within the Achilles tendon. Also useful to the surgeon to know the extent of the degenerative changes.
