Definition

Paget disease (PD) is a bone disorder. Normal bone is always being broken down and built again. With PD, bones are broken down too fast. New bone is loose and bulky instead of strong and compact. This leaves bones weak. They may bend over time. Early treatment can improve outcomes.

PD affects the bones of the:

  • Pelvis
  • Legs
  • Skull
  • Spine

Causes

The exact cause is not known. It may be due to a viral infection, such as the measles.

Other things that may raise the risk are:

  • A faulty SQSTM1 gene
  • Having a family member with PD, such as a parent, sibling, or child
  • Tobacco use

Symptoms

  • Bone and joint pain
  • Bones that do not look the way they should
  • Problems hearing

  • Medicines, such as:
    • Pain relievers, such as acetaminophen and non-steroidal anti-inflammatory drugs (NSAIDs)
    • Bisphosphonates to prevent the loss of bone and keep the disease from getting worse
  • Calcium and vitamin D supplements
  • Assistive devices, such as canes and shoe lifts

People who are not helped by these methods may need surgery to realign bones.

Prevention

There are no known ways to prevent this health problem.
