Created from Britannica articles using AI. AI can make mistakes, so verify using Britannica articles.

Paget disease of bone is a chronic condition characterized by the excessive and disorganized breakdown and formation of bone tissue. While the disease can affect almost any bone in the skeleton, it most commonly occurs in the following areas:1

  • Femur (thigh bone)1
  • Pelvis12
  • Skull12
  • Spine (vertebral column)12

Although many patients are asymptomatic, those with advanced disease may experience bone deformities, such as a large skull, a shortened spine, or bowed legs and thighs. Because the affected bone becomes dense and brittle, it is also prone to fractures.12
