Paget's disease of bone disrupts your body's normal bone recycling process, in which old bone tissue is gradually replaced with new bone tissue. Over time, the affected bones may become fragile and misshapen. Paget's disease of bone most commonly occurs in the pelvis, skull, spine and legs.

The risk of Paget's disease of bone increases with age. Your risk also increases if any of your family members have the disorder. Complications of Paget's disease of bone can include broken bones, hearing loss and pinched nerves in your spine.

Bisphosphonates — the medications used to strengthen bones weakened by osteoporosis — are the mainstay of treatment. In severe cases, surgery may be necessary.
