Video - Paget disease of bone

Paget's disease of bone, also known as osteitis deformans, is a chronic bone disorder that causes the bone to become thick, weak, and deformed. It commonly affects the pelvis, femur, and lower lumbar spine though it can affect any bone in the body.

Paget disease is associated with an increased risk of fractures, arthritis, and bone tumors. Symptoms may include pain in the affected bone or due to arthritis or nerve impingement. Treatment involves medications to slow the progression of the disease, such as bisphosphonates, pain relievers, and surgery to correct deformities or stabilize fractures.
