Pathophysiology of Paget's Disease of Bone

Paget's disease of the bone is a skeletal disorder which results in increased and disorganized bone remodeling, leading to dense but fragile and expanding bones. The identified genetic causes of Paget's disease of bone only explain why bone is destroyed, but not why the bone formed in its place is abnormal. Current treatment for people with Paget's disease of the bone is limited to patients with bone pain, thought to be related to high rate of bone turnover (breakdown and rebuilding of bone) and works by slowing down the rate of bone breakdown. The current treatment does not address the excess blood vessels and bone formed. This research is being done to understand factors that may promote blood vessel and bone formation in Paget's disease of the bone.
