Paget's disease of bone

Abstract

Paget's disease of bone is a common disorder of older patients that may sometimes cause a variety of signs and symptoms referable to the skeleton. An intrinsic bone-remodeling abnormality in this disease may lead to bone deformity, pain, and various arthritic or neurologic complications. Characteristic radiographic changes can be seen, and typically the serum alkaline phosphatase level and total urinary hydroxyproline excretion are elevated. Current therapies that interfere with excess osteoclast activity are helpful in many cases, but treatment choices and expected responses must be considered in the context of the individual patient.
