Paget's Disease of Bone: Clinical Features and Treatment

Paget's disease of bone is often discovered incidentally, but can have extensive metabolic and local mechanical complications. Treatment is not required for all patients and should only be undertaken for certain indications, and with a clear understanding of the three types of drugs available. Bone pain unmanageable with analgesics and pathologic fractures are the most common indications, while neurologic symptoms, hypercalcemia and congestive heart failure are less frequent ones. Calcitonin or mithramycin is used for the more urgent indications, and calcitonin or the diphosphonate, etidronate sodium (EHDP), for the more chronic ones. The drugs are generally efficacious and well tolerated.
