Paget disease (PD) is a chronic metabolically active bone disorder. The spine is the second most commonly involved site; the pathologic changes can cause back pain, myeloradiculopathy, and vertebral fracture. Symptomatic patients are treated medically, and surgery is required when certain complications occur. A case is presented of monostotic vertebral PD treated by percutaneous vertebroplasty (PV) with successful outcome characterized by pain relief and improved disability at 6-month follow-up. PV is proposed as a primary treatment for back pain secondary to PD when unresponsive to conservative therapy and when not associated with other complications.
