title: Radiographic features of bisphosphonate therapy in pediatric patients.
abstract: BACKGROUND
  Pediatric patients are being treated with bisphosphonates for low bone mineral density. Skeletal radiographic findings have been described with bisphosphonates given orally and intravenously.
  
  
  OBJECTIVE
  To determine and describe the radiographic findings of cyclic intravenous bisphosphonate therapy in the growing skeleton.
  
  
  METHODS
  Retrospective review of radiographs of 32 patients with osteogenesis imperfecta or cerebral palsy treated with intravenous bisphosphonates on a quarterly schedule.
  
  
  RESULTS
  Principal observations were metaphyseal bands and increased bone mineral density. The bands varied in spacing according to the age of the patient, rate of growth, and the location of the metaphysis. Fractures continued to be seen in patients with osteogenesis imperfecta.
  
  
  CONCLUSIONS
  Cyclic bisphosphonate therapy results in distinctive radiographic findings in the growing skeleton.
