title: [Extended kyphoplasty indications for stabilization of osteoporotic vertebral compression fractures].
abstract: OBJECTIVE
  Percutaneous vertebroplasty with polymethylmethacrylate allows minimally invasive stabilization of osteoporotic vertebral fractures. Fracture reduction is, however, not possible and the risk of uncontrolled epidural cement leakage with burst fractures is increased. Kyphoplasty, in contrast, allows a degree of fracture reduction and provides an extended spectrum of indications through open approaches, which enable spinal decompression and augmentation of incomplete burst fractures. METHODS. In kyphoplasty a contrast-filled balloon is inflated in the vertebra until a cavern is created. A degree of reposition may be achieved depending on fracture age. Augmentation is performed with high-viscosity polymethylmethacrylate under low pressure. In cases of neural compression, interlaminary spinal decompression and kyphoplasty through the posterior wall is performed. With anterior spinal procedures, kyphoplasty can be performed without extending the approach.
  
  
  RESULTS
  Vertebral augmentation was performed by percutaneous, interlaminary, and anterior approaches for incomplete burst fractures. Four representative cases are presented from a collective of 120 augmentations.
  
  
  CONCLUSIONS
  Percutaneous kyphoplasty, supplemented by open approaches, enables augmentation of osteoporotic incomplete burst fractures.
