title: [Kyphoplasty and vertebroplasty in fractures in the elderly: effort and effect].
abstract: Kyphoplasty and vertebroplasty are two minimally invasive percutaneous techniques used for treatment of osteoporotic vertebral compression fractures in the thoracic and lumbar spine. The injection of polymethylmetacrylate (PMMA) is often a final attempt at therapeutic treatment of complications due to such fractures. Vertebroplasty involves injection of cement via one or both pedicles under high pressure, thus filling and stabilizing the vertebra without reduction of fracture. Extravertebral cement leakage is a common complication: an intact posterior wall normally prevents cement leakage into the epidural space. Kyphoplasty involves transpedicular inflation of balloon tamps, thus creating a cavity which is then filled with PMMA under low pressure. Restoration of vertebral height is possible and the potential for extravertebral cement leakage lessened.
