title: [External fixators in temporary spinal stabilization. Radiographic anatomy of the lumbar pedicles].
abstract: External spinal fixation is used in cases where fusion is indicated and for reducing the number of stiffened segments in lumbar sacral pain. Owing to the percutaneous implantation, only the pedicle oval is available for localizing the screw in a-p X-rays. Cadaver studies have shown that the root of the arch and the halo are not identical and that unless one relies on the midpoint of the halo the pedicle may be perforated medially. rate, with markedly enhanced fusion of the lumbar spine following external spinal fixation.
