The aims of internal fixation of thoracic and lumbar spinal fractures are immediate stability, preservation of spine mobility, and restoration of the anatomical form of the vertebra and of the canal diameter at acceptable risks. All these aims together can be achieved only by short posterior pedicle fixation systems, such as the external spine fixator, the(More)
UNLABELLED Ketamine and midazolam, applied as intravenous medication for conscious sedation in day-case maxillo-facial surgery, has been proven to be superior to pentazocine and midazolam concerning cardiovascular parameters and respiratory depression. The aim of this study was to evaluate the effects of low-dose ketamine/midazolam on anxiety, analgesia,(More)
A new system of operative fixation of thoracolumbar and lumbar spine fractures is presented: the 'fixateur interne' (F.I.). From a posterior approach long Schanz screws are inserted through the pedicles into the body of the two vertebrae just adjacent to the lesion and connected by th threaded F.I. rods. By tightening the nuts the Schanz screws are fixed in(More)
The Fixateur Interne has been proposed for limited pedicle fixation of thoracolumbar spine fractures with the assumption that motion in the nontraumatized spinal segments could be maintained. To date, no data exist that both localize and quantitate spinal mobility about the fractured vertebra. Voluntary maximum lateral flexion and extension radiographs were(More)
From a posterior approach long Schanz screws are inserted through the pedicles into the bodies of the two vertebrae just adjacent to the lesion and connected by the threaded Fixateur-interne-rods. By tightening the nuts the Schanz screws are fixed in all directions. The advantages of the F.I.-system are: excellent reposition by the long lever-arm of the(More)
