Options for patients with trauma to the spinal column are many and somewhat controversial. Initial experiences with internal fixation (wiring of spinous processes, Meuring-William plates, and the like)were proved to be less than ideal and led many physicians to advocate a nonsurgical spproach. Today, however, improved surgical fixation systems and techniques, combined with incresed knowledge of the biomechanics of injury and need for a better reduction of fractures, have made surgical intervention of stabilization, reduction, and fusion of the traumatized spine widely accepted. In 1977 Magerl was the first to introduce a new biomechanical principle when he connected the long percutaneous Schantz screw anchored dorsally and transpedicularly into the bodies with a stable external frame. This "fixateur externe made" it possible to leave the four-point fixation and to shorten the instrumented area. Following Magerl's ideas, a fully implantable and stable spine fixation device was developed by Dick at Basle University Orthopaedic Department in Switzerland. This is called "fixateur interne" instrumentation. Now, under local anesthesia we would like to present out experiences uning "fixateur internein" the form of external fixation for those spine fractures with unfavorable conditions to operate. In unfavorable conditions, external fixation with this internal fixator may give several advantages, they are l. easy nursing care 2. early mobilization 3. early rehabilitation 4. useful as temporary of first aids measure 5. short operation time.
