Clinical research continues to con?rm that no truth is total care of the severely traumatized patient in the ?rst more transitory than that in the sphere of scienti?c hours following the accident. knowledge. Developments in the ?eld of traumatology at The further development of the AO/ASIF concept led the end of this century provide a striking example of to today s comprehensive craniofacial surgery in the this. As early as 1890 Lambotte carried out osteosynthe- ?elds of traumatology, orthognatics, tumor, and rec- ses with plates and screws. These remained a mere epi- structive surgery. sode, however, until Danis renewed the idea of internal AO/ASIF courses contributed fundamentally to the ?xation 50 years later.
