Minimal-invasive Osteosynthesen (MIO) sollten heutzutage ins Repertoire jedes unfallchirurgisch tätigen Operateurs gehören. Entsprechend dem Bestreben jedes Chirurgen, dem Patienten durch den Eingriff selbst möglichst wenig Zusatzschaden beizufügen, stellt die Reduktion des Ausmaßes der Invasivität eine logische Entwicklung dar. Der Begriff «MIO» umfasst folgende Kriterien: Frakturzone nicht freigelegt, Reposition durch indirekte Manöver oder perkutan via Joysticks, kleine Zugänge zur Applikation der Implantate, intraoperative Überprüfung der Reposition und Implantatlage mittels Bildgebung (Röntgen-Bildverstärker, Arthroskopie, Endoskopie, etc.). Schon lange vor der Definition der sogenannt «minimal-invasiven Chirurgie» wurden Frakturen mit gewissen Techniken versorgt, die eigentlich dem Begriff der «Minimal-Invasivität» vollumfänglich gerecht werden, wie z.B. Stabilisierungen mittels Fixateur externe oder geschlossenem Marknagel. In den 90er Jahren des 20. Jahrhunderts erfolgten dann erste Operationen mit «eingeschobenen Platten», einer Technik, die sich in den letzten fünf Jahren unter dem Begriff MIPO (minimal-invasive Plattenosteosynthese), insbesondere dank der neuen winkelstabilen Schrauben-Plattensysteme LISS und LCP, weiter verbreitet hat. Klares Hauptproblem der MIO ist und bleibt die Frakturreposition (kein direktes offenes Manipulieren möglich) mit ihrer intraoperativen Überprüfung (keine direkte Visualisierung). Die Balance zwischen Ausmaß der Invasivität und erreichter Qualität der Reposition und Stabilität ist oft schwierig zu finden und muss von multiplen Faktoren (Frakturlokalisation und -typ, lokale Weichteilsituation, Knochenqualität, Patientenalter und -ansprüche, vorhandene Implantate, Erfahrung des Chirurgen, etc.) abhängig gemacht werden. Neue Technologien wie verbesserte Bildgebung, intraoperative Navigation und perkutane Repositionshilfen werden dazu beitragen, die Invasivität eines operativen Eingriffes auch in der Frakturversorgung weiter reduzieren zu können.

Abstract Importance of Navigation Navigation and intraoperative imaging have undergone an enormous development in recent years. By using intraoperative navigation, the precision of pedicle screw implantation can be increased in the sense of patient safety. Especially in the case of complex defects or tumor diseases, navigation is a decisive aid. As a result of the constantly improved technology, the requirements for reduced radiation exposure and intraoperative control can also be met. The high costs of the devices can be amortized, for example by a reduced number of revisions. This overview presents the principles of navigation in spinal surgery and the advantages and disadvantages of the different navigation procedures.

Background: The palatal rugae are special constructions that are inalterable in their position and pattern during the lifestyles of an individual. This imparts them an exceptional role in the forensic dentistry and may play potential role in malocclusion identification. This study was aimed to see association of rugae pattern with sagittal skeletal malocclusion in orthodontic patients visiting tertiary care hospital. Methods: This cross-sectional examination was completed on pretreatment records (lateral Cephalometric radiographs and maxillary dental casts) of 384 subjects at the orthodontic department of Ziauddin Dental Hospital, Karachi. The study duration was from January to July 2019. The samples were sub-divided into three sagittal skeletal groups based on ANB angle proposed by Steiner’s on lateral Cephalometric radiographs (Class I with ANB angle between 0° to 4°; Class II: ANB angle greater than 5°; Class III: ANB angle less than 0°). The shapes of three most-anterior primary rugae were then evaluated bilaterally using Kapali et al., Classification. Chi Square test was applied to find association of rugae pattern among sagittal skeletal malocclusions groups. Results: Circular and curved rugae shapes were the most prevalent in all skeletal malocclusions. The primary palatal rugae pattern was seen to be significantly different among three skeletal malocclusion groups (p<0.05). The right and left sided palatal rugae pattern showed significant difference in all three skeletal malocclusion groups (p<0.05). Conclusion: The present study showed no specific palatal rugae pattern associated with sagittal skeletal malocclusion. Further studies on larger sample and use of modern 3D technologies to scan the maxillary casts are required for results that are more precise.
