Die Wiederherstellung und Erhaltung der ursprünglichen Geometrie eines gebrochenen Knochens wird bei erschwerten Heilung sbedingungen mit Führungselementen, wie Schienen, Schraubplatten und luarknägul erzielt. Sie sind neist aus Cr-ITi-Eolegierten , unmagnetischen Stählen gefertigt und besitzen neben ihrer Funktion aer Kiiochonführung keinerlei besondere Vorteile,, Vor'allem wird die Heilungsdauer eines Bruches damit nicht verkürzt. Ein Nachteil zeigt sich bei ihrer Anwendung in der Zunahme aer Infektionagefahr0 The restoration and preservation of the original geometry of a broken bone is achieved in difficult healing conditions with guide elements such as splints, screw plates and luarknägul. They are usually made of Cr-ITi-alloyed, non-magnetic steels and, in addition to their function of guiding the kochon, have no particular advantages. Above all, they do not shorten the healing time of a fracture. A disadvantage of their use is the increase in the risk of infection 0
