Zusammenfassung
Aufgrund der steigenden Zahl an alten und osteoporotischen Patienten steigt auch die Inzidenz komplexer Wirbelsäulenoperationen, bei denen ein Wirbelkörperersatz in diesem Kollektiv notwendig wird. Durch den Einsatz zementaugmentierter Schrauben konnte die Lockerungsrate bei dorsalen Eingriffen deutlich reduziert werden. Gleichsam ist es bei ventralen Eingriffen möglich die Endplatten so mit Zement zu verstärken, dass Cagesinterungen vermindert werden können. Die Technik ist einfach, schnell und sicher, da die Nadeln unter visueller Kontrolle gesetzt werden können. In einer ersten Serie von 20 Patienten konnten weder operationsspezifische Komplikationen noch aseptische Lockerungen festgestellt werden.
Abstract
Due to the increasing number of elderly patients with osteoporosis, the incidence of more complex operations demanding a vertebral body replacement is increasing in this population. Cement augmentation of pedicle screws helps to prevent screw pullout. Similarly it is possible to augment the end plates in anterior spine surgery in order to prevent cage subsidence. The technique is simple, quick and safe, as needles can be placed under visual control. In a series of 20 patients neither surgery-related complications nor aseptic loosening were found.
