Biomechanische Studien zur Verankerung von Pedikelschrauben

Zusammenfassung

Dieser Übersichtsartikel befasst sich mit biomechanischen Testungen zur Verankerung von Pedikelschrauben an der thorakolumbalen Wirbelsäule. Es werden verschiedene Verfahren zu Testungen von Gesamtkonstruktionen sowie einzelner Pedikelschrauben erörtert. Im Weiteren werden Ergebnisse bereits durchgeführter Testungen zur Verankerung von Pedikelschrauben diskutiert, in welchen gezeigt werden konnte, dass Adaptionen von Augmentationstechniken und Verbesserungen des Pedikelschraubendesign einen vorteilhaften Einfluss auf die Schraubenverankerung haben. Biomechanische Studien stellen somit ein wichtiges Bindeglied zwischen Entwicklung und Klinik dar.

Abstract

This review article addresses biomechanical testing for pedicle screws anchorage of the thoracolumbar spine. Various methods for testing entire constructions as well as individual pedicle screws are discussed. In addition, results of previous tests on pedicle screws anchorage will be discussed, in which it was shown that adaptations of augmentation techniques and improvements in the pedicle screw design have a beneficial effect on screw anchoring. Biomechanical studies thus represent an important link between development and clinical practice.
