Kurzfassung englisch:
The aim of this study was to examine how material properties and placement of bone cement affect the stiffness of augmented vertebral bodies compared to the non-augmented state and the load transfer. Vertebral body slices were scanned with a HR-pQCT and tested in compression before and after augmentation with standard and low-modulus PMMA cement. Pressure sensitive films were placed between both loading plates and the slice to study the endplate load transfer.
Vertebral stiffness is increased significantly only if the filling reaches to both endplates. The modulus of the cement has no significant influence on the stiffness but on the endplate load transfer. Both cements are equivalent regarding vertebral stiffness after augmentation. For the low-modulus cement a more uniform pressure distribution across the endplate is obtained.
