[Correlation between roentgen morphometrically obtained data and cortical thickness indicative of anchorage strength of screws in human cadaver vertebral bodies].
Through the morphometric and histomorphometric examinations on the vertebral of the corpses, a functional connection between roentgenmorphometric plain facts (in transverse- and sagittal diameter of the vertebral body) and the cortical thickness can be established. The stress of the vertebral body through a screw can already preoperatively be assessed by roentgenmorphometric examinations that the cortical thickness plays an important dimension in the anchorage tightening of the screws on the vertebral body. By use of this knowledge the guarantee of operation on vertebral body is raised.
