[Data on the static and dynamic rigidity of the calvaria (author's transl)].

Our investigation, carried out on the calvaria of a cadaver, gave us numerical values for the scientific cognition of the static and dynamic flexion- elasticity of the bones of the calvaria. The investigations were carried out with a DYNSTATT type, pendulum-system, flexion-elasticity examining apparatus. On the basis of the measured values three value groups could be established and correspondingly, well-separable regions on the calvaria. While the dynamic static resistance of generally higher value decreases with the progress of the circle, the static resistance rises with approximately identical values. The collateral fractures - indirect fractures - observed beside the direct fractures of the calvaria develop on the parts of the bone around the directly damaged bone region which show relatively smaller static and dynamic resistance.
