[Experimental studies on the compression resistance of the head with special reference to the mechanism of fractures in traffic accidents].

Compressional resistance of the head and its role in the mechanism of fractures in traffic accidents were studied in five formalin-fixed heads. Before and after the experiment X-ray examination was carried out. Because of the variability of fractures coming into being, it was difficult to distinguish definite types. Nevertheless, experimentally produced fractures appeared to be nearly the same, as those seen in clinical practice.

[Characteristic Biomechanical values for the hip joint (author's transl)].

Four human hip joints which had been fixed informaldehyde taken from human corpses (average age at death: 72 years) were subjected to pressure along defined axes and tested for static strength and elasticity, the hip joint being regarded as a system. The stress-strain curve reveals no definite linearity. The deviations from Hooke's elasticity found in this way have been explained by the fact that not only completely elastic bone, but also plastic components (cartilage of the joint) were tested. The maximum breaking strain, the modulus of elasticity and the elasticity coefficient were also determined. Only about 50% of all fractures observed on the test set-up were diagnosticised radiologically. The parameters which have, in the past, been determined only on models have thus been replaced by experimental results obtained on actual hip joints.

[The influence of inhomogenity on strength of bones (author's transl)].

The authors experiments (n = 50) and calculation (n = 1000) with human hollow bone revealed physical and chemical data which were compared. It was shown that the physical and chemical properties are different in the diaphysis and epiphysis. These regularities are the consequence of the physical and chemical inhomogenities. These findings can be explained as a mechanism of protection.
