[Mechanical tolerance of tentorium cerebelli (author's transl)].

In some cases of accidents primary traumatic brain stem hemorrhages are seen in conjunction with lesions of the tentorium cerebelli. In order to decide, whether accelerations of the infra- or supratentorial brain tissue are actually capable of causing tentorium lesions, burst and teartests of tentorium tissue were conducted. The mean dynamic biaxial tearing force was found to be about 4 bar. This value supports the hypothesis that a main injury causing factor of the tentorium in cases without skull fracture could be the relative motion between the tentorium and the brain hemispheres. The mass of the cerebellum however seems to be insufficient to cause such injury producing deceleration forces on the tentorium.

[Etiology and prevention of pelvic injuries in traffic accidents].

With hospitalized traffic accident victimes fractures of the pelvis are not very frequent (4-10%). Fatal cases show a higher fracture incidence (20-25%). Pedestrains are with regard to pelvic fractures twice as frequently affected as other road users. Pedestrians over 60 years of age are most often involved. Modifications of the car front structure are expected to lead to significant improvements for the unprotected road user. Seat belts are capable of reducing pelvic fracture with car occupants only in certain frontal collisions. However, the geometry of the lap belt portion is of importance for the overall effectiveness of the belt system.
