In numerous legal areas, expert assessments are needed to clarify the causality of herniated discs: Was the damage caused by an accident? The literature mentions specific requirements regarding the trauma mechanism as well as temporal criteria, which prescribe the causality test. These are essentially high-energy traumas with immediate functional impairments. Accident-related MRI examinations are of paramount importance in the expert assessment process to confirm the primary body harm. In examining the causality constituting liability, competitive causes must be assessed. Since the legal requirements of the causality test differ in civil and social law, legal norms need to be taken into account. We present a test scheme that supports the assessment process through entry, implementation and decision-making levels.
