Necessary precondition for acceptance of spine disorders as occupation
al disease is an excessive occupational exposition, its compatibility
with and an explicit causal relation to this disorders. The latter may
be assumed in case of multisegmental spondylosis of the column, combi
ned with local impairment of function and pain, if the vertebral disor
ders of the occupationally exposed column-segment are significantly wo
rse than those of other vertebral segments. Finally non-occupational,
preexisting discrete vertebral disorders (e. g. scoliosis, spondylolis
thesis) have to been excluded. So far there are no alternatives or rej
ections to this consensus, called ''Hamburg formula''. It should be us
ed as long as no other valid, positive markers of occupationally cause
d disorders can be defined on the basis of reliable epidemiological in
vestigations.
