Introduction: Within the framework of regular revisions of the List of occupational diseases in the Czech Republic there are efforts to extend the List by an item, which could enable to acknowledge diseases of lumbar spine from overload as an occupational disease, specifically with adherence to generally valid national rules, i.e. after fulfilling clinical criteria and objective demonstration of such working conditions, when the occupational disease originates (hygienic criteria). Objective: The communication was intended to clarify the connection between medium severe chronic vertebrogenic syndrome and the work performed, on the basis of an objective method for evaluation of working load exerted on lumbar spine at the individual level.
