[Insurance medicine and accident surgery].
A definition of insurance medicine is presented with due consideration for national peculiarities (social insurances) in Switzerland. The historical development from original trauma-directed accident medicine to the present-day insurance medicine with its more comprehensive nature is shown with particular consideration being given to the close connection with traumatology (trauma surgery/orthopaedic surgery). The guarantee of smooth-running and constructive cooperation between traumatologists and welfare organizations is one of the major tasks of doctors employed in insurance companies, whose sphere of influence and qualifications are under discussion.
