The mission of the organization is to be a forum for the 8 National societies for exchange of common Nordic issues regarding evidence based medicine, education and research (register studies). The Nordic Orthopaedic Federation plays an important role in the continuing education of young orthopaedic surgeons and residents in the Nordic countries.
