The assessment of congenital foot deformities is only relevant in the context of German legislation (SchwbG) defining disability and fitness for military service. All assessments of congenital foot deformities should be based on the twin concepts of function and capacity to withstand stress. However, assessments with regard to the degree of disability and fitness for military service will occasionally differ. This article discusses the various congenital foot deformities individually, allocating them to the respective degrees of disability [as laid down in German law]. The classification may serve as a guide for consultants within the context of disability legislation and for ascertaining fitness for military service in accordance with the "Central Standing Orders" of the Federal German armed forces.
