[The diabetic foot].

In the last 20 years the prevalence of diabetes in Germany has increased by approximately 50%. Associated with this is a distinct rise of diabetes-induced comorbidities and long-term consequences. One of the most frequent consequences is the diabetic foot or the diabetic foot syndrome. This is an ulceration of neuropathic and angiopathic origin, which often reaches a chronic stadium due to a poor healing tendency. Despite the disease management program for diabetes in Germany which mainly concentrates on the prophylaxis and multidisciplinary treatment of chronic diseases, there are approximately 250,000 patients with lesions of the foot caused by diabetes of which approximately 50% have to be amputated within 4 years. To achieve a reduction of the amputation rate identification of the main reasons is necessary. In addition a professional therapy of the vascular disorders and a stage-adjusted wound therapy have to take place in an interdisciplinary collaboration in a centre for wound care. Last but not least this aim can only be achieved by a preventive education of diabetics.
