[Contribution of the specialist in foot surgery to the treatment of the diabetic foot].

Prophylaxis plays an important role in the treatment of the diabetic foot. To prevent perforating plantar ulcers, static disorders should be treated by the use of an orthopaedic sole for improved weight distribution and prevention of hyperkeratosis. Minimal preventive surgery should be employed in cases with anterior foot deformities, to avoid complications from ill-fitting shoes. Therapy for the lesions themselves : bursitis, toe infections, necrosis, perforating plantar ulcers, includes general treatment of the diabetes, antibiotic therapy, vascular agents, bed rest with active mobilization, and appropriate local measures that are often prolonged and require great perseverance. Follow-up surveillance after healing is necessary to avoid recurrences.
