RESUMO
Diabetic foot ulcers (DFUs) is a severe complication of the diabetes mellitus, which is the first leading cause of non-traumatic lower limbs amputations. The pathogenesis of diabetic foot involves a variety of mechanisms, treatment involves the department of foot and ankle surgery, department of vascular surgery, endocrinology, and infection control. Treatment need multidisciplinary diagnosis and treatment. Debridement is the basis of treating diabetic foot ulcers, and the normal anatomical structure should be maintained during the process. Vacuum sealing drainage (VSD) and antibiotic-laden bone cement (ALBC) have more advantages of controlling infection and ulceration wound healing, which could receive good clinical effect. Tendon lengthening could alleviate the problem of ulcer occurrence and progression caused by stress concentration on the bottom of foot, which has widely application and has advantages of preventing formation of foot ulcers. Flap transplantation could solve the problem of wound healing, but it is necessary to consider whether the transplanted flap could bear the same function as plantar tissue. Tibial bone transverse distraction is a relatively new technique, and the mechanism is not clear, but it has certain application prospects from the perspective of clinical efficacy.
