[Syndrome of diabetic foot: modern diagnostic methods].

We summarize the literature data on diagnostics of diabetic foot syndrome including clinical examination and special invasive and non-invasive studies of the vascular system. The main methods are ultrasound dopplerography, X-ray contrast angiography, and ultrasound duplex scanning. Special attention is given to instrumental diagnostics of diabetic neuropathies. The golden standard for the evaluation of the function of the peripheral nervous system is electroneuromyography. Methods for the study of diabetic foot complications, such as osteoarthropathy and trophic ulcers, are discussed.
