END-STAGE COMPLICATIONS OF DIABETIC NEUROPATHY - FOOT ULCERATION

Diabetic polyneuropathy is a major complication of diabetes mellitus that frequently leads to foot ulceration. Because of economic impact of foot ulceration and subsequent amputation, major initiatives are under way in the United States and the United Kingdom to reduce their incidence by up to 50%. Although diabetic ulcers may have an ischemic and neuropathic component, the majority are neuropathic. Results from studies have shown a strong association between the neuropathy and the subsequent development of foot ulcers. However, other predisposing factors such as high foot pressures, inappropriate footwear, and other extrinsic pressure usuary must be present, together with neuropathy, to cause foot ulcers. Therefore, the challenge to the physician is to identify the patient at risk and intervene so as to educate and prevent the occurrence of foot ulcers.
