Difficulties in the Treatment of Diabetic Foot and Research Progress of Combination of Traditional Chinese and Western Medicine

A diabetic foot is any disorder directly attributable to peripheral arterial disease (PAD) and/or the sensory neuropathies influencing the diabetic foot; it is a long-term (or “chronic”) complication of diabetes. Generally, it is a permanent (or “chronic”) comorbidity of diabetes. The swallowing of peripheral neuropathy and peripheral vascular disease leads to damage to the soft tissue, bone, and joint system of the foot. In addition, diabetic feet are also susceptible to infection, which can lead to lameness and even amputation. The management of the diabetic foot can be both challenging and chronic; it may comprise orthoses, surgery, antibacterial medication, and topical dressings. Traditional Chinese medicine (TCM) has a variety of methods for the treatment of diabetic foot with obvious advantages, which can be divided into internal treatment and external treatment of TCM. These treatments include external foot bath, fumigation and washing stains, internal administration of traditional Chinese medicine, syndrome differentiation and staging treatment, empirical prescription, self-made prescription, internal use of proprietary Chinese medicine, massage, acupuncture, and paste powder application, which have significant value in the prevention and treatment of diabetic foot. Some studies have shown that modern medicine combined with herbal therapy can significantly improve the prognosis of diabetic foot. Therefore, this study summarized the difficulties in the therapeutic approaches to diabetic foot and the recent research progress in combining Chinese and Western medicine in the treatment of diabetic foot.
