Diabetic foot ulcers are one of the more common complications of diabetes, and non-healing foot ulcers and their complications are the number one cause of diabetic amputation. According to statistics, more than 2.5 billion people worldwide suffer from diabetes, and it is expected to reach 3.8 billion by 2025, with the incidence of diabetic foot ulcers ranging from 15% to 25%, and a recurrence rate of 70% within five years of a history of foot ulcers. Some experts judge that somewhere on the planet, every 30 seconds, there is always a patient who has undergone an amputation due to diabetes. Every year, health care invests a lot of money in diabetic foot ulcers, costing nearly $17,500 for a simple foot ulcer and $30,000-$33,000 for an amputation. In some countries in Europe and North America, the cost of diabetic foot ulcers accounts for 7% to 20% of the total cost of diabetes. The traditional treatment of foot ulcers is based on medical treatment with symptomatic treatment such as debridement, skin grafting or flap grafting for the developed foot ulcers, which is a complicated process and the results are not yet certain. According to the literature, peripheral nerve release as a preventive surgery for diabetic foot ulcers has a better preventive effect, but its theoretical basis and general surgical method are under continuous refinement and improvement.
