Diabetes mellitus is the number one cause of lower extremity amputation (LEA) in the United States, accounting for about 60,000 cases per year. While the combination of reduced blood supply and the loss of sensation to the foot in a diabetic are responsible for the high incidence of LEAs, in most cases it is the loss of sensation that is primarily responsible for the initial foot wound and its failure to heal. The authors review the four mechanical causes for foot ulceration and eventual amputation. Based on an understanding of how feet ulcerate, the National Foot Treatment Center in Carville, LA has developed an insensitive foot screening and treatment program for "diabetic" foot ulcers that is more than 90% effective in healing plantar ulcers.
糖尿病是美国下肢截肢（LEA）的首要原因，每年约有6万例。虽然糖尿病患者足部血液供应减少和感觉丧失共同导致了下肢截肢的高发病率，但在大多数情况下，感觉丧失是导致最初足部伤口及其无法愈合的主要原因。作者回顾了足部溃疡和最终截肢的四个机械性原因。基于对足部溃疡形成方式的理解，路易斯安那州卡维尔的国家足部治疗中心针对“糖尿病”足部溃疡制定了一项感觉迟钝足部筛查和治疗计划，该计划在治疗足底溃疡方面的有效率超过90%。
