Abstract:
Lower extremity amputation is one of the worst complications of diabetes, as it usually has a life expectancy that is below that of most cancers. Four local biologic factors-ulcer, ischemia, neuropathy, and infection-have been shown to be related to amputation. These factors interact with one another, such that neuropathy has been shown to cause ulcers and ischemia and to prevent the healing of ulcers. In addition, ischemia and neuropathy are independent risk factors for infection. More coordinated efforts are needed to create better grading schemes and therapeutic protocols.

Factors Affecting the Risk of Infection
The integrity and count of the white blood cells help the body resist pathogens and fight infection. When impaired, it reduces the body's resistance to pathogens. The acidic pH levels of the gastrointestinal, genitourinary tracts, and skin create...
