Causes Circulatory disorders Diabetic vasculopathy Sepsis with peripheral necrosis Peripheral artery disease which can lead to gangrene A severe deep vein thrombosis (phlegmasia cerulea dolens) can cause compartment syndrome and gangrene Neoplasm Cancerous bone or soft tissue tumors (e.g. osteosarcoma, chondrosarcoma, fibrosarcoma, epithelioid sarcoma, Ewing's sarcoma, synovial sarcoma, sacrococcygeal teratoma, liposarcoma), melanoma Trauma Severe limb injuries in which the efforts to save the limb fail or the limb cannot be saved. Traumatic amputation (an unexpected amputation that occurs at the scene of an accident, where the limb is partially or entirely severed as a direct result of the accident, for example, a finger that is severed from the blade of a table saw) Amputation in utero (Amniotic band) Congenital anomalies Deformities of digits and/or limbs (e.g., proximal femoral focal deficiency, Fibular hemimelia) Extra digits and/or limbs (e.g., polydactyly) Infection Bone infection (osteomyelitis) and/or diabetic foot infections Gangrene Trench foot Necrosis Meningococcal meningitis Streptococcus Vibrio vulnificus Necrotizing fasciitis Gas gangrene Legionella Influenza A Virus Animal bites Sepsis Bubonic plague Frostbite Frostbite is a cold-related injury occurring when an area (typically a limb or other extremity) is exposed to extreme low temperatures, causing the freezing of the skin or other tissues. Its pathophysiology involves the formation of ice crystals upon freezing and blood clots upon thawing, leading to cell damage and cell death. Treatment of severe frostbite may require surgical amputation of the affected tissue or limb; if there is deep injury autoamputation may occur. Athletic performance Sometimes professional athletes may choose to have a non-essential digit amputated to relieve chronic pain and impaired performance. Australian Rules footballer Daniel Chick elected to have his left ring finger amputated as chronic pain and injury was limiting his performance. Rugby union player Jone Tawake also had a finger removed. National Football League safety Ronnie Lott had the tip of his little finger removed after it was damaged in the 1985 NFL season. Criminal penalty According to Quran 5:38, the punishment for stealing is the amputation of the hand. Under Sharia law, after repeated offense, the foot may also be cut off. This is still in practice today in countries like Brunei, the United Arab Emirates, Iran, Saudi Arabia, Yemen, and 11 of the 36 states within Nigeria. In 1779, Thomas Jefferson proposed a bill to the Virginia Assembly that ostensibly would have replaced capital punishment with other penalties, including amputation, for certain crimes, although
