Background
Amputation refers to the removal of the distal end of a limb, which is a medical surgical treatment. Amputation is divided into small amputation and large amputation. Small amputations are open partial amputations with limited removal of tissue by partial revascularization or limb correction while simultaneously removing infected and necrotic tissue. Large amputations are procedures that fail to alleviate serious disease states through revascularization, drug control, or small amputations. Large amputations are generally performed in cases of diseases such as osteosarcoma, osteocarcinoma, or accidents such as car accidents, wherein the survival rate of amputation of patients caused by external accidents is basically the same as that of normal people.
