Leg amputation is the surgical removal of legs either above or below the knee. This surgery is carried out as a result of poor blood circulation because of damage or narrowing of the arteries. As a result the blood cells in these region get deprived of oxygen and nutrients which in turn lead to infection and necrosis of the tissues.
Amputation is also carried out due to injuries from accidents and burns, infections which are incurable with antibiotics,blood clots, cancerous tumor at the region, diabetes and nerve thickening and to prevent the disease from spreading farther into the body. The purpose of the surgery is to restore one’s ability to function and improving total health.
The procedure for amputation is done under general anesthesia or with spinal anesthesia.
