Amputation is the last option for surgeon. This is due to the fact that even prosthesis has an appearance as a real arms or legs, but they cannot function naturally, nor do feel as natural limb. Surgeons then try to avoid amputations except in case that doing so will save lives of patients. Examples of cases that will require amputations are:
  1. No blood can pass through to the end of arms or legs. This will cause traumatic pain and will be life-threatening condition.
2. Having wounds that are dangerous to the limbs as they will vastly destroy all skins, tissues, muscles, veins, and nerves.
3. Having serious infection that cannot be controlled with antibiotics which will lead to fatal condition.
4. Having chronic wounds which cannot be healed and can possibly develop into fatal gangrenes, or muscle or cancer
5. Having muscle or bone cancer
