Under what circumstances do you need amputation?
Amputation refers to the surgical treatment of cutting off a diseased limb through bones or joints, and the cut limb cannot be regenerated. In most cases, amputation is a necessary operation to save or prolong the patient's life. Only in a few cases, doctors will amputate disabled limbs that lose their physiological functions, and then install suitable prostheses for patients, which is more conducive to the needs of patients' lives. Doctors are very cautious about choosing amputation. Amputation under severe trauma must cause irreparable damage to the blood supply of the injured limb, such as irreparable damage to blood vessels; Or the tissue structure is destroyed to the point where it cannot be preserved, amputation is taken. The trauma here includes all kinds of bumps, bruises, gunshot wounds, burns, frostbite, electric injuries, malignant tumors and so on. The success of bone grafting depends on the degree of pulverization. As long as there is no defect in the bone, it can be connected, but at the joint, whether the joint still has joint function after connection and whether the connective tissue in the joint can be restored is the key point. If the soft tissue, blood vessels and infection of the wound fester and die, it may expand and spread. In order to stop the upward infection and save lives, amputation should be considered.
