AMPUTATION
The term amputation, refers to removal of all or part of a body part, mostly a limb or an appendage(a body part other than the head and the trunk of the body)
It can also be defined as, a surgical removal of part or all of a limb. It may be used as an emergency option to save life, reduce pain, cut patient cost,and terminates other psychological issues.
Amputation of a body part becomes an option if all interventions from medical professionals have been futile, and leaving the part in a state most likely to cause death of the patient, or result the patient to have lots of pains, stress, and other psychological problems.
CAUSES:
A person can experience a traumatic amputation from a motor vehicle, occupational or industrial accident or combat injury.
Traumatic injury accounts for about 45% of all amputations. A body part can be cut off or torn away in a severe accident, or it can be so badly damaged from a crush injury or severe burns that it cannot be saved.
If tissue destruction, infection or disease affects a body part in a way that makes it impossible to repair or endangers the person’s life, that part may be removed by surgical amputation(Figure 13)
Trauma or disease that cuts off blood flow to a body part for an extended time can also cause tissue death requiring an amputation. An example is frostbite, which can damage the blood vessels in fingers and toes, eventually requiring their removal.
About 54% of all surgical amputations result from complications of vascular diseases and other conditions that affect blood flow, such as diabetes and peripheral arterial disease (PAD).
Chronic vascular problems can lead to tissue death in toes, feet and legs. Of patients undergoing amputation for complications of these diseases, nearly half will die within five years of the amputation procedure.
Removing a hand, foot, arm or leg to prevent the spread of certain types of cancer account for less than 2% of amputations. Cancers such as sarcomas can affect bone and soft tissue in the limbs, and if the cancer is too large or aggressive to be removed, if it is recurring, or if it extends into the nerves or blood vessels, amputation might be necessary.
Advanced cancers affecting the upper leg can result in an amputation procedure called hip disarticulation, which removes the entire femur (thigh bone) from the pelvis.
Severe sepsis is also known as septicemia or blood poisoning can also warrant amputation.
Septicemia happens when drug-resistant bacteria overwhelm the body and spread throughout the bloodstream. Sepsis can affect blood flow and cause tissue to die, especially in the toes, fingers, hands and feet. Severe sepsis can be deadly if antibiotic medicines cannot control the infection.
One cause of sepsis is meningococcal bacteria, which cause a serious form of meningitis(an inflammation of the coverings of the brain and spinal cord).
Methicillin-resistant staphylococcus aureas (MRSA), also a bacterium, can cause a severe condition called necrotizing soft tissue infection, or fasciitis. For these and other dangerous infections occurring in a body part that the patient can survive without, an amputation might be necessary to save the person’s life.
As amputation is performed only involving any part of a limb, it has been grouped into two main types as upper and lower limb amputation as addressed below;
UPPER EXTREMITY AMPUTATION:
Partial hand amputation: removing part of the hand
Wrist disarticulation: removing the hand after separating it from the lower arm at the wrist.
Below-the-elbow amputation: removing part of the lower arm by cutting across the bones of the lower arm (radius and ulna)
Elbow disarticulation: removing the lower arm after separating it from the upper arm at the elbow.
Above-the-elbow amputation: removing the lower arm, elbow and part of the upper arm by cutting across the upper arm bone (humerus)
Shoulder disarticulation: removing the entire arm after separating it from the shoulder
Forequarter amputation: removing the arm and part of the shoulder (shoulder bones could include the clavicle and scapula
LOWER EXTREMITY AMPUTATION:
Partial foot amputation: removing part of the foot (there are many types of partial foot amputation)
Ankle disarticulation: removing the foot after separating it from the lower leg at the ankle
Below-the-knee amputation: removing the foot and part of the lower leg by cutting across the bones of the lower leg (tibia and fibula)
Knee disarticulation: removal of the lower leg by separating it from the upper leg at the knee
Above-the-knee amputation: removal of the lower leg, the knee and part of the upper leg by cutting across the upper leg bone (femur)
Hip disarticulation: removal of the entire leg by separating it from the pelvis at the hip joint
Pelvic amputation, or hemipelvectomy: removal of the entire leg and part of the pelvis.
Double amputation is removal of both hands, feet, arms or legs.
