Amputation

Sometimes a part of the body is removed.

This might be a finger or a leg. A doctor can do this to help. It can stop a sickness. It can also help a bad hurt.

Doctors use tools to do this. They might even use a saw. This can happen because of an accident. It can also happen if someone is very cold.

People can use new tools to move again. These tools help them walk or grab things. It is a way to stay healthy.

Amputation is when a part of the body is removed.

This might be a finger, an arm, or a leg. It can happen in many ways.

Sometimes a doctor performs surgery to help a person. They may remove a limb to stop a disease. This could be cancer or gangrene. Gangrene is a sickness where body parts die.

In the past, doctors used curved knives. Today, they use special tools. They must tie off blood vessels first. This stops bleeding. Then they cut the muscle. Finally, they use a saw to go through the bone.

Other times, an amputation happens by accident. This is called a traumatic amputation. It can happen during a war or a bad accident.

Extreme cold can also cause it. This is called frostbite. Ice crystals can form in the skin. This kills the cells.

People can use a prosthesis to help them. A prosthesis is an artificial part. It can help a person walk or grab things again.

Some new tools even use electricity to help move.

Amputation is the removal of a limb or a body part.

This can happen because of an injury, a sickness, or a medical surgery. Doctors sometimes use surgery to stop a disease from spreading. For example, they might remove a part with cancer or gangrene. Gangrene is a condition where body parts die. In some special cases, a baby might be born with a limb missing. This is called a congenital amputation. It can happen when tight bands in the womb cut off a limb.

When a doctor performs this surgery, they follow specific steps. First, they must ligate the arteries and veins. This means they tie them off to prevent bleeding. Next, they cut through the muscles. Then, they use a saw to go through the bone. They must file down any sharp or rough edges on the bone. Finally, they move skin and muscle flaps over the end of the limb. This is called a stump. Sometimes, they attach the muscle to the bone to help it work better. This method is called myodesis.

People have been practicing amputation for a very long time. The oldest evidence was found in a cave in Indonesia. This skeleton was found in the Liang Tebo cave in East Kalimantan. It dates back at least 31,000 years. The person had an amputation when they were a young child. In the 18th century, people used different guides for these surgeries.

Throughout history, amputation has also been used as a punishment for crimes. In 1779, Thomas Jefferson even proposed a bill in Virginia that included amputation as a penalty. That bill never passed because some thought it was too mean.

There are many different types of amputations. For legs, there are minor ones like losing a finger. Major ones include below-knee or above-knee amputations. There are also ankle disarticulations, which happen at the ankle joint. For arms, there are many types too. These include below-elbow or above-elbow amputations. Some people even have facial amputations, like losing an ear or a nose.

Amputation can also happen because of extreme cold. This is called frostbite. Ice crystals form in the skin and kill the cells. In rare cases, a person might even amputate their own limb to escape being trapped. This happened to a hiker named Aron Ralston.

Even though a limb is gone, people can still do many things. Many people use a prosthesis to help them. A prosthesis is an artificial body part. Some new ones are bioelectric, which means they use electricity to help. This can help a person feel sensation again.

Some athletes even choose to have a finger removed to stop pain. For example, a football player named Daniel Chick had a finger removed. This helped him play better. Modern science is always finding new ways to help people use their new limbs.

Amputation is the removal of a limb or another body part.

This process can occur through physical trauma, medical illness, or surgical intervention. In a medical setting, surgeons perform amputations to control pain or stop a disease from spreading. For example, it may be used to treat malignancy, which is another word for cancer. It is also used to manage gangrene, a condition where body tissue dies. In some rare cases, surgery is performed as a preventive measure to stop future health problems. There is also a unique condition called congenital amputation. This occurs when fetal limbs are cut off by constrictive bands while still in the womb.

When a surgeon performs an amputation, they follow a precise sequence of steps. First, they must ligate the supplying artery and vein. To ligate means to tie these vessels off to prevent hemorrhage, which is heavy bleeding. Next, the surgeon performs a transection of the muscles, meaning they cut through the muscle tissue. The bone is then cut using an oscillating saw. After the bone is severed, the surgeon must file down any sharp or rough edges. Finally, they transpose skin and muscle flaps over the remaining part of the limb, known as the stump.

To improve how the stump functions, surgeons may use myodesis. This is a technique where the muscle is attached directly to the bone or its periosteum, the membrane covering the bone. This helps prevent atrophy, which is the wasting away of muscle tissue.

Amputations are categorized by which part of the body is affected. Lower limb amputations are divided into minor and major types. Minor amputations generally involve the removal of digits, such as fingers or toes. Major amputations include trans-tibial amputations, which occur between the knee and the ankle. These are often called below-knee amputations. Other major types include trans-femoral amputations, or above-knee amputations, and hip disarticulations, where the limb is removed at the hip joint.

There are also specific partial foot amputations like the Chopart or Lisfranc procedures. Some advanced techniques, such as rotationplasty, involve turning the foot around and reattaching it so the ankle joint can act like a knee.

Upper extremity amputations follow a similar pattern of classification. These include partial hand amputations and wrist disarticulations. Common arm amputations include trans-radial procedures, which are below-elbow amputations, and trans-humeral procedures, which are above-elbow amputations. Some specialized methods exist, such as the Krukenberg procedure. In this version of a trans-radial amputation, the radius and ulna bones are used to create a stump that can perform a pincer action. Amputations can also affect the face, involving the removal of ears, the nose (rhinotomy), the tongue (glossectomy), or the eyes (enucleation).

Human history shows that amputation has been practiced for thousands of years. The oldest evidence was discovered in the Liang Tebo cave in East Kalimantan, Indonesian Borneo. A skeleton found there suggests an amputation was performed on a young child at least 31,000 years ago. Throughout history, amputation has also been used as a legal punishment. In 1779, Thomas Jefferson proposed a bill in the Virginia Assembly that included various forms of amputation for certain crimes. This included rhinotomy for women. However, the bill never passed because some viewed it as too barbaric and others thought it was too lenient.

In some modern countries, judicial amputation is still used to punish those who commit crimes.

There are many different causes for the loss of a limb. Circulatory disorders, such as peripheral artery disease, can lead to gangrene. Severe infections like sepsis can also cause peripheral necrosis, where tissue dies. Trauma is another common cause, such as injuries sustained during war or accidents involving machinery. Frostbite is a specific type of injury caused by extreme cold. When skin freezes, ice crystals form in the tissue, leading to cell death. In rare, extreme situations, a person might even perform a self-amputation. A famous example is the hiker Aron Ralston, who amputated his own forearm after being pinned by a boulder for five days.

Modern science focuses heavily on restoring function through technology. A prosthesis is an artificial device used to replace a missing limb. Some advanced versions are bioelectric, meaning they use electrical signals to restore sensation or movement. Researchers are also testing the Agonist-antagonist Myoneural Interface, or AMI. This technology aims to give people better control over their prosthetic limbs. Even in sports, amputation can be a choice to improve performance. For instance, Australian Rules footballer Daniel Chick had a finger amputated to relieve chronic pain and help him play better.
