Sometimes in life, unexpected things happen. Whether it's an accident, a medical condition like diabetes, or a congenital condition, it's normal to worry about whether you'll ever be able to get up and walk again. But with today's advanced medical technology, that's no longer a dream. With the use of an artificial leg, that is, a leg that can be strengthened, many people have been able to resume their daily activities and lead an active life. So let's talk about this from the beginning.
Simply put, what is an artificial leg?
A prosthetic leg, medically known as a ``Lower Limb Prosthesis'', is a prosthetic device that replaces all or part of your leg. It is used as an aid to walking, whether after amputation or due to a congenital defect.
This can cover any part of your leg you need. That means it can be made from the foot, ankle, shin, knee, thigh, and even up to the hip. The main goal of this is to give you the ability to walk on your own again, do your own things , and lead a more active life.
Additionally, using a prosthetic leg helps maintain the health of the other bones and muscles in your body because your body weight is distributed evenly on both sides, preventing excessive stress on one side.
What are these artificial legs made of?
Unlike the heavy wooden legs of the past, artificial legs are now made of very strong, yet lightweight materials . For example:
- Carbon Fiber
- Fiberglass
- Titanium
- Aluminum `(Aluminum)`
In addition to these hard parts, there are also soft parts like foam cushioning and silicone sleeves for comfort.
Mechanical springs and gears are used to control movement at joints, such as the knees and ankles. Some advanced prosthetic legs even have computer microprocessors. These allow for very smooth, natural movements when walking.
How does it look?
Prosthetic legs come in a variety of shapes. Some look very technical, like a robotic leg. Others look like a normal skeletal structure. You can also put a covering, or 'skin', of your choice over the prosthetic leg.
Some people decorate their legs with beautiful fabrics, logos, or tattoos to match their personality. Others paint them to match their real legs, making them look very natural. Many of these covers are made to be removable.
What are the main types of prosthetic legs?
Artificial legs are mainly classified according to the level at which your leg is removed (amputation level). Simply put, there are two types: below-the-knee and above-the-knee .
Below-the-knee and above-the-knee prosthetic legs
This level determines the complexity of the prosthetic leg you need.
- Below-the-Knee / Transtibial: This only requires a section with the ankle, foot, and ankle. These are relatively simple.
- Above-the-Knee / Transfemoral: This is a bit more complicated because it requires the addition of a functional knee joint .
The knee joint is a very important part of our body when we walk. It is this joint that bears the weight of the body and maintains balance. Also, whether we can run, ride a bike, or swim or not depends on the functioning of this knee joint.
The higher the level of leg removal, the more complicated it becomes to attach the artificial leg to the body.
Mechanical and Bionic Legs
The joints in a prosthetic leg can be mechanical or bionic. Bionics are joints that contain computer microprocessors. These can automatically adjust to the type of terrain you are walking on (e.g., a hill, stairs).
| Artificial leg type | Description and advantages/disadvantages |
|---|---|
| Mechanical legs | These work with simple mechanisms like springs and gears. They are very strong, durable, lightweight , and inexpensive. But they are not "smart". They are suitable for normal walking and sitting. |
| Bionic legs | Because they have microprocessors, they get real-time data about your movements and adjust accordingly. They adapt to different activities and environments, just like a natural leg . They're more expensive. |
What are the main parts of a prosthetic leg?
A prosthetic leg is a combination of several parts. When designing the right leg for you, your prosthetist will talk to you about each of these parts.
- Socket: This is the cup-like part that connects the prosthetic leg to the residual limb. This is custom-made to your exact measurements. You may need to take several measurements to get it just right.
- Suspension System: The system that holds the socket in place on the leg. There are various methods for this, such as straps, belts, and suction/vacuum methods.
- Skeleton: This is the "bone" part of the prosthetic leg. The part that connects the socket and the joint. This usually looks like a metal tube.
- Joints: An above-the-knee prosthesis requires a knee joint. These can be mechanical or bionic.
- Foot: The foot that is attached to the end of the artificial leg. This also comes in different types. Some feet are designed for specific activities, such as swimming or running.
How does the process of getting a prosthetic leg work?
This is not something that happens overnight. It is a journey that takes time, patience, and a lot of practice. It can feel overwhelming at times. That's why it's important to manage expectations.
Here are the steps on this journey:
1. Medical consultation and assessment: First, your doctor will examine you, discuss your physical fitness, lifestyle, and goals, and help you decide which prosthetic leg is best for you.
2. Fitting: The prosthetist will then take measurements of your leg, possibly even a 3D scan, and begin making the socket.
3. Basic training: Once your prosthetic leg is made, you will be taught how to wear it, take it off, clean it, and maintain it.
4. Physical Therapy: This is the most important part. A physical therapist will work with you to strengthen your muscles. You will gradually learn how to walk, sit, and climb stairs using the prosthetic leg. This training period can last from a few months to a year.
5. Mental health support: As you train physically, you also need to adjust mentally to this new experience. This is a big mental change. Therefore, it is very important to seek help from a mental health counselor or peer support groups of people who have had similar experiences.
Problems and issues that may arise
It is not normal to feel pain when using a prosthetic leg. If this happens, tell your doctor or prosthetist immediately . It could be a loose socket or a skin allergy.
Other obstacles that may arise:
- Skin injuries or pressure sores can occur because the socket is not in place.
- Skin infections due to excessive sweating inside the socket.
- Pain at the site of the amputation, or phantom limb pain , is the feeling of having a missing limb.
- Having to repair or replace parts due to mechanical defects.
Many of these risks can be avoided with accurate measurements, good training, and proper maintenance.
Will I need a wheelchair with a prosthetic leg?
For some people, yes. It depends on your overall health and your mobility goals. Some people may only use their prosthetic leg for limited activities, such as walking short distances around the house. Others may only use it to help with things like transferring from a wheelchair to a vehicle.
This doesn't mean you're a failure. A prosthetic leg is a device that's meant to make your life easier . Your success can't be measured by how long you use it or what you use it for.
Take-Home Message
- A prosthetic leg is a valuable tool that can bring mobility and independence back into your life.
- This journey takes time, patience, and practice. Never skip physical therapy.
- Talk openly with your doctor and prosthetic specialist to choose the prosthetic leg that best suits you.
- If you experience pain, discomfort, or skin problems while using your prosthetic leg, do not ignore it and seek medical advice immediately.
- Mental health is just as important as physical health. Don't hesitate to seek mental health support if needed.
