As a prosthetics specialist with years of experience in the field, I am well-versed in the various types of prosthetic devices that are available to individuals who have suffered limb loss. These devices are designed to restore function and improve the quality of life for amputees. The different types of prosthetics are primarily categorized based on the level of amputation and the specific part of the body that they are intended to replace. Here's a detailed overview:

1. **Transtibial Prosthesis (Below-Knee Prosthesis)**: This type of prosthesis is designed for individuals who have had an amputation below the knee. It includes a socket that fits over the residual limb, a pylon or knee unit, and a prosthetic foot. The socket is custom-made to fit the shape and size of the residual limb, providing a secure and comfortable fit. The knee unit can be a simple hinge mechanism or a more complex microprocessor-controlled knee that adapts to different walking conditions.

2. **Transfemoral Prosthesis (Above-Knee Prosthesis)**: This prosthesis is for those who have lost a leg above the knee. It consists of a socket that encloses the thigh, a knee joint, and a prosthetic lower leg and foot. The socket is designed to provide stability and support, while the knee joint can vary from a basic mechanical hinge to advanced microprocessor-controlled systems that offer more natural movement and adaptability.

3. **Transradial Prosthesis (Below-Elbow Prosthesis)**: As mentioned in the provided reference, a transradial prosthesis replaces an arm missing below the elbow. It includes a socket that fits over the residual arm, an elbow joint, and a prosthetic hand. The socket is made to accommodate the unique shape of the residual limb, ensuring a secure fit. The elbow joint can be a simple hinge or a more complex system that allows for various degrees of motion.

4. **Transhumeral Prosthesis (Above-Elbow Prosthesis)**: This type of prosthesis is for individuals who have lost an arm above the elbow. It comprises a socket that fits over the upper arm, an elbow joint, and a prosthetic hand. The socket is designed to provide a secure fit and support, while the elbow joint can range from a basic hinge to more sophisticated systems that mimic natural arm movement.


5. Upper Limb Prosthetics: Beyond the transhumeral and transradial prosthetics, there are also various types of upper limb prosthetics that cater to different levels of amputation. These include:
- Shoulder Disarticulation Prosthesis: For those who have lost the entire arm at the shoulder joint.
- Forequarter Amputation Prosthesis: Designed for individuals who have lost the arm along with a portion of the shoulder and chest.
- Terminal Device: A variety of prosthetic hands and hooks are available, each with specific functions to assist with daily activities.


6. Lower Limb Prosthetics: In addition to the transtibial and transfemoral prosthetics, there are also:
- Hip Disarticulation Prosthesis: For those who have lost a leg at the hip joint.
- Hemipelvectomy Prosthesis: Designed for individuals who have undergone a hemipelvectomy, where part of the pelvis and leg are removed.

7.
Cosmetic and Aesthetic Prostheses: These prosthetics are designed to closely resemble the natural limb in appearance. They are often used when functionality is less of a concern and the focus is on improving the individual's self-esteem and body image.

8.
Functional and Rehabilitative Prostheses: These are designed to provide specific functions and aid in the rehabilitation process. They may not look like the natural limb but are highly effective in restoring mobility and independence.

9.
Microprocessor-Controlled Prostheses: These advanced prosthetics use microprocessors to adapt to the user's movements and environment, providing a higher level of functionality and a more natural feel.

10.
Biomechanical and Hybrid Systems: These systems combine mechanical and electronic components to provide a balance between functionality and aesthetics.

Each type of prosthesis is tailored to the individual's specific needs, taking into account factors such as the level of amputation, the individual's lifestyle, and their personal preferences. The field of prosthetics is constantly evolving, with new technologies and materials being developed to improve the functionality and comfort of these devices.

There are four main types of artificial limbs: These include the transtibial, transfemoral, transradial, and transhumeral prostheses. The type of prosthesis depends on what part of the limb is missing.
