Prostheses are artificial devices designed to replace missing body parts, such as limbs, teeth, or organs. They are used to restore function, improve appearance, and enhance the quality of life for individuals with disabilities or congenital conditions. Prostheses can be categorized into two main types: external and internal.

External prostheses are worn on the surface of the body and include upper limb prostheses, lower limb prostheses, and orthotic devices. Upper limb prostheses can be further divided into hand prostheses, forearm prostheses, and elbow prostheses, depending on the level of amputation. Lower limb prostheses include knee prostheses, ankle-foot prostheses, and transfemoral prostheses. Orthotic devices, such as braces and splints, are used to correct deformities, improve mobility, and prevent further damage.

Internal prostheses, also known as bionic devices, are implanted within the body to replace missing organs or tissues. Examples include cardiac pacemakers, which regulate the heart's rhythm, and cochlear implants, which restore hearing in individuals with severe hearing loss. Internal prostheses are typically controlled by external devices or wirelessly, allowing for greater flexibility and functionality.

Prostheses are typically custom-made to fit the individual's body and lifestyle, and they can be made from a variety of materials, including metals, plastics, and carbon fiber. Advances in technology have led to the development of more advanced and sophisticated prostheses, such as myoelectric prostheses, which use electrical signals from the muscles to control the device, and bionic limbs, which incorporate sensors and actuators to mimic the natural movement of the human body.

Prostheses play a crucial role in the lives of individuals with disabilities, providing them with the opportunity to participate in daily activities, pursue education and employment, and lead fulfilling lives. However, the cost of prostheses can be a significant barrier to access, and ongoing research and development are needed to improve the affordability and functionality of these devices.
