A prosthetic is an artificial device designed to replace a missing body part, such as a limb or a breast. These devices help individuals regain functionality and improve their quality of life. Prosthetics can be custom-made to fit the user's body and can vary in complexity, from simple wooden legs to advanced robotic limbs that respond to muscle signals. Prosthetics are often used by people who have lost limbs due to injury, illness, or congenital conditions. Advances in technology, such as 3D printing and robotics, have led to more effective and comfortable prosthetic options, enhancing mobility and independence for users.
