protézisnek

A protézis is a medical device designed to replace a missing body part. These artificial devices can be used to restore function, appearance, or both. The need for a prosthesis can arise from congenital conditions, trauma, disease, or surgical amputation. Prosthetic devices are custom-made to fit the individual, considering factors such as size, shape, and desired function.

Prostheses can be broadly categorized into external and internal types. External prostheses, such as artificial limbs, are worn on the outside of the body. These can range from relatively simple cosmetic replacements to highly sophisticated devices incorporating advanced technology for movement and sensation. Internal prostheses, also known as implants, are surgically placed within the body. Examples include artificial joints (like hip or knee replacements), dental implants, and pacemakers.

The development and use of prosthetics have a long history, with early examples dating back to ancient civilizations. Modern prosthetics benefit from advancements in materials science, biomechanics, and computer-aided design and manufacturing, leading to increasingly lifelike and functional replacements for lost body parts. The goal of prosthetic rehabilitation is to help individuals regain independence and improve their quality of life.
