ortézis

Ortézis, also spelled orthesis, is a medical device designed to support, immobilize, or replace a missing or damaged part of the body. The term originates from the Greek words "orthos" meaning straight or correct, and "hesthai" meaning to stand. Ortézis can be external or internal, and they are used to improve mobility, stability, and function in individuals with various conditions such as fractures, joint replacements, or neurological disorders.

External ortézis are worn on the surface of the body and include devices like braces, splints, and prosthetics. They are used to support and stabilize joints, align bones, or replace missing limbs. For example, a knee brace can help support a damaged knee joint, while a prosthetic leg can replace a missing limb.

Internal ortézis are implanted within the body and include devices like plates, screws, and rods. They are used to stabilize fractures, correct deformities, or replace damaged bones. For example, a plate and screws can be used to stabilize a fractured bone, while a rod can be used to correct a spinal deformity.

Ortézis are typically prescribed by healthcare professionals and are customized to the individual's needs. They can be made from various materials, including metal, plastic, and carbon fiber, and may be adjustable to accommodate changes in the body over time. The use of ortézis can significantly improve quality of life for individuals with mobility or functional limitations, allowing them to perform daily activities with greater ease and independence.
