Which term describes an externally applied device used to support and align a limb?

• A. Brace
• B. Splint
• C. Orthotic Device
• D. Cast

Answer: (C)

Externally applied devices that support and align a limb are called orthotic devices (orthoses). Orthoses are designed to hold joints in the correct position, support function, and guide movement, either to prevent deformity or to aid healing and daily activities. They can be rigid or flexible, and may be custom-made or prefabricated. A brace or a splint is a type of orthotic device, but the broader term best fits the description of an externally applied apparatus used to support and align a limb. A cast, while also applied externally, is mainly for immobilization during healing rather than ongoing support and alignment, so it’s not the best fit for this description.
