A device used to support or correct the position of a limb or the spine, often in the form of a brace.
The doctor recommended an orthosis to help support her injured ankle.
Orthosis → It is formed from "orthos" (from Greek, meaning straight or correct) and "-sis" (a suffix used in medical terminology to denote a process or condition). The word "orthosis" refers to the process of correcting or straightening a part of the body, typically through the use of a supportive device.
Think of 'straight' or 'correct' ('orthos') to remember that 'orthosis' is about a process that helps to correct or support a part of the body.
