@donasmrs-- What kind of injury are you referring to?
Different body braces are needed for different injuries. It depends on where the injury is and what type of support is needed. If there are multiple injuries affecting the spine, as well as the legs for example, there are comprehensive full body braces. These are often used in hospitals or in home care after serious accidents such as a fall or a car accident.
If the injury is in the back, such as a compression fracture, something like a Jewett brace may be used.
