Brace therapy may be the treatment a patient needs in order to heal correctly. The brace will help stabilize and immobilize the spine in the area where surgery was performed. Usually, braces are categorized as being soft, flexible, rigid, and semi-rigid. Flexible braces are pre-made in different sizes, so the doctor may make simple adjustments for the proper fit. For the other brace, the doctor will measure the specific part of the body to create a custom cast. The adjustability of a brace depends on the purpose of the brace.
