Fixator is a term commonly used in medicine to refer to a device that helps to stabilize or immobilize a body part during injury, surgery, or healing. Synonyms for fixator include orthosis, splint, brace, immobilizer, supporter, and stabilizer. Orthosis refers to a device that helps to correct or improve the function of a body part, while a splint is a device that supports and immobilizes a body part to promote healing. An immobilizer and a brace also provide support and stabilization, but an immobilizer typically restricts movement more than a brace. A supporter provides additional support to a body part during movement, while a stabilizer helps to reduce movement and stabilize the affected area.
