Gibaud Ortho C3 rigid cervical collar, size 1, provides relative immobilization of the cervical spine for mild cervical trauma, minor-to-moderate cervical injuries and cervicobrachial neuralgia. The device is adjustable in height by coupling two rigid parts and secures posteriorly with hook-and-loop fasteners. Made of polyethylene with vinyl protective fabric, it is supplied ready to use in a single-piece pack. First fitting should be performed by a qualified specialist; choose size by neck circumference and position the lower part on the clavicles and the upper part under the chin to prevent forward flexion. Clean with a damp sponge.
