Cervical Orthosis
Pronunciation: SER-vi-kul or-THOH-sis
An external device applied to the neck to immobilise, limit, or support cervical spine motion following injury, surgery, or in the management of cervical pathology.
Full Definition
A cervical orthosis (CO) encompasses a spectrum of devices ranging from soft foam collars, which provide minimal restriction, to rigid two-poster or four-poster braces that significantly limit flexion, extension, and rotation. Editors must be aware that 'cervical collar' is an acceptable lay synonym in patient-facing materials but should not replace 'cervical orthosis' in clinical or professional documents. The abbreviation CO should be defined on first use, as it may be confused with 'contracture orthosis' in some clinical contexts. Cervical orthoses are categorised separately from cervico-thoracic orthoses (CTO), which extend to the thorax for additional immobilisation.
Usage
Usage note: Prefer 'cervical orthosis' over 'cervical collar' in clinical writing. Do not abbreviate to CO without first defining it, particularly in documents where other abbreviations using 'C' are present.
