Halo traction

A halo-vest is used to immobilize and protect the cervical spine and neck after surgery or accident. The halo is a ring that surrounds the head and is attached by pins to the outer portion of the skull. It is used to stabilise the cervical spine, or to correct its alignment (Rationale 1, Rationale 2).

Halo vest traction is used infrequently for child and young people (CYP). It is usually a planned event, and in children is fitted under a general anaesthetic.
