Cervical spine fractures

Cervical spine fractures can occur secondary to exaggerated flexion or extension, or because of direct trauma or axial loading.

Pathology

The cervical spine is susceptible to injury because it is highly mobile with relatively small vertebral bodies and supports the head which is both heavy and acts as a lever. Fulcrum of movement is different in children than adults, C2/3 compared to C5/6, respectively; hence, in children cervical fractures are more common in upper vertebrae.

There are also other anatomical differences of the cervical spine between children and adults which worth bear in mind while interpreting paediatric studies. These include more horizontal orientation of the facet joints in children, underdeveloped uncal joints, mild physiological anterior wedging of the vertebral bodies, and incomplete ossification of odontoid process.

There are many types of cervical spine fracture, some of which are unstable; general indicators of instability include:

Some fractures are associated with blunt cerebrovascular injury (BCVI) such as high (C1-C3) fractures, those associated with subluxation and of course, those fractures involving the transverse foramen.

Mechanism

The four major mechanisms are flexion, extension, rotational and shearing, each associated with certain fracture patterns 3,4
