A<unk>  is a fracture of the anteroinferior aspect of a cervical vertebral body due to<unk>  of the spine along with vertical axial compression. The fracture continues sagittally through the vertebral body, and is associated with deformity of the body and subluxation or dislocation of the facet joints at the injured level. A<unk>  is usually associated with a spinal cord injury, often a result of displacement of the posterior portion of the vertebral body into the spinal canal. The<unk>  should not be confused with a similar-looking vertebral fracture called "extension<unk>  fracture". Both usually occur in the cervical spine, but as their names suggest, they result from different mechanisms<unk> -compression vs. hyperextension). Both are associated with a small fragment being broken apart from the anteroinferior corner of the affected vertebra.<unk> s usually involve instability in all elements of the spine at the injured level, commonly occur at the C4-C7 vertebra, and have a high association with spinal cord injury (in particular anterior cord syndrome). In comparison, the extension-type fracture occurs more commonly at C2 or C3, causes less if any disruption to the middle and posterior elements, and does not usually result in spinal cord injury (however it may co-occur with more dangerous spine injuries).
