First described by A. Cooper and later classified by G. Jefferson, atlas fractures are the incidental result of falls and other trauma that result in hyperextension, or axial compression of the C1 vertebra. 1–3. Today, isolated fractures of the C1 vertebrae represent up to 11% of all cervical fractures in adults.
Is a Jefferson fracture serious?
Though a serious injury, the long-term consequences of a Jefferson’s fracture are uncertain and may not impact longevity or abilities, even if untreated. Conservative treatment with an immobilization device can produce excellent long-term recovery.
How serious is a C1 neck fracture?
C1 and C2 Vertebrae Breaks, Fractures, and Misalignments Due to the high level and placing of these vertebrae at the top of the neck, having a C2 or C1 vertebrae out of place or suffering sustained damage is most often fatal (or leaves the individual fully paralyzed).
Can you break your atlas?
The atlas is subject to fracture under axial load, often due to traumatic injuries such as shallow dives and automobile accidents. These fractures account for 2–13 % of injuries to the cervical spine [Marcon RM et al.
Can you survive a hangman’s fracture?
Although a hangman’s fracture is unstable, survival from this fracture is relatively common, as the fracture itself tends to expand the spinal canal at the C2 level. It is not unusual for patients to walk in for treatment and have such a fracture discovered on X-rays.
Why is it called a hangman’s fracture?
The hangman’s fracture refers to a break in a bone known as C2, because it is the second bone down from the skull in your cervical (neck) vertebrae.
What does C1 atlas do?
The atlas (plural: atlases) is the first cervical vertebra, commonly called C1. It is an atypical cervical vertebra with unique features. It articulates with the dens of the axis and the occiput, respectively allowing rotation of the head, and flexion, extension and lateral flexion of the head.
Can you survive a C1 and C2 fracture?
Injuries to the C1 and C2 vertebrae are rare, accounting for only 2% of spinal injuries each year. However, they are also considered to be the worst spinal cord injury that it is possible to sustain, and often fatal.
Why is it called Undertaker fracture?
Undertaker’s fracture is an artifact related to poor handling of the corpse characterized by subluxation of the lower cervical spine from tearing of the intervertebral disc at C6-C7 vertebral level. It occurs due to sudden fall of the head over occipital region.
Why is it called chauffeur’s fracture?
The name originates from early chauffeurs, who sustained these injuries when the car back-fired while the chauffeur was hand-cranking to start the car. The back-fire forced the crank backward into the chauffeur’s palm and produced the characteristic styloid fracture.
