Cervical spine consists of 7 bones from C1 to C7. C1 and C2 are called atypical cervical vertebrae. Stable fracture: Vertebral components will not be displaced by normal physiological loads after injury Unstable fracture: Vertebral components will displace further d/t serious disruption of the structures jeopardizing the spinal cord The function of Disk: Binds vertebrae […]
