“…Some researches have shown that during traumatic and nontraumatic accidents the fractures or dislocation of vertebrae or damage of soft tissue including the spinal cord was usually found at C4–C8 level [ 28 , 29 , 31 , 33 , 36 , 37 ] and low intervertebral disc levels were more exposed to damage because of their size [ 38 ].
