Analysis on X-ray measurement of vertebral plate sagittal diameter in developmental cervical canal stenosis / 重庆医学

ABSTRACT

Objective To measure the sagittal diameter of vertebral plate(SDVP) in the developmental cervical stenosis (DCS) group by cervical vertebral lateral X-ray film to provide a new idea for diagnosing DCS.Methods A total of 401 cervical vertebral X-ray films conforming to the standard were collected and divided into the non-DCS group and DCS group.On the lateral radiographs of the cervical spine,SDVP(the distance from the posterior edge of zygapophysial joint to spinal laminar line) at C3-C6 segments was measured,and the differences in SDVP were compared between the non-DCS group and DCS group.Then the differences were also compared between sexes.Results SDVP at C3-C6 segments was(5.23 ± 0.93),(5.55 ± 0.94),(5.64±0.97) and (5.12±0.84) mm in the non-DCS group,and (3.87±1.11),(3.66± 1.00),(3.77±0.92) and (2.99±0.72) mm in the DCS group,the differences between the two groups were statistically significant(P＜0.05),moreover SDVP had the same statistical difference between sexes(P＜0.05).Conclusion SDVP at C3-C6 segments in DCS patients is significant shortened compared with the normal person.
