Objective To measure the X-ray related parameters of lower cervical vertebral body in elderly patients with Kashin-beck disease (KBD), so as to clarify the influence of KBD on the development of lower cervical vertebral body. Methods Sixty-two patients with KBD (KBD group) and sixty-seven healthy people (control group) were treated with lateral cervical radiographs to observe the imaging manifestations of the lower cervical vertebral body. The anterior, middle and posterior heights of the vertebral body and anterior-posterior diameters from C3 to C7 in neutral position were measured and statistical analysis was performed. Results The results of this study showed that the superior and inferior margins of the vertebral endplate were uneven, depressed and sclerosis in some KBD patients. The heights of anterior and posterior margins of vertebral body were higher than that of the middle margin, and there was no significant difference between the height of anterior and posterior margins (P>0.05). In the KBD group, the median heights of C4-6 in males and C4-7 in females were smaller than that of anterior and posterior margin, and the difference was statistically significant (P<0.05). The median heights of C4-7 in males and C3-7 in females in the control group were higher than that in the KBD group, with statistically significant difference(P<0.05). There were significant differences in anterior-posterior diameters between male and female groups in the KBD patients (P<0.05). The anterior -posterior diameters of males and females in the control group were larger than those in the KBD group, but there was no statistical difference (P>0.05). Conclusions KBD can cause the depression, uneven and sclerosis of endplate cartilage, lead to the reduction of the middle height of cervical vertebral body, but do not affect the development of anterior -posterior diameters of the vertebral body.
