To measure the zygapophyseal joints anatomic parameters of the lower cervical spines in adults by picture archiving and communication system (PACS) and explore its clinical significance.
Sixty-three adults were included in this study, all of whom received CT examination on the cervical spine, and the relative data of cervical zygapophyseal joints were transmitted manually to PACS.Then in AquariusNET Viewer (V220.127.116.11) the parameters were measured manually.Statistical analysis was carried out subsequently, then the mean and standard deviation were calculated and compared between both sides and between male and female subjects.
No statistical differences were found in transverse, sagittal and oblique diameter respectively between both sides of cervical zygapophyseal joints in adults.Bilateral zygapophyseal joints of the lower cervical spine in adults are symmetrical on the whole.The sagittal diameter was about 11-13 mm, and oblique diameter 11-12 mm in male adults, while 10-12 and 10-11 mm respectively in female ones.Zygapophyseal joints in the male were bigger than those in the female.
Measurement of the zygapophyseal joints anatomic parameters of the lower cervical spines in adults by PACS have high consistency, and it has reference value for the selection of the lateral mass screws in the posterior cervical fusion surgery.According to the Magerl or Anderson technique for the insertion of lateral mass screws, the length of 12-14 mm is safe for the male, and 12 mm for the female.
