- Abstract: BACKGROUND:With the increasing attention of scholars at home and abroad to children's cervical spine-related diseases,the demand for exploring the anatomical indicators and changes of cervical spine morphology and development in children of different ages is increasing.OBJECTIVE:To explore and analyze the morphological changes of children with different ages and vertebral sequences by measuring the anatomical position indexes of C2-C7 neurocentral synchondrosis in children aged 1-6 years.METHODS:Normal cervical spine CT images were retrospectively collected from 160 children aged 1-6 years at provincial tertiary hospitals.They were divided into six groups according to an age group of 1 year.The raw data of consecutively scanned cervical spine tomography images were imported into Mimics 16.0 software.The positional anatomical indexes of cervical spine segments C2-C7 in coronal and transverse planes were measured and analyzed under the two-dimensional image window by choosing the measurement tools under the toolbar of Measurements.RESULTS AND CONCLUSION:(1)The distance between the two sides of C2-C7 neurocentral synchondrosis and the distance between the left and right sides of neurocentral synchondrosis and the transverse process gradually increased with age.The overall development of vertebrae in each cervical vertebral segment was faster than the ossification of the neurocentral synchondrosis.(2)The cross-sectional angles on both sides of C2-C7 neurocentral synchondrosis gradually increased with age,and the angles between the left and right sides of neurocentral synchondrosis and the anterior and posterior edges of the vertebral body gradually decreased.Both sides of the neurocentral synchondrosis in cervical vertebral segments tended to grow toward the arch site,which mainly promoted the growth and development of the arch.(3)Except for C7,the angle between the coronal planes on both sides of the cervical spine changed little with the descending neurocentral synchondrosis of the cervical spine,and the neurocentral synchondrosis of the cervical spine was more inclined to longitudinal growth and ossification.(4)The neurocentral synchondrosis position changes in C7 were significantly different from those in the rest of the cervical vertebrae.(5)The anatomical indexes of C2-C7 neurocentral synchondrosis position in children have obvious development rules among different ages and vertebral bodies,and these rules are helpful for the clinical diagnosis and treatment of cervical spine diseases in children.
