Objective The correlation analysis was proceeded between youth cervical hook and transverse foramen by using imaging scanning and three-dimensional reconstruction method,which can provide theoretical basis for early diagnosis,treatment and prevention of ju-venile cervical spondylosis.Methods A total of 66 teenagers who had no trauma,neurological symptoms or signs were selected with aged from 6 to 20 years old,who were scanned by multi slice spiral CT,ranged from C1 to T1 .The original data in DICOMformat to import 3D re-construction software was related index measurement and subsequent statistical analysis.Results There was a correlation between hook height,base width,base length of luschca joint and transverse diameter,longitudinal diameter.Conclusion Hook vertebral meridian of lus-chca joint and transverse foramen has a close contact.Factors such as fracture and hyperplasia of luschca joint,vertebral artery of transverseforamen can be oppressed that cause corresponding vertebral artery type of cervical spondylosis.

BACKGROUND:With the change of modern living habits, the incidence of cervical disease and cervical related diseases is increasingly at younger age. Based on this feature, the discussion of the relationship between the cervical spine and vertebral body as wel as regular feature can provide theoretical basis for early diagnosis, prevention and treatment of cervical spondylosis. OBJECTIVE:To analyze the correlation structure of the cervical vertebra uncinate process with the vertebral body and intervertebral foramen among adolescents. METHODS:A total of 66 cases without injuries, neurological symptoms or signs of 6 to 20 years old were scanned with multi-row thin-slice spiral CT from C1-T1. The original data were loaded in DICOM format into three-dimensional reconstruction software for measurement and statistical analysis. RESULTS AND CONCLUSION:(1) In addition to uncinate process height and vertebral body height, the uncinate process spacing, uncinate base width and diameter between the vertebrae and a uncinate process base radius vector length and vertebral bodies were positively correlated (P<0.05). (2) Uncinate high uncinate base long uncinate base width and height between the foramen in addition to the uncinate process had a positive correlation with the length of the substrate (P<0.05). (3) In conclusion, there is a certain correlation in juvenile cervical uncovertebral joint between the uncinate process and vertebral body and intervertebral foramen. With the growth of age, cervical activity is increased and the uncinate hyperplasia, trauma, and fracture can oppress spinal nerve within the intervertebral foramen to cause corresponding nerve root type of cervical spondylosis.

BACKGROUND:As a unique structure of the cervical spine,the occurrence,development and progression of the uncovertebral joint directly affect the stability and range of motion of the cervical spine,and are also closely related to the pathogenesis of cervical spondylosis.A thorough understanding of the developmental characteristics of the uncovertebral joint is of great significance for the pathogenesis,diagnosis,and treatment of cervical spondylosis. OBJECTIVE:By using imaging and three-dimensional reconstruction technology to measure and observe the cervical uncinate process-related angle in a large sample of different age groups,the aim is to reveal the characteristics of its changes with age and vertebral growth,as well as its relationship with cervical spine stability. METHODS:Using a retrospective research design,we collected 1 447 cases of raw CT imaging data that meet the study requirements for complete cervical spine segments.The raw data were imported into Mimics 21.0 software in DICOM format for post-processing and measurement of angle of uncinate process and sagittal angle of uncinate process.The data were grouped based on gender,age,and side. RESULTS AND CONCLUSION:(1)With the increase of vertebral sequence,the angle of uncinate process increased in a V-shaped shape,and the lowest peak was at C5.The overall population showed a sharp peak with the increase of age,and the peak value mostly occurred in the age range of 30-39 years.(2)The sagittal angle of the uncinate process increased like a fishhook with the increase of the vertebral sequence,and the overall angle of the uncinate process increased with age,and the peak value mostly occurred in the age range of 20-29 years.The uncinate process angle and sagittal angle showed only partial significant differences between sides and genders(P<0.05).(3)It is concluded that the angle of the uncinate process increased with the increase of vertebral sequence in a V-shaped manner.The sagittal angle of the uncinate process increases like a fish hook with increasing vertebral order,while the two angles generally peak with increasing age.The angle of the uncinate process is about 131°,which may be closely related to the stability of the cervical spine,while the sagittal angle of the uncinate process is about 14°,and its function may play a certain role in limiting the excessive rotation of the cervical spine.
