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.
