Impaired mobility of the upper cervical spine in children and adolescents

The article is based on the analysis of 185 cases of impaired mobility of the upper cervical spine. A classification of instability and hypomobility of the craniovertebral segment according to the etiological characteristic, mechanism, and severity of mobility impairment has been proposed. Clinical manifestations of instability and hypomobility are described. Clear criteria for diagnostics have been developed using functional radiography of the cervical spine and functional computed tomography of the C1 - C2 and CO - C1 segments. The state of blood circulation in the system of vertebral arteries was studied in this pathology. The indications for surgical and conservative treatment have been clarified.
