GHILARDI, Cesar Salge et al. Evaluation of different cases with C1-C2 arthrodesis. Coluna/Columna [online]. 2012, vol.11, n.1, pp.70-72. ISSN 1808-1851.

OBJECTIVE: Retrospective record analysis of patients with C1-C2 instability of traumatic and nontraumatic causes who underwent C1-C2 arthrodesis. METHODS: We performed retrospective analysis of medical records of 20 outpatients from the column of IOT-FMUSP aged between 7 and 83 years (mean 43 years) of both sexes. The radiographic parameters for instability were based on measurement of atlanto-axial interval greater than 3 mm in adults and 5 mm in children, using measures obtained from lateral plain X-rays. RESULTS: We operated 20 patients with high cervical instability, mostly due to trauma. The surgical technique used was that described by Magerl. There were no vascular injuries. Infectious complications were reported in two patients. We achieved a solid fusion rate of 85% and no revision surgeries were required. CONCLUSIONS: All techniques produced satisfactory bone healing and were excellent for the control of atlanto-axial instability.
