Sagittal atlantoaxial joint inclination and reduction index values for diagnosis and treatment of irreducible atlantoaxial Dislocation

Conclusions: SAAJI and RI can be used as important imaging indicators to determine the reversibility of IAAD. If the RI value is >27.9% and SAAJI value is <32.5°, reduction and fixation can be achieved by the posterior approach alone; otherwise, a combination of anterior and posterior approaches would be necessary.
