Posterior atlantoaxial transpedicular screw and plate fixation - Technical note

The authors describe a modified posterior atlantoaxial fixation technique for the treatment of reducible atlantoaxial instability, which can be performed simply and easily, and can decrease the risk of vessel and/or neural damage. During an 18-month period, this technique was undertaken in 11 patients with atlantoaxial instability. There was no procedure-related morbidity. The follow-up period ranged from 8 to 18 months (mean 13.2 months). Fusion was documented in all I 1 patients, and there was no progression of spinal deformity. This technique can be considered an effective alternative in the treatment of atlantoaxial subluxation.
