Posterior atlantoaxial transpedicular screw and plate fixation

Abstract

✓ 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 11 patients, and there was no progression of spinal deformity. This technique can be considered an effective alternative in the treatment of atlantoaxial subluxation.
