C2 Screw fixation techniques in atlantoaxial instability: A technical review

Diwakar Shankar, Deepak Kumar Singh, Neha Singh, Rakesh Kumar Singh, Vipin Kumar ChandJournal of Craniovertebral Junction and Spine 2022 13(4):368-377 Atlantoaxial instability (AAI) is surgically a complex entity due to its proximity to vital neurovascular structures. C1-C2 fusion has been an established standard in its treatment for a considerable time now. Here, we have outlined the most common techniques for C2 screw fixation in practice at present such as C2 pedicle, C2 pars, C2 translaminar, C2 subfacetal, C2-C3 transfacetal, and C2 inferior facet screw. We have discussed in detail the technical as well as biomechanical aspects of each technique of C2 screw fixation in AAI and explored the intricacies of each technique.
