Novel Technique for C1-2 Interlaminar Arthrodesis Utilizing a Modified Sonntag Loop-Suture Graft With Posterior C1-2 Fixation.

ABSTRACT: OBJECTIVE:Conventional techniques for atlantoaxial fixation and fusion typically pass cables or wires underneath C1 lamina to secure the bone graft between the posterior elements of C1-2, which leads to complications such as cerebrospinal fluid (CSF) leak and neurological injury. With the evolution of fixation hardware, we propose a novel C1-2 fixation technique that avoids the morbidity and complications associated with sublaminar cables and wires. METHODS:This technique entails wedging and anchoring a structural iliac crest graft between C1 and C2 for interlaminar arthrodesis and securing it using a 0-Prolene suture at the time of C1 lateral mass and C2 pars interarticularis screw fixation. RESULTS:We identified 32 patients who underwent surgery for atlantoaxial with our technique. A 60%
