Abstract

Background: Atlantoaxial instability is mainly caused by trauma. C2 nerve is usually needed to be sacrificed for adequate exposure of the lateral mass and screw insertion. Objectives: This study aimed to investigate the clinical outcome of postoperative complications of C1 and C2 screw-rod fixation using the Goel-Harms technique for C1-C2 instability after sacrificing the C2 nerve root. Methods: Amongst forty patients with C1-C2 pathology, twenty-seven cases were enrolled into the study, then variables, including age, sex, primary pathology, operation duration, postoperative pain, paresthesia, anesthesia, and other specific conditions, were documented. Data analyzed by an expert biostatistician. p-value < 0.05 was considered significant. Results: Regardless of gender, the most postoperative adverse effect was occipital anesthesia (81.5%). Most of the patients (63%) had both occipital pain and anesthesia one-month post-surgery. At 3- and 6-months post-surgery, occipital pain and anesthesia were seen in 40.7% and 14.8%, respectively. Conclusion: The most common postoperative adverse effect of C2 nerve root scarification after C1-C2 fixation is occipital anesthesia followed by occipital paresthesia and pain, which are reduced in severity over time. © 2021 Elsevier Ltd
