This article is from PLoS ONE, volume 9.AbstractBackground: Anterior odontoid screw fixation AOSF has been one of the most popular treatments for odontoid fractures. However, the true efficacy of AOSF remains unclear. In this study, we aimed to provide the pooled rates of non-union, reoperation, infection, and approach related complications after AOSF for odontoid fractures. Methods: We searched studies that discussed complications after AOSF for type II or type III odontoid fractures. A proportion meta-analysis was done and potential sources of heterogeneity were explored by meta-regression analysis. Results: Of 972 references initially identified, 63 were eligible for inclusion. 54 studies provided data regarding non-union. The pooled non-union rate was 10% 95% CI: 7%–3%. 48 citations provided re-operation information with a pooled proportion of 5% 95% CI: 3%–7%. Infection was described in 20 studies with an overall rate of 0.2% 95% CI: 0%–1.2%. The main approach related complication is postoperative dysphagia with a pooled rate of 10% 95% CI: 4%–17%. Proportions for the other approach related complications such as postoperative hoarseness 1.2%, 95% CI: 0%–3.7%, esophageal-retropharyngeal injury 0%, 95% CI: 0%–1.1%, wound hematomas 0.2%, 95% CI: 0%–1.8%, and spinal cord injury 0%, 95% CI: 0%–0.2% were very low. Significant heterogeneities were detected when we combined the rates of non-union, re-operation, and dysphagia. Multivariate meta-regression analysis showed that old age was significantly predictive of non-union. Subgroup comparisons showed significant higher non-union rates in age ≥70 than that in age ≤40 and in age 40 to
