The optimal surgical approach is a matter of debate and may include anterior, posterior or a combined anteroposterior (360\u00ba) approach. Analyzing a cohort of patients initially treated with anterior cervical discectomy and fusion (ACDF) for traumatic subaxial injuries, the study aimed to identify predictors for treatment failure and the subsequent need for supplementary posterior fusion (PF).<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Methods<\/jats:title>\n                <jats:p>A retrospective, single center, consecutive cohort study of all adult patients undergoing primary ACDF for traumatic subaxial cervical spine fractures between 2006 and 2018 was undertaken and 341 patients were included.

A delayed supplementary PF was performed in 11 cases, due to ACDF failure. On univariable regression analysis, older age (<jats:italic>p<\/jats:italic>\u2009=\u20090.017), shorter stature (<jats:italic>p<\/jats:italic>\u2009=\u20090.031), posterior longitudinal ligament (PLL) injury (<jats:italic>p<\/jats:italic>\u2009=\u20090.004), injury to ligamentum flavum (<jats:italic>p<\/jats:italic>\u2009=\u20090.005), bilateral facet joint dislocation (<jats:italic>p<\/jats:italic>\u2009&lt;\u20090.001) and traumatic cervical spondylolisthesis (<jats:italic>p<\/jats:italic>\u2009=\u20090.003) predicted ACDF failure.
