Publication Risk Factors for Failure of Non-operative Management in Isolated Unilateral Non-displaced Facet Fractures of the Subaxial Cervical Spine: Systematic Review and Meta-Analysis(2024) Cirillo, Ignacio; Ricciardi, Alejandro; Cabrera, Juan Pablo; López Muñoz, Felipe; Romero Vlverde, Lyanne; Joaquim, Andrei; Carazzo, Charles; Yurac, RatkoStudy Design: systematic review.Objective: To evaluate risk factors associated with failure of non-operative management of isolated unilateral facet fractures ofthe subaxial cervical spine in neurologically intact patients.Methods: A systematic review of the PubMed, Embase, LILACS, and Cochrane Library databases was conducted in order todetermine risk factors associated with failure of non-operative management in isolated unilateral facet fractures of the subaxialcervical spine without facet and/or vertebral displacement, in neurologically intact patients. Our research was in line with thePRISMA Statement and registered on PROSPERO (CRD42023405699).Results: A total of 1639 studies were identified through a database search on May 5, 2023. In total, 7 studies from the databaseswere included, along with 1 study found through a manual citation search. The evidence showed high clinical heterogeneity, aserious risk of bias according to the ROBINS-I tool, and a predominance of retrospective cohort studies. In comparison to lesscomplex facet fractures, lateral floating mass fractures were found to have 5.41 times higher odds of failure of non-operativemanagement (OR = 5.41; 95% CI = 1.32, 22.19). We calculated the potential association between lower absolute fracture heightand non-operative treatment success [Fracture height (percentage) Mean Difference = 17.51 ( 28.22, 6.79 95% CI); Absolute height Mean Difference: 0.46 ( 0.60, 0.31 95% CI)]. Other risk factors were not included in the meta-analysis dueto lack of data. The level of certainty was rated as “very low”.Conclusions: Lateral floating mass cervical facet fractures and larger fracture fragment size (measured either in absolute termsor as a percentage) are significant risk factors for failure of non-operative treatment.
