    Study Designsystematic review.ObjectiveTo evaluate risk factors associated with failure of non-operative management of isolated unilateral facet fractures of the subaxial cervical spine in neurologically intact patients.MethodsA systematic review of the PubMed, Embase, LILACS, and Cochrane Library databases was conducted in order to determine risk factors associated with failure of non-operative management in isolated unilateral facet fractures of the subaxial cervical spine without facet and/or vertebral displacement, in neurologically intact patients. Our research was in line with the PRISMA Statement and registered on PROSPERO (CRD42023405699).ResultsA total of 1639 studies were identified through a database search on May 5, 2023. In total, 7 studies from the databases were included, along with 1 study found through a manual citation search. The evidence showed high clinical heterogeneity, a serious risk of bias according to the ROBINS-I tool, and a predominance of retrospective cohort studies. In comparison to less complex facet fractures, lateral floating mass fractures were found to have 5.41 times higher odds of failure of non-operative management (OR = 5.41; 95% CI = 1.32, 22.19). We calculated the potential association between lower absolute fracture height and 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 due to lack of data. The level of certainty was rated as "very low".ConclusionsLateral floating mass cervical facet fractures and larger fracture fragment size (measured either in absolute terms or as a percentage) are significant risk factors for failure of non-operative treatment.

    Transcultural Adaptation and Validation into Spanish of the AO Spine PROST (Patient-Reported Outcome Spine Trauma) Questionnaire
    (SAGE Publishing, 2025) Juan Ignacio Cirillo; Pablo Carreño; Guillermo Alejandro Ricciardi; Ratko Yurac; Gonzalo Kido; Víctor Barrientos; Hugo Vilchis Sámano; Eduardo Laos
    Study DesignMulticenter, cross-sectional study of cross-cultural adaptation and psychometric validation of a patient-reported outcome measure.ObjectiveTo adapt and validate the Spanish version of the AO Spine Patient-Reported Outcome Spine Trauma (PROST) questionnaire for assessing functional outcomes in patients with traumatic spinal injuries.MethodsThe translation followed Beaton's standardized cross-cultural adaptation process: forward translation, synthesis, back-translation, expert committee review, and final version development. Adult patients (≥18 years) with spinal trauma within the last 13 months were recruited from 4 Level 1 trauma centers across Latin America. Exclusion criteria included polytrauma (ISS >15), complete paralysis (ASIA A-B), and cognitive impairment. Participants completed the Spanish PROST and the SF-36. Concurrent validity was evaluated using Spearman's correlation between PROST and SF-36 domains. Internal consistency was assessed via Cronbach's alpha.ResultsA total of 108 patients were included (mean age 46 ± 15.8 years; 57% male). The Spanish PROST showed excellent internal consistency (α > 0.96). It showed a strong correlation with the SF-36 Physical Functioning domain (rs = 0.83; <i>P</i> < 0.0001) and moderate to strong correlations with Vitality, Mental Health, Bodily Pain, and Social Functioning (rs = 0.54-0.64; <i>P</i> < 0.0001). Moderate correlations were also found with Role Physical and Role Emotional.ConclusionThe Spanish AO Spine PROST is a valid, reliable tool for assessing functional outcomes in spinal trauma patients. These findings support its use in both clinical practice and research settings within Spanish-speaking populations.
