Study DesignObservational study on prospectively collected data.ObjectivesTo compare patient-reported outcomes and complications after anteroposterior surgery or anterior surgery in subaxial cervical spine fractures.Summary Of Background DataThere is no consensus regarding the optimal surgical approach for subaxial cervical spine fractures. Although anterior surgery is often sufficient to restore stability, anteroposterior surgery is sometimes preferred in severe instability. The effects of a more extensive procedure on patient-reported outcomes have not been investigated. We hypothesized that patient-reported outcomes and complication rates were similar between these surgical approaches.Materials And MethodsIndividuals treated with either a combined anteroposterior or anterior surgery alone between 2006 and 2016 and with at least 1-year follow-up were identified in the Swedish Spine Registry. Cases were matched 1:2 for age (±5 y). Outcomes were Neck Disability Index (NDI), EQ-5D-3L index, satisfaction, reoperations, and surgeon-reported and patient-reported complications within 90 days. Mann-Whitney U -tests and χ 2 tests were used in statistical comparisons.ResultsThe median [interquartile range] number of instrumented vertebrae was 3 [2-5.5] in the anteroposterior group and 2 [2-3] in the anterior group ( P <0.001). The mean±SD follow-up time was 3.5±2.3 years in the anteroposterior and 3.8±2.0 years in the anterior group ( P =0.39), respectively. At follow-up, Neck Disability Index was 20 [6-37] in the anteroposterior group and 18 [3.5-40] in the anterior group ( P =0.69), and the median EQ-5D-3L index was 0.73 [0.12-0.80] in the anteroposterior group and 0.75 [0.62-0.89] in the anterior group ( P =0.27). Satisfaction with the treatment was reported by 90% in the anteroposterior group and by 87% in the anterior group ( P =0.98). None of the individuals in the anteroposterior and 6 of the individuals in the anterior group were reoperated ( P =0.18).ConclusionPatients operated on with anteroposterior or anterior surgery for subaxial cervical spine fractures are equally satisfied and report similar health-related quality of life measures.Copyright © 2023 Wolters Kluwer Health, Inc.
