AB  - Background Nonoperative management is an appealing option for purely transosseous thoracolumbar flexion-distraction injuries given the prospects of osseous healing and restoration of the posterior tension band complex. This study seeks to examine differences in outcomes following flexion-distraction injuries after operative and nonoperative management.Methods This study reviews all patients at a single Level 1 trauma center from 2004 to 2022 with AO Spine B1 thoracolumbar injuries treated operatively vs nonoperatively. Inclusion criteria were age greater than 16 years, computed tomography-confirmed transosseous flexion-distraction injuries, and at least 3 months of follow-up with available imaging. The primary outcome assessed was a change in local Cobb angles, with secondary outcomes consisting of complications, time to return to work, and need for subsequent operative fixation.Results Initial Cobb angles in the operative (n = 14) vs nonoperative group (n = 13) were −5° and −13°, respectively (P = 0.225), indicating kyphotic alignment in both cohorts. We noted a significant difference in Cobb angles between cohorts at first follow-up (2.6° and −13.9°, P = 0.015) and within the operative cohort from presentation to first follow-up (P = 0.029). At the second follow-up, there was no significant difference in Cobb angles between cohorts (3.6° and −12.6°, P = 0.07). No significant differences were noted in complication rates (P = 1), time to return to work (P = 0.193), or resolution of subjective back pain (P = 0.193). No crossover was noted.Conclusions Nonoperative management of minimally displaced transosseous flexion-distraction injuries is a safe alternative to surgery. Patient factors, such as compliance with follow-up, and location of the injury should be factored into the surgeon’s management recommendation.Clinical Relevance Overall, no significant differences in outcomes and complications were noted following nonoperative management of AO Spine B1 injuries, indicating the potential for these injuries to be managed conservatively.Level of Evidence 3.
