Background: Thoracolumbar fractures sometimes require anterior support and post-traumatic deformity correction. SpineJack proved favorable results in cadaveric and clinical studies, with satisfactory pain relief, vertebral height restoration, and low rates of above adjacent fractures, in neurologically intact fractures. We compared patients' clinical and radiological outcomes of thoracolumbar fractures treated either with posterior arthrodesis or SpineJack. Methods: We prospectively collected A2 split and A3, and A4 burst fractures between 2017 and 2021. Patients were stratified in posterior arthrodesis (PA group) and SpineJack (SJ group) and included if age ≥18 years, T11-L3 level, emergent or elective surgery, single or multiple, and neurologically intact. Age, sex, type and level, pain, operative and discharge time, vertebral body heights (VBH), posterior wall retropulsion (PWR), vertebral kyphosis (VK) and local kyphosis (LK) angles, vertebral body (VB) volume, and complications were collected. We then compared clinical-radiographic outcomes between the two groups. Results: We found no significant differences in median postoperative pain while operative time and discharge time were shorter for SJ patients than PA ones (P<0.001). Mean anterior VBH increase was 20.7%, mid-VBH was 25.5%, and posterior VBH was 8.8%, while increase in VB volume was 26.2%. SJ patients had non-inferior VK e LK angles correction to PA ones. Mean PWR value between pre and post SJ implantation was 0.15±0.65 mm, and no adjacent above-level fractures occurred. Conclusions: We showed satisfactory outcomes in a selected range of neurologically intact thoracolumbar split or burst fractures. SJ leads to shorter operative and discharge time and good VB angles and diameters restoration. 2022 Journal of Spine Surgery. All rights reserved.
