Study Design: Retrospective observational. Objectives: This study aimed to document the safety and efficacy of lumbar corpectomy with reconstruction of anterior column through posterior-only approach in complete burst fractures. Methods: In this retrospective study, we analyzed complete lumbar burst fractures treated with corpectomy through posterior only approach between 2014 and 2018. Clinical and intraoperative data including pre and post-operative neurology as per the ISNCSCI grade, VAS score, operative time, blood loss and radiological parameters, including pre and post-surgery kyphosis, height loss and canal compromise was assessed. Results: A total of 45 patients, with a mean age of 38.89 and a TLICS score 5 or more were analyzed. Preoperative VAS was 7-10. Mean operating time was 219.56 ± 30.15 minutes. Mean blood loss was 1280 ± 224.21 ml. 23 patients underwent short segment fixation and 22 underwent long segment fixation. There was no deterioration in post-operative neurological status in any patient. At follow-up, the VAS score was in the range of 1-3. The difference in preoperative kyphosis and immediate post-operative deformity correction, preoperative loss of height in vertebra and immediate post-operative correction in height were significant (p < 0.05). Conclusion: The posterior-only approach is safe, efficient, and provides rigid posterior stabilization, 360° neural decompression, and anterior reconstruction without the need for the anterior approach and its possible approach-related morbidity. We achieved good results with an all posterior approach in 45 patients of lumbar burst fracture (LBF) which is the largest series of this nature.
