Background: Maintaining balanced sagittal balance after lumbar fusion surgery results in reducing muscular effort to maintain the upright position. This will improve the outcome of back pain post-operatively. Aim of Study: This study aims to determine the outcome of back pain when maintaining postoperative sagittal balance. Patients and Methods: The sagittal balance was calculated for patients undergoing lumbar fusion surgeries. Disability in-dices were calculated for the patients postoperatively to deter-mine the outcome of back pain. The outcome of surgery is then correlated with the postoperative results of the sagittal balance. Results: There was statistically significant correlation be-tween the outcome of fusion surgery and maintaining a balanced postoperative sagittal balance. The mean lumbar lordosis angle was the main determinant of the postoperative sagittal balance value. The 3 months VAS score postoperative was significantly better when postoperative pelvic harmony is achieved. Conclusion: Post operative sagittal balance was maintained when the lumbar lordosis angle was maintained postoperative-ly. Better outcome of back pain was associated with maintain-ing a balanced sagittal balance post operatively.
