To compare clinical characteristics, patients were divided into two groups based on the presence of postoperative complications: a complication group (14 cases) and a control group (47 cases). Logistic regression analysis was then used to identify factors associated with postoperative complications.Results: Disease duration, fever status, and hemoglobin levels differed significantly between groups (all P < 0.05). Further, multivariate analysis identified diabetes, fever, and psoas muscle abscess as independent risk factors for postoperative complications (all P < 0.05).Conclusion: Having diabetes, fever, and psoas muscle abscess are independent risk factors for complications after a one-stage posterior approach for thoracolumbar Brucellosis spondylitis. Therefore, careful selection of surgical indications, strict surgical technique, proper blood glucose management in diabetic patients, and preoperative control of body temperature are essential to reduce complication rates.Keywords: thoracolumbar spine, brucellosis spondylitis, postoperative complications, risk factors
