Abstract Background Treatment of congenital hemivertebra is challenging and data on long-term follow-up (≥ 5 years) are lacking. This study evaluated the surgical outcomes of posterior thoracolumbar hemivertebra resection and short-segment fusion with pedicle screw fixation for treatment of congenital scoliosis with over 5-year follow-up. Methods This study evaluated 27 consecutive patients with congenital scoliosis who underwent posterior thoracolumbar hemivertebra resection and short-segment fusion from January 2007 to January 2015. Segmental scoliosis, total main scoliosis, compensatory cranial curve, compensatory caudal curve, trunk shift, shoulder balance, segmental kyphosis, and sagittal balance were measured on radiographs. Radiographic outcomes and all intraoperative and postoperative complications were recorded. Results The segmental main curve was 40.35° preoperatively, 11.94° postoperatively, and 13.24° at final follow-up, with an average correction of 65.9%. The total main curve was 43.39° preoperatively, 14.13° postoperatively, and 16.06° at final follow-up, with an average correction of 60.2%. The caudal and cranial compensatory curves were corrected from 15.78° and 13.21° to 3.57° and 6.83° postoperatively and 4.38° and 7.65° at final follow-up, with an average correction of 69.2% and 30.3%, respectively. The segmental kyphosis was corrected from 34.30° to 15.88° postoperatively and 15.12° at final follow-up, with an average correction of 61.9%. A significant correction (p < 0.001) in segmental scoliosis, total main curve, caudal compensatory curves and segmental kyphosis was observed from preoperative to the final follow-up. The correction in the compensatory cranial curve was significant between preoperative and postoperative and 2-year follow-up (p < 0.001), but a statistically significant difference was not observed between the preoperative and final follow-up (p > 0.001). There were two implant migrations, two postoperative curve progressions, five cases of proximal junctional kyphosis, and four cases of adding-on phenomena. Conclusion Posterior thoracolumbar hemivertebra resection after short-segment fusion with pedicle screw fixation in congenital scoliosis is a safe and effective method for treatment and can achieve rigid fixation and deformity correction.

Introduction: Blood loss with spinal surgery is common potential cause of morbidity and often requires blood transfusion. Tranexamic acid (TXA), is effective in reducing bleeding in patients undergoing knee arthroplasty. TXA used in spine surgery studies have included different cases leading to inconsistence of surgical procedures. Purpose of this prospective observational study was to examine effect of TXA decreasing bleeding in short segment pedicle screw fixation for thoracolumbar fractures. Methods: 38 patients' undergoing short segment pedicle screw for thoracolumbar fractures were enrolled in study from July to August 2013. There were 28 male and 10 female patients, with an average age of 36.5 years. Patients received 10 mg/kg of TXA or a control 30 minutes intravenously before skin incision and 3 hours post-operative and oral medication for three days. Intraoperative bleeding was estimated by weighing surgical sponges, blood collected by suction container and by subtracting all irrigation fluid. Postoperative bleeding was measured from volume in vacuum drainage bag. Results: Twenty (20) patients were in control group and eighteen(18) to TXA group. There were no statistical differences between groups in terms of age, gender, co-morbidities, and operating time, preoperative Hemoglobin, PT and INR. Intra-operative bleeding in TXA group was significant than in control group. Post-operative drainage and Hemoglobin in first 48 h was reduced compared with placebo in TXA group. Need for post-operative transfusion was nil in TXA group. Conclusions: Administration of TXA before surgery significantly reduces perioperative bleeding in patients undergoing short segment pedicle screw fixation for thoracolumbar spine fractures.  Keywords: bleeding; spinal surgery; tranexamic acid.
