AB - Study Design:Prospective controlled cohort studyObjective:To analyze the clinical outcome of video-assisted thoracoscopic surgery (VATS) between two different types ofimplants.Summary of Literature Review:The problem of correction loss has been reported with VATS, and different screws and rodshave been developed to overcome this problem. Different implants will have varying effects in correctional outcome afterVATS. Materials and Methods:A total of 39 cases of idiopathic adolescent scoliosis treated with VATS between June 2001 and Janu-ary 2005 were included in the study (mono-axial screws and a 4.5 mm rod: thin rod group=19 cases; poly-axial reductionscrews and a 5.5 mm diameter rod: thick rod group=20 cases). All patients were followed for over 2 years postoperatively. Forthe comparison of surgical outcomes between the two groups, radiographic measurements were performed in the coronal andsagittal planes. Results:Preoperative scoliosis angle (thin rod group 49.8。, thick rod group 47.1。), age, BMI, Risser stage, union time, operativetime, and blood loss showed no statistical difference between the two groups. Postoperative average correction rate of scoliosisangle was 69% (15.8。) in the thin rod group and 70% (14.1。) in the thick rod group. However, correction rate after 2 years was51% (24.5。) in the thin rod group and 60% (18.7。) in the thick rod group, showing statistically significant difference. There wasa tendency toward correction loss in the thin rod group (8.7。vs. 4.6。p=0.0057). Conclusion:Postoperative correction rate was satisfactory in both groups. However, the thin rod group showed substantial cor-rection loss. Therefore, poly-axial screws and thick rods are more suitable in VATS correction of scoliosis.
