Abstract：Objective To explore the application effect of different methods of modified Nuss bar fixation for non-thoracoscopic-assisted pectus excavatum(PE)surgery.Methods A retrospective analysis was conducted on the clinical data of 53 patients who underwent PE surgery by using modified Nuss bar in Department of Thoracic Surgery,Xiangya Hospital of Central South University from July 2021 to December 2023.According to whether or not steel wire fixation was used and the fixation methods,the patients were divided into non-steel wire fixation group(11 patients),unilateral fixation group(15 patients),and bilateral fixation group(21 patients),excluding 5 patients with 2 steel bars fixed and 1 patient with steel wire bridge.The overall condition of the patients was analyzed and the clinical data were compared among the three groups.Results Among the 53 patients,45 patients were male and 8 patients were female,with a median age of 15 years and a median Haller index of 3.86.Steel wire fixation was not used in11 patients(20.75%),and unilateral steel wire fixation was used in 15 patients(28.30%),and bilateral steel wire fixation in27 patients(50.94%).The median follow-up time was 17 months.Fifty-one patients had a follow-up period of 1 year,and 15 patients had a follow-up period of 2 years.The incidence of postoperative complications was28.30%,and the proportions of the patients who were satisfied with the orthopedic treatment outcomes at 1 month,1 year and 2 years after surgery were 92.45%,90.20%and80.00%,respectively.There were statistically significant differences in the preoperative Haller index and operation duration among the three groups(P＜0.05),and the operation duration of the non-steel wire fixation group was significantly shorter than that of the bilateral fixation group(P＜0.05).There were no statistically significant differences in the postoperative pain scores,Haller indexes at 1 month and 1 year after surgery,length of hospital stay after surgery,postoperative complications and the proportion of the patients who were satisfied with the orthopedic treatment outcomes at 1 year after surgery among the three groups(P＞0.05).Conclusion The modified Nuss bar fixation has a certain orthopedic effect.The non-wire fixation method is potentially feasible for non-thoracoscopic-assisted PE surgery.
