Objective:To investigate the efficacy of closed reduction anterior ring subcutaneous internal fixation stent(INFIX)on the treatment of anterior pelvic ring fracture.Methods:82 patients with pelvic anterior ring fractures from January 2019 to January 2023 were selected.The patients were divided into observation group(44 cases)and control group(38 cases)according to different surgical methods.The observation group underwent closed reduction and INFIX internal fixation,while the control group underwent percutaneous plate internal fixation.The general conditions of the sur-gery,fracture reduction efficacy,postoperative recovery,postoperative Majeed score and functional prognosis,inflammatory factors(C-reactive protein(CRP),interleukin-6(IL-6),tumor necrosis factor-α(TNF-α)),and complications were com-pared between the two groups.Results:The intraoperative blood loss in observation group were lower than those in control group,and the operative time was shorter than that in control group(P＜0.05).There were no significant differences in fracture reduction rate,fracture healing time,partial weight bearing time and full weight bearing time between observation group and control group(P＞0.05).The sexual life and sitting scores of observation group were lower than those of con-trol group 3 months after operation(P＜0.05).The good and good rates of functional prognosis in the observation group were 86.36％and 93.18％at 3 months and 6 months after surgery,compared with 89.47％and 92.11％in the control group(P＞0.05).CRP,IL-6 and TNF-α in observation group were lower than those in control group 3 d and 7 d after surgery(P＜0.05).There was no significant difference in the incidence of complications between the observation group 2.27％(1/44)and the control group 5.26％(2/38)(P＞0.05).Conclusion:Closed reduction INFIX internal fixation and percutaneous plate internal fixation are safe and relia-ble treatment options for patients with anterior pelvic ring fractures,but the former can shorten the operation time,reduce the amount of blood loss,alleviate inflammation and improve the early sex life of patients.
