Abstract：Objective To compare the clinical efficacy of suture button titanium plate and single cortical screw in the treatment of lower tibiofibular syndesmosis injury of ankle fractures.Methods From January 2020 to January 2022,the clinical data of patients with ankle fracture with lower syndesmosis injury in our hospital were collected.According to different fixation methods of syndesmosis,the patients were divided into suture button titanium plate group and single cortical bone screw group.There were 28 cases in the suture button titanium plate group(group A)and 33 cases in the single cortical screw group(group B).The early,mid and long term functional results,lower tibiofibular combined imaging changes,operation time,hospital stay and complications were compared between the two groups,and the risk factors affecting early ankle function were analyzed.Results The ankle motion score of group A(17.2±1.2)was higher than that of group B(15.8±2.3)one month after surgery,and the differences were statistically significant(P=0.005).The AOFAS score of group A was higher than that of group B[91(80-98)vs.80(68-87)]3 months after operation,and the differences were statistically significant(P=0.003).There was no significant difference in AOFAS scores between the two groups at 6 months and 12 months after surgery(P>0.05).At 1 and 3 months after surgery,there was no significant difference between the two groups in the lower tibiofibular space and lower tibiofibular overlap distance(P>0.05).There was no significant difference in operation time,hospital stay and complications between the two groups(P>0.05).Screw fixation was an independent risk factor for ankle motion<15 points 1 month after surgery(P=0.011)and ankle AOFAS score<90 points 3 months after surgery(P=0.032).Conclusions Locking loop titanium plate is as safe and effective as single cortical screw in the treatment of lower tibiofibular syndesmosis injury of ankle fracture.The early functional results of locking loop titanium plate are better than screw fixation,and the medium and long term results are similar.Screw fixation is an independent risk factor affecting the early functional results.
