摘　　要：Purpose:To assess the relationship between dislocation and functional outcomes in supination-external rotation(SER)ankle fractures.Methods:A retrospective case series study was performed on patients with ankle fractures treated surgically at a large trauma center from January 2015 to December 2021.The inclusion criteria were young and middle-aged patients of 18 e 65 years with SER ankle fractures that can be classified by Lauge-Hansen classification and underwent surgery at our trauma center.Exclusion criteria were serious life-threatening diseases,open fractures,fractures delayed for more than 3 weeks,fracture sites2,etc.Then patients were divided into dislocation and no-dislocation groups.Patient demographics,injury characteristics,surgery-related outcomes,and postoperative functional outcomes were collected and analyzed.The functional outcomes of SER ankle fractures were assessed postoperatively at 1-year faceto-face follow-up using the foot and ankle outcome score(FAOS)and American Orthopedic Foot and Ankle Society ankle hindfoot score and by 2 experienced orthopedic physicians.Relevant data were analyzed using SPSS version 22.0 by Chi-square or t-test.Results:During the study period,there were 371 ankle fractures.Among them,190(51.2%)were SER patterns with 69(36.3%)combined with dislocations.Compared with the no-dislocation group,the dislocation group showed no statistically significant differences in gender,age composition,fracture type,diabetes,or smoking history,preoperative waiting time,operation time,and length of hospital stay(all p>0.05),but a significantly higher Lauge-Hansen injury grade(p<0.001)and syndesmotic screw fixation rate(p=0.033).Moreover,the functional recovery was poorer,revealing a significantly lower FAOS in the sport/rec scale(p<0.001).Subgroup analysis showed that among SER IV ankle fracture patients,FAOS was much lower in pain(p=0.042)and sport/rec scales(p<0.001)for those with dislocations.American Orthopedic Foot and Ankle Society ankle hindfoot score revealed no significant diffe
