Abstract:
ObjectiveTo investigate the relationship between the imaging manifestations and postoperative efficacy scores through measuring postoperative ankle mortise morphometry of Rüedi-Allg(o)wer Ⅲ pilon fracture.MethodsForty-seven cases of Rüedi-Allg(o)wer Ⅲ pilon fracture patients,including 20 males and 27 females with a mean of 43 years (range,21-65 years) were treated and followed up.Indexes including the width,height,depth,coronal angle and sagittal angle of ankle mortise were measured at the last follow-up.According to the Mazur score at the last follow-up,operated ankle functions were evaluated and divide into three groups (excellent group,good group and poor group.By comparing the five indexes of 47 cases and 3 groups between injury ankle and healthy ankle,we analyzed the correlation of the ankle mortise change and the ankle function.ResultsAll patients were followed up 18-24 months(mean,21 months).The results showed there were significant differences about all the measuring indexes except the height of ankle mortise between the injury ankle and healthy ankle of 47 follow-up cases.About the difference between both sides in 3 groups,the results showed there was a negative correlation between all indexes except the height of ankle mortise and the Mazur score.No correlation was found between the height of ankle mortise and the Mazur score.Recovering the ankle mortise's width,depth,coronal angle as well as sagittal anglein the surgery of severe pilon fractures has a significant effect on ankle function.ConclusionRecovery of the ankle mortise's width,depth,coronal angle as welld as sagittal angle during the surgery of severe pilon fractures has a significant effect on ankle function,so the anatomy of the ankle mortise should be recovered as much as possible.
