Study on the curative effect of operational treatment on the ankle joint fracture in supination-external rotation type

Objective:To explore the curative effect of operation on the ankle joint fracture in supination-external rotation type(S-E-R type).Methods:Eighty-two cases with ankle joint fracture in S-E-R type were processed with operation from January 2006 to September 2010.The ankle joint functions were compared between the diseased side and the healthy side at the 6th and the 12th months after the operation respectively,The ankle joint functions at the 6th months after the operation were compared with that at the 12th months after the operation.Results:Six months after the operation,the ankle joint function of diseased side was worse than that of the healthy side,and there was statistical difference between them(t=-8.286,P=0.000).Twelve months after the operation,the ankle joint function of diseased side was close to that of the healthy side,and there was no statistical difference between them(t=1.179,P=0.240).Ankle joint function of diseased side at the 12th months after the operation was improved a lot compared with that at the 6th months after the operation,and there was statistical difference between them(t=-10.769,P=0.000);and the same situation also occurred in the healthy side(t=-6.819,P=0.000).Conclusion:It can improve the curative effects of operation on ankle joint fracture in S-E-R type and effectively recover the ankle joint functions through the following methods as accurate evaluation of the injuries,proper operation opportunity and fixation methods,the recovery of the complete articular surface and the stable ankle joints,effective functional exercises after the operation.
