Abstract: Objective To investigate the effect of orthopedic distractor assisted reduction and percutaneous plate implantation in the treatment of distal tibial fractures.Methods 120 patients with distal tibial fractures treated in Wendeng orthopedic hospital of Shandong Province from January 2019 to January 2021 were randomly divided into two groups:the control group (60 cases,percutaneous plate implantation and internal fixation under traditional manual reduction) and the observation group (60 cases,orthopedic distractor assisted manual reduction and percutaneous plate implantation and internal fixation).The treatment effect,intraoperative indexes and postoperative fracture recovery of the two groups were compared,and the complications of the two groups were recorded and compared.Results After treatment,there was no significant difference in the excellent and good rate of fracture healing in the observation group (P>0.05);The operation time[（72.56±27.54）min] and fracture healing time[（16.45±4.59）w] of the observation group were shorter than those of the control group[（89.94±28.20）min and（21.15±4.54）w],and the amount of intraoperative bleeding in the observation group[（82.27±20.14）ml] was less than that of the control group[（90.12±21.48）ml],the differences were statistically significant (P<0.05);12 months after operation,the knee joint score of American Special Surgery Hospital (HSS) and ankle hindfoot score of American ankle Orthopedic Association (AOFAS) in the observation group[（85.24±7.52） and （84.58±7.29）] were lower than those in the control group [（74.45±7.64） and （74.56±6.38）](P<0.05).There was no significant difference in the total incidence of complications between the two groups (P>0.05).Conclusion Orthopedic distractor assisted reduction and percutaneous steel plate implantation and internal fixation have good curative effect,which can effectively reduce the amount of intraoperative bleeding,shorten the operation time,and have a good recovery of foot and ankle function after operation.
