Abstract：Objective To compare the efficacy of inverted"pin"shaped cannulated screws and dynamic hip screw(DHS)combined with cannulated screw internal fixation in the treatment of Garden type Ⅲ femoral neck fracture in middle-aged and young patients.Methods Ninety-eight middle-aged and young patients with femoral neck fracture of Garden type Ⅲ admitted from January 2015 to December 2019 were selected as the study objects.Patients were divided into cannulated screw group(n=46)and DHS group(n=52)according to different internal fixation methods.All patients were followed up for at least 9 months to evaluate the results within perioperative indexes,postoperative healing and functional scores.Results The operation time of cannulated screw group was significantly lower than that of DHS group,while the duration of fluoroscopy time was significantly higher than that of DHS group,and the differences were statistically significant(P<0.05).The intraoperative blood loss and hospital stay in cannulated screw group were lower than those in DHS group,and the differences were statistically significant(P<0.05).The femoral neck shortness post-operation in cannulated screw group was higher than that in DHS group,and the difference was statistically significant(P<0.05).But there was no significant difference in fracture healing time and Harris hip score between the two groups(P>0.05).Conclusion Both internal fixation methods exerted optimal clinical effects.Internal fixation with inverted"pin"shaped cannulated screws has the advantages of less intraoperative bleeding and short operation time.DHS combined with cannulated screw fixation has better reduction effect and less intraoperative fluoroscopy.
