Abstract: Objective To observe the effects of modified femoral intramedullary nail and dynamic hip screw (DHS) on perioperative indicators,joint function and prognosis in patients with femoral intertrochanteric fracture.Methods A total of 74 patients with femoral intertrochanteric fracture who underwent surgical treatment in the Shangluo Central Hospital from January 2020 to January 2024 were selected and divided into the control group and the observation group according to different treatment methods,with 37 cases in each group.The control group was treated with DHS and the observation group was treated with modified femoral intramedullary nail.The perioperative indicators,joint function,fracture reduction quality and prognosis were compared between the two groups.〖WTHZ〗Results〓〖WTBZ〗The surgical incision length [(5.04±1.07) cm],surgical time [(50.69±10.54) min],intraoperative blood loss [(138.36±20.15) ml],and postoperative drainage volume [(43.16±10.85) ml] in the observation group were significantly lower than those in the control group[（9.58±1.42）cm,（66.71±13.86）min,（251.82±40.62）ml and（100.73±18.46）ml] (P<0.05).Fracture healing time of the two groups was close (P>0.05).At 7 days after surgery,the HHS score of the observation group was significantly higher [(51.58±9.34)score] than that of the control group [(48.3±8.76) score](P<0.05),while there was no significant difference in HHS scores between the two groups before and at 3 and 6 months postoperatively (P>0.05).Comparison of fracture reduction quality between the two groups showed no statistically significant difference (P>0.05).The total incidence of complications in the observation group(10.81%) was significantly lower than that in the control group(29.73%) (P<0.05).〖WTHZ〗Conclusion〓〖WTBZ〗The use of modified femoral intramedullary nails and the application of DHS in the treatment of intertrochanteric fractures of the femur can effectively restore joint function,and the quality of fracture healing and reduction is good.However,the perioperative indicators of modified femoral intramedullary nails are better and the risk of complications is lower.
