Abstract: Objective　To explore the clinical effects and advantages of femoral intertrochanteric fracture treated by wire bound cemented bipolar femoral head replacement and sliding hip screw internal fixation.　Methods　 80 cases of patients with femoral intertrochanteric fracture were included in our study. All the patients were  divided into the following two groups according to the surgical method: 42 cases in an experiment group and 38 cases in a control group, which were treated wire bound cemented bipolar femoral head replacement and sliding hip screw internal fixation, respectively. Some parameters such as surgical time, intraoperative blood loss, bed time, VAS score, Harris functional score and complications were evaluated. Results　The surgical time, intraoperative and postoperative blood loss of the experimental group were higher than those of the control group, there was statistical difference between the two groups (P<0.05). The bed time of the experimental group was shorter than that of the control group, there was significant difference between the two groups (P<0.05). The VAS score and Harris score of patients in the experimental group during the follow-up at 6 months and 12 months were better than those of  the control group. There was statistical difference in the complication rate, the VAS score and Harris score between two groups(P＜0.05). The complication rate of the experimental group and the control group were 28.6% and 63.2%  (χ2=9.13，P=0.003).    Conclusions    Compared with dynamic sliding hip screw internal fixation, wire bound cemented bipolar femoral head replacement has intraoperative trauma, but short bed time, thus can be carried out early functional exercises, which has better clinical effect and is worthy of clinical promotion.
