Abstract: Objective　 To investigate the development and application values of  hollow malleable lead wire in the treatment of intertrochanteric fractures. 　Methods　From August 2016 to May 2018, 84 patients with intertrochanteric fractures treated surgically in our hospital were enrolled and divided equally into a study group and a control group  according to the method of random number table. In the control group, the fractured block was fixed with a traditional thread during surgery, while in the study group the fractured block was fixed by the self-made hollow malleable lead wire. The intraoperative and postoperative related indicators of the two groups were recorded and compared.　Results　There were no statistical difference in the length of surgical incisions, surgical duration, volume of intraoperative blood loss, times of X-ray exposure and volume postoperative drainage between the two groups (P>0.05). The postoperative hospitalization length was shorter, and the time for fracture union and total weight-bearing was earlier in the study group than in the control group( P＜0.05). Excellent and good rate of hip function 6 months after surgery was higher in the study group (97.6%) than in the control group (78.6%)(P<0.05). Incidences of complication including lower extremity venous thrombosis, pulmonary infection, hip varus, incision infection, and loosening of the fixation was 4.8% 6 months after surgery, lower than 6.2% in the observation group (P<0.05).　Conclusion　The development and application of hollow malleable surgical lead wire in the treatment of intertrochanteric fractures can promote the rehabilitation of patients, improve hip function and reduce postoperative complications.
