In order to discuss the application of bone cement prosthesis stem replacement in the treatment of intertrochanteric comminuted fracture of the femur, the author conducted a previous investigation of clinical and follow-up data. follow-up of two groups of patients with cemented type double femoral head replacement: the normal operation group and the improved operation group, from June 2019 to June In 2021, 40 hospitalized patients with stable intertrochanteric fracture were recruited, including 20 patients who received bipolar artificial femoral head replacement and 20 patients who received get a normal surgery. Operating time, blood loss, hospital stay and Harris hip joint score were recorded 14 days after operation, and postoperative complications, fracture repair and hip function recovery was tracked. Among them, 20 patients were followed for 6 to 15 months, including 11 in the improvement group and 9 in the control group. The results showed that the average working time of the improved group was 24.63 ± 6.97 min shorter than that of the normal working group (p<0.01). The results show that the surgical improvement can reduce the operation time, and then it can reduce the time of injury, reduce the incidence of infection, and reduce the risk of surgery. Compared with the traditional team work, the modified team can reduce the work time and reduce the work risk. There was no difference between the normal and blood-deprived groups, and the post-operative joint function was better than the normal group.
