〔Abstract〕 Objective To investigate the effect of artificial femoral head replacement on hip function and complications in elderly patients with intertrochanteric femoral fracture (IFF). Methods Sixty IFF patients admitted to the Third Affiliated Hospital of Henan University of Traditional Chinese Medicine from May 2020 to May 2022 were selected and randomly divided into an observation group and a control group, with 30 cases in each group.The control group was treated with locking proximal femoral plate (LPFP), and the observation group was treated with artificial femoral head replacement. The incidence of complications between the two groups was observed, and the bone mineral density, visual analogue scales (VAS) and Harris hip function score of patients before and after surgery were compared. Results 1 month after surgery, bone mineral density in the two groups was higher than that before surgery , and bone mineral density in the observation group was higher than that in the control group, the difference was statistically significant (P < 0.05). The VAS score of the observation group was lower than that of the control group, and the Harris score was higher than that of the control group, the differences were statistically significant (P < 0.05). The incidence of complications in the observation group was lower than that of the control group, and the difference was statistically significant (P < 0.05). Conclusion Artificial femoral head replacement is an ideal operation in IFF patients, which can restore the hip function of patients with low risk of postoperative complications.
