To investigate the clinical effect of total hip arthroplasty in the treatment of femoral neck fracture in elderly patients.

165 cases of elderly patients with femoral neck fracture in our hospital from January 2014 to August 2016 were chosen as experimental subjects, and were divided into control group and research group with the random number table. The control group was treated with internal fixation of hollow screw, and the research group was treated with total hip arthroplasty. After the treatment, clinical operation index, hip function, and complications between the two groups were compared.

The operation time and hospital stay of the research group were longer than those of the control group [(1.38±0.51)h vs.(0.87±0.28)h, (17.42±1.67)d vs.(11.06±1.54)d], intraoperative bleeding was more than that of the control group [(365.05±22.31)ml vs.(131.40±13.58)ml], with statistically different differences (P<0.05). The excellent and good rate of hip function improvement of the research group was 90.36%, which was higher than that of the control group (64.63%), with statistically different difference (P<0.05). There were 5 cases (6.02%) of complications in the research group and 24 cases (29.27%) in the control group, with statistically different difference (P<0.05).

Compared with internal fixation of hollow screw, total hip arthroplasty is more traumatic in the treatment of femoral neck fracture in elderly patients, but has better improvement in hip function, and lower complication rate.
