Abstract: ObjectiveTo investigate the effect of double acting total hip arthroplasty in the treatment of traumatic femoral neck fracture.Methods The clinical data of 65 patients with total hip arthroplasty in the Department of orthopedics of Linfen Central Hospital from January 2018 to December 2020 were collected.27 patients with double acting total hip arthroplasty were used as the observation group and 38 patients with traditional total hip arthroplasty were used as the control group,the observation group was treated with double acting total hip arthroplasty,and the control group was treated with traditional total hip arthroplasty.The operation indexes,hip function and activities of daily living,quality of life,range of motion of hip joint and incidence of complications were compared and analyzed between the two groups.Result The improvement of surgical indexes in the observation group was better than that in the control group(P<0.05).The hip function,ADL score and quality of life score of the two groups were increased at 3 and 6 months after treatment.The score in the observation group was higher than that in the control group,and the score at 6 months after treatment was higher than that at 3 months after treatment(P<0.05).There was no significant difference in combined anteversion between the two groups at 6 months after treatment(P>0.05),the activities of internal and external rotation,internal and external exhibition and flexion and extension in the observation group were higher than those in the control group,and the incidence of complications in the observation group was lower than that in the control group(both P<0.05). Conclusion The treatment of traumatic femoral neck fracture with double acting total hip arthroplasty can effectively improve the surgical indexes and hip function,improve the ability of daily life and quality of life,and reduce the incidence of complications.
