Comparison of total hip arthroplasty and hemiarthroplasty in elderly patients with femoral neck fracture

Objective: To compare total hip arthroplasty and hemiarthroplasty in elderly patients with femoral neck fracture. Methods: 100 cases of elderly patients with femoral neck fractures enrolled in our hospital from October 17, 2015 to March 17, 2017 were selected and divided into 2 groups (Group A and Group B) randomly with 50 patients in each group. Patients in Group A were treated with total hip arthroplasty while those in Group B received hemiarthroplasty. The intraoperative conditions (time and amount of bleeding) and postoperative status (out-of-bed activity and complications) of patients in each group were compared and the treatment effect was analyzed. Results: In Group A, the operation time lasted 89.26 ± 10.05 min, the amount of intraoperative bleeding was 402.61 ± 31.16 ml and the patients began to get out of bed in 7.15 ± 1.29 d. In Group B, the operation time was 68.49 ± 9.76 min, 218.26 ± 28.43 ml intraoperative bleeding and 5.31 ± 1.47 d was taken to get up from the bed. The differences of those indexes between two groups were significant (P<0.05). However, there was no significant difference in the complications and treatment effects (P>0.05). Conclusion: Hemiarthroplasty and total hip arthroplasty have different effect on the treatment of elder patients with femoral neck fractures, thus making it necessary to determine the surgical plan according to the patient’s situation.
