Total hip arthroplasty resulted in significantly better hip function compared to bipolar hemiarthroplasty at 48 months (mean Harris hip score 89 vs 75, p<0.001).
RCT (n=120)
Does total hip arthroplasty improve hip function and quality of life compared to bipolar hemiarthroplasty in elderly patients with displaced femoral neck fractures?
Total hip arthroplasty provides better long-term hip function and quality of life than bipolar hemiarthroplasty in elderly patients with displaced femoral neck fractures.
Absolute Event Rate: 89% vs 75%
p-value: p=< 0.001
We performed a four-year follow-up of a randomized controlled trial involving 120 elderly patients with an acute displaced femoral neck fracture who were randomized to treatment with either a bipolar hemiarthroplasty or a total hip arthroplasty. The difference in hip function (as indicated by the Harris hip score) in favor of the total hip arthroplasty group that was previously reported at one year persisted and seemed to increase with time (mean score, 87 compared with 78 at twenty-four months p < 0.001 and 89 compared with 75 at forty-eight months p < 0.001). The health-related quality of life (as indicated by the EuroQol EQ-5D(index) score) was better in the total hip arthroplasty group at the time of each follow-up, but the difference was significant only at forty-eight months (p < 0.039). These results confirm the better results in terms of hip function and quality of life after total hip arthroplasty as compared with hemiarthroplasty in elderly, lucid patients with a displaced fracture of the femoral neck.
Hedbeck et al. (Wed,) conducted a rct in Acute displaced femoral neck fracture (n=120). Total hip arthroplasty vs. Bipolar hemiarthroplasty was evaluated on Hip function (Harris hip score) at 48 months (p=< 0.001). Total hip arthroplasty resulted in significantly better hip function compared to bipolar hemiarthroplasty at 48 months (mean Harris hip score 89 vs 75, p<0.001).
