Bipolar VS Unipolar Hemiarthroplasty Function in Elderly Hip Fractures

$79 / year

This dataset shows moderate evidence that supports the outcomes of unipolar and bipolar hemiarthroplasty for hip fractures like unstable (displaced) femoral neck fractures are similar.

Complexity

One high strength study (Davison et al 49) and seven moderate strength (Raia et al 74, Cornell et al 75, Jeffcote et al 76, Calder et al 60, Calder et al 77, Hedbeck et al 78, Kenzora et al 79) Kenzora studies compared unipolar and bipolar hemiarthroplasty for the treatment of displaced femoral neck fractures.
All of the included studies showed equivalence in functional and radiographic outcomes, suggesting no significant benefit for bipolar articulation over unipolar hemiarthroplasty for displaced femoral neck fracture. A meta-analysis of mortality at six months and one year show no significant differences between unipolar and bipolar hemiarthroplasty.
