Summary
Evidence from five randomized controlled trials suggests that treatment of proximal femoral fractures with unipolar versus bipolar hemiarthroplasty (HA) leads to comparable results with respect to functional outcomes, short and long-term mortality, and risk of dislocation and infection. Only one study had a follow-up rate of 85% or greater. Low rates of follow-up lead to possible selection bias. Additional methodologically rigorous randomized controlled trials with higher follow-up rates are necessary to establish the long-term safety and to compare the efficacy of these two operative treatments.
