Abstract
BackgroundThe purpose of this review was to assess the risk of infection-related complications following cemented and cementless hemiarthroplasty in elderly patients.MethodsWe searched PubMed, EMBASE, and Cochrane Library databases for published randomized clinical trials comparing cemented hemiarthroplasty with cementless hemiarthroplasty in patients with a femoral neck fracture and more than 65 years of age. Eight randomized controlled trials were available for analysis. A meta-analysis (with a fixed-effects model) and a meta-regression analysis (with continuous variables) were performed.ResultsThe 8 trials included 1,204 hips (608 cemented and 596 cementless). There was no significant difference between the cemented and cementless groups regarding the incidence of deep infection, superficial infection, pneumonia, and urinary tract infection. The overall incidence of postoperative deep infection was 2.3% (14/608) in the cemented group and 1.2% (7/596) in the cementless group (relative risk, 1.74; 95% confidence interval, 0.74 to 4.14; I2 = 0%; p = 0.206). No publication bias was found in the funnel plot.ConclusionsResults of our meta-analysis suggest that when selecting a fixation method for hemiarthroplasty, infection-related postoperative complications are not the determinant factor to consider.
