title: Systematic review of cemented versus uncemented hemiarthroplasty for displaced femoral neck fractures in older patients.
abstract: The purpose of this review was to assess the effectiveness and safety of cemented versus uncemented hemiarthroplasty for displaced femoral neck fractures in older patients. We searched the Cochrane Library, MEDLINE and EMBASE for published randomized clinical trials comparing cemented with uncemented hemiarthroplasty for femoral neck fractures. Eight trials assessing 1,175 hips were eligible for meta-analysis. The pooled results showed that there was no significant difference between cemented and uncemented group with regard to the mortality, reoperation rates and postoperational complications. The overall incidence of residual pain at 1 year after operation was 23.6% in the cemented prosthesis and 34.4% in the uncemented, with significant difference (relative risk 0.69, 95% CI 0.53-0.90; P = 0.007; fixed-effect models).The available evidence suggested that compared with uncemented hemiarthroplasty, cemented hemiarthroplasty in treating the elderly with displaced femoral neck fractures was not associated with a higher risk of mortality, reoperation and complications but can reduce the risk of residual pain and provide better functional results.
