title: Hemiarthroplasty vs primary total hip arthroplasty for displaced fractures of the femoral neck in the elderly: a meta-analysis.
abstract: Current updated meta-analysis was designed to compare clinical effects of hemiarthroplasty (HA) vs primary total hip arthroplasty (THA) for displaced femoral neck fractures in elderly patients. Five randomized and 4 quasi-randomized controlled trials with a total 1208 patients were included for final analysis. It showed that mortality and postoperative infection between HA and THA had no statistical differences, that long-term reoperation rate of HA was higher than that of THA, that medium-term dislocation rate of HA was lower than that of THA, and that pain rates of HA in short-term and long-term were both higher than THA. Summarily, treatment of THA for elderly displaced femoral neck fracture could provide better results of reduced reoperation rate and pain relief; however, HA yielded a lower incidence of postoperative dislocation.
