Cemented versus cementless hemiarthroplasty for a displaced fracture of the femoral neck: a systematic review and meta-analysis of current generation hip stems.

Our aim was to prepare a systematic review and meta-analysis to compare the outcomes of cemented and cementless hemiarthroplasty of the hip, in elderly patients with a fracture of the femoral neck, to investigate the mortality, complications, length of stay in hospital, blood loss, operating time and functional results.
