Abstract
We searched databases including PubMed Central MEDLINE from 1966 EMBASE from 1980 and the Cochrane Central Register of Controlled Trials database Only prospective randomized controlled trials RCTs that compare bipolar hemiarthroplasty with unipolar hemiarthroplasty for the treatment of femoral neck fracture in the elder patient were included RevMan 52 from the Cochrane Collaboration was applied to perform the metaanalysisSix relevant RCTs with a total of 982 patients were retrieved From this metaanalysis mortality rates showed no statistical difference between two treatments 147 for bipolar versus 138 for unipolar The acetabular erosion rates were significantly different between two groups P = 001 12 in bipolar versus 55 in unipolar group Overall complication rates dislocation rates infection rates and reoperation rates between two groups showed no statistical difference P 005 Neither of two treatments appeared to be superior regarding the clinical function assessed by Harris hip scores or return to preinjury state rates P 005Both bipolar and unipolar hemiarthroplasty for the treatment of elderly patient suffering displaced femoral neck fracture achieve similar and satisfy clinical outcome in shortterm followup Unipolar hemiarthroplasty seems to be a more costeffectiveness option for elderly patient
