title: Retrospective evaluation of bipolar hip arthroplasty in fractures of the proximal femur.
abstract: BACKGROUND
  There is still controversy about the choice of treatment of displaced fractures of the neck of femur which leads the best clinical and functional outcomes. Treatment options include internal fixation, unipolar or bipolar hemiarthroplasty, or total hip replacement.
  
  
  OBJECTIVE
  The aim of this study is to find out which treatment option can lead to the best clinical and functional outcomes.
  
  
  METHODS
  Fifty one consecutive patients admitted to Makassed General Hospital with a diagnosis of a displaced fracture of the femoral neck during the year 2006 were selected. Preoperative and operative data was retrieved from inpatient hospital files. The patients then were interviewed to fill a questionnaire form. Radiological data was retrieved from inpatient hospital files and outpatient files upon latest follow up visit in clinic. Functional outcomes were assessed with use of Harris hip score. The main clinical measures were mortality and a reoperation.
  
  
  RESULTS
  Postoperatively, Thirty three patients (89.2%) either returned to the functional level that they had had before the fracture or used only a cane, which they had not needed before.
  
  
  CONCLUSIONS
  In our study, the bipolar hemiarthroplasty has served us well. Two-year results of total hip replacement appeared to be better than those of bipolar hemiarthroplasty, but this finding was based on relatively small numbers of patients.
