title: Clinical outcome of cemented bipolar hemiarthoplasty versus Austin Moore hemiarthroplasty for displaced intracapsular fractures of hip in terms of anterior thigh pain in elderly.
abstract: OBJECTIVE
  To explore a less pain-inciting implant in terms of anterior thigh pain after hip hemi-arthroplasty in displaced intra-capsular fractures of the neck of femur.
  
  
  METHODS
  The cross-sectional comparative study was conducted at the Combined Military Hospital, Rawalpindi, from November 2013 to June 2014, and comprised patients of either genders with age above 55 years and having displaced intra-capsular fractures of the neck of femur. The patients were divided into two equal groups, with Group A patients undergoing Austin Moore hemi-arthoplasty and Group B having cemented bipolar hemi-arthoplasty. Follow-up was done at 4, 8 and 12 weeks postoperatively for anterior thigh pain on the basis of visual analogue scale. Mean pain scores for both groups were calculated and compared.
  
  
  RESULTS
  There were 60 patients; 30(50%) in each group. The mean age in Group A was 78.40±6.95 years, while in Group B it was 77.16±6.32. The overall male-to-female ratio was 1.8:1. All patients had uneventful postoperative recovery. Mean anterior thigh pain in Group A was statistically higher than Group B (p<0.05).
  
  
  CONCLUSIONS
  Compared to Austin Moore hemi-arthoplasty, cemented bipolar hemi-arthoplasty caused significantly lower incidence of anterior thigh pain.
