title: Revision total hip arthroplasty with femoral impaction bone grafting.
abstract: OBJECTIVE
  To report the radiological and clinical results of revision total hip arthroplasty (THA) with femoral impaction bone grafting (IBG).
  
  
  METHODS
  4 men and 9 women (15 hips) aged 38 to 84 years underwent revision THA with femoral IBG using Elite plus stems for aseptic loosening or infection.
  
  
  RESULTS
  The mean follow-up duration was 7.7 years. The Harris hip score improved from 61.7 to 83.7. There was no pain in 11 hips and slight pain in 4. The mean subsidence was 5.7 mm. The mean change of alignment was 1.2 degrees. There was no radiological evidence of stem loosening. One stem was revised due to a peri-prosthetic fracture. Cortical healing was noted in 11 hips, and trabecular incorporation in 10.
  
  
  CONCLUSIONS
  Although intra- and post-operative complications were not uncommon, femoral IBG is a safe procedure in carefully selected patients and offers good medium-term results.
