title: Acetabular reconstruction using a free fibular autograft in total hip arthroplasty revisions.
abstract: OBJECTIVE
  Acetabular reconstruction for segmentary bone loss aims for primary stability and long-lasting integration. The use of a fibular autograft has been described after tumour resection and in traumatology. The hypothesis of this study is that it offers a mechanically reliable solution with good functional results and acceptable morbidity.
  
  
  METHODS
  This is a two center retrospective study of 26 operated hips. Indication was mechanical loosening in every case. The operative technique included fibular grafting of a segmental bone loss associated with an acetabular metal reinforcement.
  
  
  RESULTS
  Mean follow up was 88 months (three to 165). The PMA score increased from 8.5 (five to 12) to 15 (six to 18) (p <0.001). Acetabular migration was 2 mm (0-4) vertically and 1 mm (0-2) medially. Three graft failures were observed. No major morbidity was observed.
  
  
  CONCLUSIONS
  Fibular autograft after mechanical loosening and segmentary bone loss in total hip arthroplasty revisions offers a mechanically reliable solution for acetabular reconstruction. The results seem to be at least equivalent to other techniques.
