PURPOSE: 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. CONCLUSION: 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.
