A case is presented of an 18-year-old athlete with fibrous dysplasia of the femoral neck and head. The approach was by joint plastic and orthopaedic teams, which minimized operating time and allowed the option of vascular bone grafting. The lesion was curetted through a greater trochanteric window and the defect reconstructed with a free vascularized fibula graft with excellent result. Weight bearing was achieved in six months and there was minimal donor site morbidity. We believe the free vascularized fibula graft to be a reconstructive option, in difficult orthopaedic problems, facilitated by microsurgery and there is immense benefit of a joint effort between the orthopaedic and plastic surgical teams.
