Cemented femoral impaction bone grafting for severe osteolysis in revision hip arthroplasty. Good results at 4-year follow-up of 10 patients.

Ten hips underwent impaction bone grafting with cement as revision of the femoral stem for severe osteolysis. At clinical follow-up of a median of 4 years (range 3.0-4.6 years) there were no failures. The median Harris hip score increased from 53 to 80, and pain score from 25 to 40. Radiographically, there was no resorption of the impacted grafts. All of the 9 patients with radiographical follow-up of more than 1 year showed trabecular remodelling, 7 of whom had signs of cortical repair. Subsidence was a median of 2 mm, with the maximum subsidence being 5 mm. The results appeared clinically stable after 4 years with radiographic reconstitution of the bone stock.
