Abstract
Introduction We report the results of cancellous femoral impaction grafting with cement in revision hip arthroplasty in all patients from the above centre, who had their surgery more than five years previously.
Methods Up to December 1994, 226 hips underwent femoral impaction grafting in 207 patients. No deaths were attributable to the revision surgery. Thirty-three patients with 35 functioning hips died with less than five years follow-up. Only one patient was lost to follow-up. All other patients have had clinical review by two of the authors (BH and HE) and a combined panel undertook radiological review.
Results Two hips (one percent) became infected at the time of their revision surgery. Twelve stems underwent a further surgical procedure for aseptic failure; 10 for treatment of fracture and two for mechanical loosening in the absence of fracture. Survivorship with any femoral re-operation for any cause as the end point was 90.5% (confidence interval 82 to 98% (Peto equation)) at 10 to 11 years. Using femoral re-operation for symptomatic aseptic mechanical loosening as the endpoint the survivorship was 99.1% (CI= 96–100) at the same follow-up. The technique used in our centre has been modified since this series with an increased use of longer stems with impacted allograft. The technique used in Exeter has evolved and there has been an increased awareness of the fundamental importance of gaining stability of the implant within the graft at the time of surgery.
Conclusion These results provide evidence of a successful technique in the intermediate to long term.
