Abstract
Aims: This study reports the results of all patients from our centre who underwent femoral impaction grafting more then five years previously. As a consequence of our experience our technique has been modified and the indications for impaction grafting have become clearer. Methods: 226 hips underwent femoral impaction grafting in 207 patients. No deaths were attributable to the revision surgery. 33 patients with 35 functioning hips died with less than 5 years follow up. Only one patient was lost to follow-up. There were two (1%) acute infections. Twelve stems underwent a further surgical procedure for aseptic failure – 10 for treatment of femoral fracture and 2 for mechanical loosening in the absence of fracture. Results: Survivorship with any femoral re-operation for any cause as the end point is 90.5% (Confidence Interval 82–98%) at 10–11 years. Using femoral re-operation for symptomatic aseptic mechanical loosening as the endpoint the survivorship was 99.1% (Confidence Interval 96–100%) at the same follow-up. Conclusions: As a consequence of our experience in this series our technique has been modified with an increased use of longer stems with impacted allograft. Long stems are indicated when the host bone around a short stem is significantly compromised, in cases of severe bone stock loss, or when a fracture occurs.
