• BACKGROUND
    • The Wagner SL uncemented revision stem has been utilised successfully for revision hip surgery where marked loss of proximal bone stock co-exists or where there is a periprosthetic fracture. Implanted via the transfemoral approach, one significant difficulty appears to be a tendency for implant subsidence, which in some cases has been troublesome enough to necessitate early revision (usually to a larger prosthesis).
  • METHODS
    • A change in our operative practice allowed us to review the effects of using either wire cerclages or 2.0 mm Dall-Miles cables for prophylactic wiring of the distal femur. Seventeen Wagner SL stems, inserted via the transfemoral approach, were studied in 16 patients.
  • RESULTS
    • We found those patients prophylactically wired with Dall-Miles cables demonstrated no subsidence in comparison with those in whom heavy wire cerclage had been utilised (mean subsidence 6 mm; p=0.001). In addition, we found that closure of the proximal osteotomy with wires conferred a more reliable rate of union in comparison with those closed with heavy sutures.
  • CONCLUSION
    • We recommend the use of Dall-Miles cables for distal cerclage and osteotomy closure for the Wagner prosthesis.
