Use of the Ilizarov technique to improve limb function following hemipelvectomy

Aims: Limb salvage surgery combined with tumour resection has become established in the management of pelvic tumours. However, subsequent reconstructive options for maintaineance of quality of life lead to varied outcomes. We present a hitherto undescribed use of the Ilizarov technique as a second stage adjunct, for the optimisation of function, after first stage tumour resection and arthrodesis. Methods: We describe the surgical technique used to address leg length discrepancy and abductor dysfunction following internal hemipelvectomy with ischifemoral arthrodesis. Distal femoral and distal tibial lengthening using circular frames, with a valgus subtrochanteric femoral osteotomy, enabled a rapid correction of both anomalies. Controlled varus correction at the distal femoral osteotomy site was performed to obtain a horizontal joint line at the knee. Conclusion: The Ilizarov technique is suitable for selected patients with tumour free survival following the initial resection. Our experience indicates that it is a good alternative to a mammoth one stage internal hemipelvectomy with reconstruction. The latter is often attempted even though there is a high risk of local recurrence and distant metastasis. (C) 2002 Elsevier Science Ltd. All rights reserved.
