Abstract
Introduction: Osteochondral reconstruction following tumour resections has a high complication rate. We hypothesized that the vascularised fibular graft as a supplement to the allograft reconstruction following tumour resections would provide a biological solution.
Purpose of the study: A prospective study of the results of patients receiving large fragment allografts and vascularised fibular grafts following tumour resections around the hip and the knee.
Patients and methods: 18 patients underwent resection of primary malignant bone tumors followed by reconstruction with large fragment allograft and vascularised fibular graft. 8 patients underwent resection arthrodesis of the hip, six underwent resection arthrodesis of the knee and five underwent intercalary resections around the knee followed by a large fragment allograft and vascularised fibular graft reconstruction to span the gap left by resection. The patients were assessed clinically (MSTS scoring system) and radiologically at regular intervals.
Results: There were 14 males and 4 females, with a mean age of 26 years (12–70). Mean follow-up was 65 months (8–144). Five patients died of metastatic disease but without local recurrence. In six of the patients with resection arthrodesis of the hip, there was evidence of fracture of the allograft but without the failure of the construct. One fibula fractured but eventually healed uneventfully. There were no cases of non-union in cases of intercalary resections. All the patients scored good or excellent in the MSTS scoring system.
Discussion: Our experience clearly indicates that tumour resection followed by reconstruction with large fragment allograft and vascularised fibular graft is a useful limb salvage procedure providing a biological long-term solution with superior results when compared to prosthetic reconstruction.
