Abstract
Pasteurized autogenous bone graft combined with a vascularized fibula graft is a good surgical option for the reconstruction of wide bone defects after resection of bone tumors, but their long-term follow-up results are still unclear.
We reviewed the long-term follow-up of pasteurized autogenous bone graft combined with a vascularized fibula graft in 4 patients with leg malignant bone tumors. And we assessed the bone union, late postoperative complications and function.
The mean duration until bone union of the vascularized fibula graft was 10.8 months, those of the pasteurized autogenous bone graft was 15.2 months and those between the vascularized fibula and the pasteurized autogenous bone graft was 13.0 months. Complete bone union was achieved in all patients. Late postoperative complications included one pseudarthrosis between pasteurized autogenous bone graft and preserved greater trochanter bone, and one fracture. We performed an autogenous cancellous bone graft on the patient with pseudarthrosis. Long term follow-up results revealed a good functional result and no bone resorption. All patients can walk without any kind of external support.
Our results showed that pasteurized autogenous bone graft combined with vascularized fibula for reconstruction of wide bone defects after resection of bone tumors, could provide considerably good postoperative function without serious complications in long term follow-up.
