[Reconstruction of the long bones of the legs in children via free vascularized transplant of the fibula after resection for sarcoma].
Nineteen children were operated on between 1985 and 1994. All the patients presented a sarcoma of long bones: osteosarcoma: 12 and Ewing's sarcoma: 7. They were operated on: resection and reconstruction of the long bones with a free vascularised fibula. Pre and post-operative chemotherapy was used. The average follow-up was 3 years (between 10 years and 1 year). The mean bone defect was 20 cm (between 32 and 11 cm). Boys were more frequently encountered [12]. Average age was 9.5 years. The pathological bone was: femur: 14, tibia: 4, humerus 1. The approach needs usually two incisions for femoral bone: the internal incision allows us to prepare the recipient vessels: deep femoral vessels in 11 cases. In 18 cases, union occurred in less than 14 months. One case of pseudarthrosis occurred. Immediate follow-up was simple in 17 cases. Infection was observed in 2 cases. Secondly, the most frequent complications were: fracture of the fibula: 6 cases, vicious cal: 2 cases; delayed union: 6 cases; stiffness: 2 cases. One patient died later from pulmonary metastasis. Solid osteosynthesis of the member and of the free vascularised fibula permit to shorten these delays. Success depends on two criteria: the graft thickening of the fibula and union of the fibula at both ends. The micro vascular anastomoses must be excellent. Twelve children had bone union with only one operation. In the 6 cases of delayed union, secondary bone grafts give consolidation. The comparison of this technique with standard treatment showed an evident superiority of the free vascularised fibula transplant in extensive defects of bone. The fibula is a life bone which permits rapid union with a short hospitalization, a quick recovery and an early return to school. Free vascularised fibula permit to ameliorate the quality of survival.
