Abstract:
Objective To investigate the clinical effect of irradiated-host bone ends' union after transplantation of pedicled vascularized fibular periosteum in the treatment of Children's tibia sarcoma.Methods From June,2016 to December,2016,there were 5 children of tibia sarcoma,which were 2 boys and 3 girls,aged of 9-15 years (mean,12 years).They were treated by the re-transplantation of extracorporal irradiated segmental autograft,and used ipsilateral pedicled vascularized fibular periosteum cover the ends of irradiated-host bone to shorten the bone union time of irradiated tibia autograft and prevent nonunion.Patients were 3 cases of osteosarcoma,1 of Ewing's sarcoma,and 1 of relapse of Langerhans's cell histocytosis in tibia.The length of resect bone was 14.0-20.0 cm (mean,17.2cm),constitute of 2 osteoarticular resections and 3 intercalary resections.The method of inactivation of bone segment was intraoperative extracorporal irradiation.Regular followed-up were done postoperative.The X-ray and CT were applied to observe the function of affect limb.The bone union time and complication were record.Results All patients were followed-up of 12-18 months (mean,14.2 months).Eight ends of irradiated-host bone in 5 patients healed completely in 7.8 (6-10) months postoperative.The region of ends were covered by periosteum and showed excellent osteogenic power.There was no leg length discrepancy occurred in patients who received intercalary inactivation because of the preservation of growth plate.But the other 2 osteoarticular inactivated patients suffered leg length discrepancy of 1.0 cm and 1.5 cm respectively because of the inactivation of growth plate.At the follow-up of 12 months post-operation,the mean MTSS of affect limb was 25.8(22-28),and the mean of MTSS％ was 86％(73％-93％).Conclusion Transplantation of pedicled vascularized fibular periosteum can promote effectively healing of irradiated tibia bone after replantation in Children,with simple operation and less complications.
