Free Vascularized Fibular Graft for Congenital Pseudarthrosis Tibia: A Case Series

Abstract

Introduction: Congenital pseudarthrosis tibia (CPT) probably one of the most difficult to treat among all diseases in the children. There are several surgical approaches that have been used to treat CPT including on-lay graft, double on-lay grafts, pedicle grafts, osteotomy, bypass graft and intramedullary rods. Prognosis of CPT has changed considerably with the use of Free Vascularized Fibular Graft (FVFG). Despite these advances, several operations are often necessary to obtain union of CPT and the risk of amputation is never entirely eliminated Case presentation: We presented 2 case with CPT. The first case is a 4 year old girl with CPT-Associated Neurofibromatosis, patient was brought to orthopedic polyclinic complaining bend on her right leg since she was born, the parent also complained her child has abnormality when walking since she was 14 months old. The second case is a 3 year old girl with CPT complaining bend on her right leg, abnormalities and pain when walking since she was aged 1 years 11 months. We performed free vascularized fibular graft for both of the patient. Result: The results in our cases showed bone union in 14 weeks, 16 weeks and 18 weeks respectively. The optimal of technique options should be adapted to the type of pseudarthrosis and especially to the extent of the bone defects. good results can be found with intramedullary nailing with a bone graft or the Ilizarov technique Conclusion: The optimal of technique options should be adapted to the type of pseudarthrosis and especially to the extent of the bone defects Keywords: Congenital pseudarthrosis tibia, Free vascularized fibular graft, case series.
