ABSTRACT

Objective To explore the clinical effect of combination of vascularized fibular head epiphysis and peroneal neurovascular reverse flap repair defects of bone and skin in lateral malleolus in children.Methods Eight children with defects of bone and skin in lateral malleolus were recruited from May,2009 to September,2014.The age of children was ranging from 4 to 12 years old.Four children were injured by wheel twist,2 children were injured by traffic accident,1 was injured by machinery,and 1 was crashed with heavy object.The size of soft-tissue defect was ranging from 3 cm × 5 cm to 7 cm × 9 cm.The flap and bone healing along with ankle joint function scoring were evaluated.Patients were reviewed every 4 to 6 weeks during one year after their surgery,and they were reviewed every 6 months one year later.Results Secondary repair were conducted in all children.The curative effect got well after follow up for 6 months to 2 years(mean,12 months).The flap and fibular head epiphysis were well developed.The ossification of fibular head epiphysis did not found.According to American Orthopaedic Foot and Ankle Society (AOFAS) ankle function evaluation criteria,the results were excellent in 5 cases,good in 2 cases and poor in 1 at 10 months after operation.The shape and function of ankle joint were good,with one exception.The average motion degree of ankle joint was (68±5.12)°.Conclusion Combination of vascularized fibular head epiphysis and peroneal neurovascular reverse flap repair defects of bone and skin in lateral malleolus in children is effective.
