Treatment of nonunion after Pilon fracture with fibula approach fixation of tibia and ankle joint fixation / 中国矫形外科杂志

ABSTRACT

[Objective]To investigate the treatment of nonunion after Pilon fracture with fibula approach fixation of tibia and ankle joint fixation and its clinical efficacy.[Method]Six cases of nonunion after Pilon fracture were collected from 1999 to 2004,which included 4 males and 2 females,with the average age of 34.7 years(21~53 years).All fractures were found invasion to the tibia-fibula joint and ankle malformation.Fibula and tibia were opened from posterolateral approach and reconstruction plate was placed laterally on the fibula,with screws crossing the fibula into the tibia directly.Autogenous bone graft was used in fracture position and area between tibia and fibula to gain tibia-fibula fusion.[Result]All cases were followed up from 8 months to 4 years with the average of 22 months.Bone fusion were gained in 5 cases with the average time of 3.5 months.Plate broken was found in 1 case for too early weight bearing.[Conclusion]Fibula approach fixation of tibia and ankle joint fixation has advantages of promoting fracture healing,preventing complications,and correction joint malformation.It is a convenient and reliable method for clinical surgeons.
