Congenital Pseudarthrosis of the Fibula

Isolated congenital pseudarthrosis of the fibula (CPF) may be associated with progressive ankle valgusAnkle valgus and rarely progresses to tibial insufficiency fractureTibial insufficiency fracture and potential pseudarthrosis. An isolated CPF with ankle valgus is therefore indicated for treatment to correct ankle alignment and avoid late development of tibial pseudarthrosis. Growth modulation Growth modulation(hemi-epiphyseodesis of the medial distal tibia) is preferred if feasible (immature patient), or supramalleolar osteotomy (acute or gradual), if mature, may be employed. Stabilization of the fibula defect should be accomplished by either direct repair Direct repairor distal tibiofibular synostosisDistal tibia-fibula synostosis.
