Refracture, a Potential Complication of the Periosteal Flap Technique Without Bone Graft for Isolated Congenital Pseudarthrosis of the Fibula: A Report of Two Cases and Literature Review.

Background: It is a rare condition defined by congenital pseudarthrosis of the fibula (CPF), which may be associated with neurofibromatosis (NF) and congenital pseudarthrosis of the tibia. A condition such as this may be symptomatic or asymptomatic, but it requires treatment because of the progression of signs such as ankle valgus and pseudarthrosis of the tibia. There are a number of surgical techniques that can be used to treat this condition, such as tibiofibular fusion, internal fixation, the Ilizarov method, and periosteal flap.
