Congenital Tibia Pseudarthrosis - Pseudarthrose.

Management of congenital pseudarthrosis of the tibia (CPT) is most challenging. Almost half of the cases are associated with neurofibromatosis type 1. The problems include a recalcitrant pseudarthrosis of the tibia, deformity, limb length discrepancy, concomitant affected fibula in many cases, ankle valgus, and a notorious tendency for refracture after having healed. These problems are due to.Congenital pseudarthrosis of the tibia (CPT) describes a spectrum ranging from anterolateral bowing of the tibia to frank pseudarthrosis and disappearance of bone. It is strongly associated with neurofibromatosis type 1. While many classification systems exist, the most important criterion is the status of the tibia (fractured versus intact). CPT management is typically surgical, with bracing.Pseudarthrosis Tibia. Between 40% and 80% are associated with neurofibromatosis. Incidence. Estimated to be 1 per 190,000 live births. Aetiology. Exact cellular mechanism is not known and despite a definite clinical relationship with neurofibromatosis, a cellular cause and effect has not been proven.


Congenital pseudarthrosis of the tibia is characterized by anterolateral deformity of the tibia and shortening of the limb. Its etiology remains unclear. Although several classification systems have been proposed, none provides specific guidelines for management. Treatment remains challenging. The goal is to obtain and maintain union while minimizing deformity. The basic biologic.What is Congenital Pseudarthrosis of the Tibia (CPT)? Congenital pseudarthrosis of the tibia is a shin bone fracture in children that has not healed. It normally presents before a child turns two years old. Typically, the child gets a shin bone fracture that either happens spontaneously, or results from when the child experiences a minor trauma, and the fracture will not heal. It is a rare.
