Denouement and Discussion
Congenital Kyphoscoliotic Tibia
This patient presented an example of congenital kyphoscoliosis of the tibia.Congenital kyphoscoliotic tibia or congenital pseudoarthrosis of the tibia is a rare disease characterized by congenital bowing of the shaft of one or both tibiae at the junction of the middle and lower thirds.
