• The image is showing anterolateral bowing of tibia, which is commonly seen in congenital pseudoarthrosis of tibia.

Congenital Pseudarthrosis of Tibia:

• The child may be born with a fractured tibia, or the bone may be attenuated and then fracture some months later.
• Fracture fails to unite or heals very poorly only to fracture again shortly afterward.
• By the age of two years, the leg is noticeably short and bowed anterolaterally.
• It becomes an intractable condition that will not yield ordinary forms of fracture treatment.
