Blount's disease, also known as tibia vara, is a condition where the growth plate of the lower leg bone is unable to support the child's body weight, causing the leg to bow outward. Medical professionals sometimes use alternative terms to describe Blount's disease. These synonyms include tibia vara, infantile tibia vara, Schmid tibia vara, proximal tibial varus deformity, and osteochondrosis deformans tibiae. While these terms may vary, they all ultimately refer to the same underlying condition, which requires prompt medical evaluation and treatment to avoid complications and ensure a full recovery.
