Which disease involves bowing of the tibia (varus) and is often seen in children with obesity?

Bowing of the tibia, referred to as varus deformity, is notably associated with Blount disease, particularly in children with obesity. Blount disease is a growth disorder that affects the growth plates of the tibia, leading to abnormal bone development and a characteristic bowing of the legs. The increased weight and stress on the knee joint from obesity can exacerbate this condition, making it more pronounced in affected children.

Rickets is related to a vitamin deficiency causing weakened bones but typically presents with more generalized skeletal deformities rather than localized bowing. Scoliosis involves a curvature of the spine, unrelated to bowing of the tibia. Osteogenesis imperfecta leads to brittle bones but does not primarily cause varus deformities in the tibia. Therefore, Blount disease is the most relevant choice regarding the specific presentation of tibial bowing in obese children.
