What condition is characterized by a growth disturbance on the medial proximal aspect of the tibia?

Blount's disease is characterized by a growth disturbance on the medial proximal aspect of the tibia, leading to a bow-legged deformity. This condition is primarily associated with the tibial growth plate and results in abnormal development of the bone, specifically causing a varus alignment at the knee. This disturbance occurs due to excessive loading or abnormal biomechanics of the knee joint, which can hinder the normal growth and development of the tibia.

Children with Blount's disease may present with a gradual onset of bowing of the legs, particularly noticeable during the early years of walking. Early intervention with bracing or surgical options may be necessary to correct the deformity and encourage proper growth and development.

In contrast, Rickets is related to vitamin D deficiency and results in generalized bone softening and deformities, not specific to the medial proximal tibia. Osteogenesis imperfecta is primarily a genetic bone disorder characterized by brittle bones due to collagen defects, while Legg-Calvé-Perthes disease involves avascular necrosis of the femoral head and does not directly impact the tibia.
