Introduction. Blount’s disease is progressive pathologic genu varum centered at the tibia; Best divided into two distinct disease entities. Infantile. Blount disease refers to a local disturbance of growth of the medial aspect of the proximal tibial metaphysis and/or epiphysis that results in tibia vara. Blount disease is a growth disorder of the shin bone (tibia) characterized by inward turning of the lower leg (bowing) that slowly worsens over time. While it is not.

The condition is commonly bilateral. Clinically, the child often presents with leg bowing tibia vara with little or no associated pain.
A relative lack of growth of the medial proximal tibial physis occurs, likely secondary to an increase in compressive forces on the proximal tibial physis.
There are infantile, enfermesad and adolescent forms. The infantile type is 5x more frequent than the others and is seen particularly in early walkers. It appears to be the result of abnormal compressive forces inhibiting growth at the medial growth plate and not from avascular necrosis.
The tibial shaft is in the varus position, and the epiphysis is wedge-shaped, fragmented or can appear absent.
The adjacent metaphysis is also depressed and has a beak-like protuberance of rarified bone oriented medially. The lateral cortical wall of the upper tibial metaphysis remains notably straight.
