Blount disease is a developmental condition characterized by disordered endochondral ossification of the medial part of the proximal tibial physis resulting in multiplanar deformities of the lower limb (review by Sabharwal, 2009).
Blount (1937) described 22 cases of bowlegs in infants, with progressive deformity and radiologic findings of sloping proximal tibial epiphysis and a medial beak of the metaphysis.

Blount (1937) described 22 cases of bowlegs in infants, with progressive deformity and radiologic findings of sloping proximal tibial epiphysis and a medial beak of the metaphysis. Blount (1937) suggested the existence of an infantile type with onset in the first year or two of life and an adolescent type developing just before puberty (see 259200). Bathfield and Beighton (1978) noted a predilection for blacks. Duncan et al. (1983) reviewed the literature emphasizing the higher frequency in blacks than in whites, the higher frequency of the infantile form than the adolescent form, and the higher frequency of bilateral involvement than unilateral involvement.
