DEFORMITIES IN DEVELOPMENT
—In an attempt to secure a better classification of chondrodystrophies and osteochondrodystrophies, Hirsch1 quotes the classification suggested by Jaffe. The latter coins a new term, "eccentrochondroplasia," since the epiphysis in this condition develops not from a central nucleus but from multiple eccentric centers of ossification, as shown in roentgenograms. There are three stages in this disease: a latent stage, a florid stage and a stage of healing with its aftermath of deformity. Though the condition is not generally recognized until the child begins to walk, roentgenographic signs become apparent with the onset of ossification of the epiphysial cartilages. The visible signs of this condition are: thoracic kyphosis with prominence of the sternum, forward tipping of the pelvis, genu valgum and flat and everted feet. The roentgenographic signs are chiefly epiphysial changes associated with a malacia which produces a deformity in the size and shape
