Infantile coxa vara.
Infantile coxa vara is an unusual localized dysplasia, not evident at birth, which is first noticed when the child begins walking. Twelve cases are presented with emphasis on the characteristic roentgen findings which include abnormal ossification of the femoral neck, a vertical physis, a characteristic triangular osseous fragment at the medial inferior corner of the metaphysis, and a straight femoral shaft. Prompt diagnosis and early management can reduce severe deformity and degenerative changes of the hip. For this reason, infantile coxa vara must be differentiated from other generalized and localized causes of coxa vara, including congenital dysplasias and acquired abnormalities.
