[Acute roentgen diagnosis of battered child syndrome. A strategy].

A strategy is proposed for the dedicated interpretation of possible radiographic plain film signs that are suspicious for indicating child abuse. For each sign, the features "PRO" raise the question of abuse, while radiographic or clinical findings "CON" suggest an alternate explanation. Birth trauma, oesteogenesis imperfecta, rescue trauma, and metastatic neuroblastoma are among the many entities cited. A triad of situations may lead a radiologist to look systematically for changes from abuse; a triad of resolutions may result from the search. Periosteal reactions is the major factor in dating of fractures; physiologic periosteal reaction of infancy and periosteal reaction from previous fracture must be considered when so dating fractures.
