[Injuries of the elbow and forearm in children]

The article reviews aids in radiological diagnosis of elbow lesions in children. It is most essential to know the anatomical conditions, the development of the ossification centres, of the statisticsl frequency of the individual types of lesions, and of the numerous combined sequels to traumas. The valuable aid given by th roentenological visualisation of the extracapsular fat (anterior and posterior), especially in undefined lesions, is discussed, as well as the importance of other fat pad signs which are helpful in identifying anatomic conditions. Most of the wrong diagnoses can be avoided if a few fundamental points are observed, such as identification of the epicondylus medialis according to age, positive or negative visualisation of extracapsular fat, and visualisation of both adjoining joints in lower arm fractures claimed to be of an isolated nature.
