This excerpt was created in the absence of an abstract.

The alignment of the capitellum and the radial head is difficult to ascertain from standard radiography because they do not ossify before the age of 9 months. It may therefore not be possible to distinguish between radiohumeral dislocation and a supracondylar epiphyseal fracture in an infant (Dias et al, 1988). We report a case in which dynamic ultrasonic examination provided good definition of dislocation of the radius.
