Alternating radiolucent and radiodense metaphyseal lines
Corner fracture of metaphysis
Fracture or fragmentation at the lateral portion of the metaphysis of a long bone. The radiographic appearance is that of a small corner of metaphysis separated from the metaphyseal edge by thin linear radiolucency. This feature can be observed in child abuse but fragmented appearance of the metaphysis or facture-like lesions can also be detected in the setting of certain skeletal dysplasias.
