title: [Post-traumatic cortical defect: presentation of a case].
abstract: Post-traumatic cortical defect appears 3 months after greenstick or torus fractures in children. This entity is asymptomatic and usually located just proximal to the fracture site. The most frequently affected bone is the distal radius. The pathogenesis of this lesion remains unclear but it seems to be caused by an intramedullary fat and blood accumulation beneath a intact periostium. Its diagnosis is based on CT and MR images and no treatment is needed, because its resolution is the rule. There are only 25 cases reported in English literature, we present another one after an epiphisiolysis in the distal radius.
