Abstract

Subperiosteal Cortical Defect is a symptomless rarefaction of cortical bone which begins most often on the external surface of the medial and posterior cortical walls of the lower end of the femur in children between the ages of 3 and 6 years. The name of Subperiosteal Cortical Defect was first used by Aegerter who differentiated it from non-osteogenic fibroma. The authors found out 5 positive cases of incidental findings among 62 cases of both knee joint X-ray of which 3 was male and 2 was female. Also we experienced 3 cases which necessiat d a correct diagnosis and differential diagnosis. Because this is a common lesion, it frequently accompanies more serious bone conditions, and because this is self-limited disease, treatment is not necessary. It was emphasized that its nature should be understood by all those dealing with bone disease lest it be overdiagnosed and overtreated.
