Abstract

Radiographic changes in the femoral metaphysis in Legg-Calve-Perthes' (LCP) remain poorly understood. Our hypothesis was that these ''cysts'' are not truly metaphyseal but are metaphyseal changes radiographically projected onto the metaphysis. Surface epiphyseal changes were made on a normal hip and a hip with LCP. These ''lesions'' appeared metaphyseal on radiograph, and in the specimen with LCP, projected deep within the metaphysis due to flattening and three-dimensional distortion. ''Metaphyseal'' cysts in LCP may be epiphyseal changes superimposed on the metaphysis. This would explain the correlation between the presence of a ''metaphyseal'' lucency and final result, since it is simply another indicator of the extent of epiphyseal involvement.
