What are the distinguishing features of the epiphyseal dysplasias?
Epiphyseal dysplasia is characterized by abnormal ossification of the developing epiphysis. The resulting morphologic abnormalities of the ossification centers are used to differentiate the various subtypes within this category. The most important epiphyseal dysplasias from a rheumatologic standpoint are multiple epiphyseal dysplasia (MED) and SED.
