Abstract
This article simplifies the radiologic diagnosis of skeletal dysplasia by first presenting an ordered approach for analysis of standard radiographs done for skeletal dysplasias. With that foundation, a more detailed discussion of three separate families of skeletal disorders follows. Similarities among dysplasia group members are discussed to provide a certain connectedness among dysplasias. The paper also elucidates the scientific basis behind the radiographic findings so that previously purely descriptive terms have the weight of understanding behind them.
