title: [The sonographic evaluation of hip dysplasia using convexity diagnosis].
abstract: The authors report on a method of diagnosing up dysplasia by means of echography. For technical reasons only changes in the bony and cartilaginous acetabular convexity can be used to diagnose hip dysplasia. Four basic types of changes are distinguished to which certain angles can be allocated for the purpose of assessment. In addition to this assessment of the shape of the convexity the assessment of the structure of the cartilaginous and bony convexity in the echogram is especially important. The method enables hips to be classified and their development to be followed closely from birth with no radiation exposure; it thus represents an important extension of our diagnostic facilities.
