Ultrasonography in Developmental Displacement of the Hip: A Critical Analysis of Our Results

In a prospective study to evaluate developmental displacement of the hip, we have used real-time sector scanner ultrasonography. One thousand eight ultrasonographic examinations performed on 444 hips were evaluated. The study was performed by an independent assistant who compared his interpretations to the interpretations of the principal authors. The results show that real-time sector scanning has not been proven to be an absolute imaging method. We believe that these disadvantages might be eliminated by proper use of real-time linear scanners.
