[Sonography of the hip joint in skeletal dysplasias and chromosome disorders].

The preliminary results of ultrasound of the hip in patients with skeletal dysplasias and chromosomal aberrations are described. Pathology of the hip joint can be demonstrated by ultrasound; especially the entities with abundant cartilage can be visualized by sonography. Ultrasound of the hip is a valuable method in the diagnosis of skeletal dysplasias complementary to plain x-ray surveys.
