Sonography of baby hips for the diagnosis of DDH and dysplasia has grown steadily in importance in recent years. A strict standardized technique for investigation of the baby and interpretation of the sonograms has made hip ultrasound reproducible, reliable and independent of examiner skill and experience. Graf’s technique is now used worldwide, and selective or even general screening programmes for all babies are established in many European countries today. The first part of this book includes the fundamentals of hip sonography, static as well as dynamic techniques, anatomical identification of the echograms, typing, a measurement technique and usability check. The second part is an atlas including a summary of the essential data and demonstrating correct and incorrect sonograms in different variations. The book is indispensable for everyone dealing with DDH problems in diagnosis and therapy.
