title: [Technical aspects of ultrasonography of the fetal hip joint].
abstract: Recent advances in ultrasound technology now permit direct access to foetal structures with visualisation of foetal hip development. Since early diagnosis and treatment of congenital hip dislocation significantly influence outcome of the disease, ultrasound screening of newborn infants proved to be the most effective method. In our study assessment of the foetal hip has been carried out to provide basic knowledge on foetal hip development from 14.-40. weeks of gestation. Technique of foetal hip ultrasound is presented. Diagnosis should include qualitative and quantitative descriptions of foetal hip structures. Alpha and Beta angles according to Graf's classification are frequently measurable from the 21st week of gestation, but tend to be more reliable towards the end of pregnancy.
