Recent advances in ultrasound technology now permit direct access to f
oetal structures with visualisation of foetal hip development. Since e
arly diagnosis and treatment of congenital hip dislocation significant

nfants 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 f
oetal hip ultrasound is presented. Diagnosis should include qualitativ
e and quantitative descriptions of foetal hip structures. Alpha and Be
ta angles according to Graf's classification are frequently measurable
from the 2 1 st week of gestation, but tend to be more reliable towar
