Sažetak
Developmental hip dysplasia (DDH) is a deformation of the locomotor system that
can occur on previously normal bone structures in late fetal development. The study was
undertaken to determine the value of continuous ultrasound screening in early diagnosis
of DDH. In the area covered by the Labin Primary Health Center, clinical and ultrasound
examination of the hips was performed in all children during the fourth month of
life from 1989 to 2001. The incidence of DDH was 3.3%. The authors compared the obtained
results with results of clinically examined hips in the period from 1968 to 1988
(incidence 1.7%), before the ultrasound diagnostics was introduced. The hip radiograms
were performed only in children with clinically positive signs of higher degree of DHD.
The ultrasound examination was performed with Hitachi EUB 410 real time linear transducer
with a 5 MHz probe. The examiners used methods and criteria suggested by Graf.
The most useful feature of the ultrasound method is that it allows the visualization of
cartilaginous femoral head and its relationship to the acetabulum in infants. The method
is non-invasive, repeatable, without risk of ionizing radiation or need for the contrast
material administration. The results of the study revealed an important increase
of DHD incidence after the introduction of ultrasound examination. US is highly sensitive
in hip imaging and reveals the existence of a number of dislocated and subluxated
hips that otherwise would be missed. The anomaly was discovered in the early period of
life, which is very important for appropriate therapeutic effects.
