A. Tegnander et al., INCIDENCE OF LATE-DIAGNOSED HIP-DYSPLASIA AFTER DIFFERENT SCREENING METHODS IN NEWBORNS, Journal of pediatric orthopedics. Part B, 3(1), 1994, pp. 86-88
We compared the effectiveness of different approaches to hip screening
in newborns. Three groups were studied: children born in our hospital
from 1980 through 1985 who were clinically examined by pediatricians
(group A), children born in 1986 and 1987 who were examined by ultraso
und (US) in addition to clinical examination (group B), and children b
orn in three district hospitals where neonatal clinical screening had
not been performed by pediatricians (group C). There were significant
differences between the three groups in the incidence of late-diagnose
d hip dysplasia (HD): 2.6 in 1,000, 0.7 in 1,000, and 5.3 in 1,000, re
spectively. We conclude that US screening of hips in newborns was more
effective than clinical screening alone and that clinical screening b
y pediatricians was superior to screening by doctors with less experie
nce in examining children. US appears to have the potential to eradica
te late-diagnosed dislocations, but milder degrees of HD still occur.
With regard to the US method, measurement of femoral head coverage app
ears to be more adequate than subjective evaluation only.
