Abstract;We performed ultrasonographic screening tests for developmental dysplasia of hips (DDH) using the Graf's method on 1,564 infants (3,128 hips) at one month of age and found that 520 hips of 397 infants were sonographically abnormal. Then, we divided these 397 cases in two sobgroups according to Graf's classification, which consisted of 365 infants with type II a physiologically immature hips and 32 with type II c or worse pathologic hips. For the infants with immature hips, we instructed the parents not to restrict hip motion by diapers nad their holding of the infant. The later sonographic examinations perfpormed at three to seven months of age revealed these infants to be normal. In the cases of 32 infants with abnormal hips, 20 were found to be sonographically normal seven months later without orthopedic treatments and 12 were normalized with Riemenbugel attachment therapy for 42-105 days (mean 78 days). None of these required surgical treatment. We recommend an early sonographic screening test of DDH to achieve early diagnosis and early treatment and to avoid delayed detection which will possibly necessitate surgical treatment. (author abst.)
