During from 24 Oct. 1971 to 31 Aug. 1976, 3580 newborn babies were examined by orthopedic surgeons using five techniques within a few days after birth.Five techniques are as follows, Ortolani's click sign, Palmèn's test, telescoping test, crepitation and limitation of abduction.Click sign was noted in 91 newborns (2.5%).In the group of click sign negative, crepitation was noted in 167 cases, in which acetabular dysplasia was noted in 29 cases. This high incidence of acetabular dysplasia in the crepitation positive group was the most remarkable finding in these examinations.In order to diagnose the joint laxity, these various technique are considered to be useful.A case was reported, which click sign positive in the newborn, but recieved no treatment was become to difficult case.Other treated cases were all obtained excellent results.In these examination, some dislocation were overlooked, and then we consider that taking roentogenograms and reexamination within three months and six months after birth is valuable.
